SpellBook Finance

by Spellbook Finance

Overview

SpellBook Finance helps Magic: The Gathering sellers research exact printings and market prices, inspect sealed-product value and buylist spreads, manage workspace inventory, and preview or run guarded listing workflows for eBay, ManaPool, and TCGplayer.

Tools

spellbook_agent_gap_report

ChatGPT
After finishing the task, ask the person whether they consent to send one bounded capability-gap report to SpellBook. Call this tool only after an explicit yes for this report and set consentToShare to true. Use it when a needed field was null, you guessed a number because no tool supplied it, you wished a tool existed, or you abandoned a path. It returns no task data and fixes nothing. Generate a fresh ULID submissionId and reuse the exact request for retries within 24 hours. Field paths must be real SpellBook response paths. There is no free-text field: never describe the card, price, customer, or conversation.

spellbook_agent_pricing_protection

ChatGPT
Read a workspace's saved-rule pricing authority before an eBay reprice. Returns current and accepted eBay rules, mode, source-change acceptance requirement, unresolved submission evidence, missingFields and limitations. Settling means earlier admitted marketplace writes may still finish. Only the owner can accept rules through the web app.

spellbook_box_ev_rankings

ChatGPT
Read sealed-product EV rankings with each box's modeled total EV, evRatio, pack standard deviation (packSD), N0 and breakEvenPct, defaulting to the highest evRatio first. Call it for "how many packs until opening is likely profitable" (N0), "how swingy is this box" (packSD, and swinginess, which is packSD divided by packEV) and "what share of packs beat the pack price" (breakEvenPct). N0 is the number of packs at which a normal approximation, treating packs as independent and identical, gives about a 97.7% modeled probability that summed gross card market value exceeds summed pack cost. It is null when per-pack edge is zero or negative. Pack cost is packPrice, the box market price divided by packsPerBox. Each N0 variant uses its own valuation basis, with its own pack SD and edge: n0Full uses full market value (packSD, fullEdge), n0LandAdjusted prices cheap lands at bulk rates (landAdjustedPackSD, landAdjustedEdge), and n0Sellable prices cards below a threshold at bulk buylist rates (sellablePackSD, sellableEdge). All values are gross market value before selling fees, shipping and liquidity. breakEvenPct is the share of simulated single packs worth at least packPrice. It is not the probability of profit after N packs. Rows also carry exact product IDs, market prices, the acquirableFloorUsd and evRatioBasis behind the stored EV ratios when present, market-basis ratios, market-price spreads, shipping-aware ratios, per-pack metrics and row timestamps. evRatio is totalEV divided by max(marketPrice, the cheapest captured TCG listing price plus shipping) on rows with a known basis; evRatioMarketBasis preserves the market-price comparison. spreadUsd is totalEV minus marketPrice, so it is a separate comparison. typicalEV is the box EV with every card under typicalEvCutoffPerPack (a pull probability of 0.001 per pack) left out, and typicalEvExcludedCount is how many cards that dropped; typicalEV is null when the model cannot compute it, with typicalEvReason saying why. Sort by n0Full, n0LandAdjusted or n0Sellable to order boxes by packs needed. Call spellbook_sealed_product_offers with a row's boxId for store offers on that product. This is modeled research evidence for a caller's decision, not a purchase instruction.

spellbook_buy_outcome_report

ChatGPT
Score every closed buy decision in one workspace against its immutable prediction and a fixed equal-weight printing basket. Includes unscored and abandoned counts, missing baseline evidence and small-sample limits. Uses submitted receipts; does not verify merchant orders or money.

spellbook_buy_targets

ChatGPT
Return a bounded source-order page of materialized TCGplayer-to-Card-Kingdom rows with an opaque nextCursor for complete traversal. Rows include printing identity, observed acquisition and cash quote prices, listed shipping, seller/quantity evidence, exit.quantityBuying (the copies Card Kingdom buys at the quoted price), maxCopies (the smaller of listed stock and exit.quantityBuying), the Card Kingdom condition ladder (NM/EX/VG/G payouts, modeled from the NM quote), timestamps, printingMismatches and missingFields. Call this first when a person says "I have $X to risk", "find me opportunities", "good opportunities", "single cards", "high risk singles", "start with arbitrage" or "what should I buy". Never request more copies of a row than maxCopies. Before handing a person a buy list, record each chosen row as a consideration with spellbook_customer_evidence_record, because spellbook_buy_outcome_report scores only recorded considerations. No profit, ranking, selection, reserves or cost defaults. Exact listing links and fee amounts are null when unavailable. Customer agent supplies all policy and executes purchases.

spellbook_card_buylist

ChatGPT
Read dealer buy offers for ONE exact card product, preserving each offer's game, finish, subtype, language, condition, source product, source timestamp, cash and credit fields, quantity and missingFields. Use the catalog product id from spellbook_printings_search. Pokemon offers are English NM/New CoolStuffInc observations when present; no offer or missing field proves a dealer has no stock. This read returns facts and does not choose a vendor or sell cards.

spellbook_card_buylist_history

ChatGPT
Read the stored daily dealer buylist price series for ONE exact printing: one point per day with the Card Kingdom and Cardhoarder buylist price when SpellBook stored one, oldest day first, plus earliestDay, the first day SpellBook holds any stored row for that printing. Use the printing id from spellbook_printings_search. Call spellbook_card_buylist for current offers from every dealer SpellBook reads. This read returns facts; it does not choose a vendor, judge a price or sell cards.

spellbook_card_prices

ChatGPT
Read every price source SpellBook Finance holds for ONE printing, one row per source, each with its own label, price and timestamp. Sources can include TCGplayer Market, TCGplayer Low, Card Kingdom retail and buylist, CoolStuff, an eBay 90-day sold median, Cardmarket, ManaPool and CardTrader. Pokemon TCGplayer finish subtypes stay in separate rows. cardId is the exact printing id returned by spellbook_printings_search: a UUID for Magic, or a catalog product id for Riftbound or Pokemon. Rows come back in source order with their own timestamps; nothing is averaged, ranked, or chosen for you, and no listing link is returned.

spellbook_channel_lane_set

ChatGPT
Set one workspace's lane mode for one channel-lane marketplace, the switch that decides whether SpellBook reads the marketplace or changes listings there. This changes public marketplace behavior for the workspace, only the workspace owner may call it, and the agent sets a mode only after the seller chose one. It returns the same lane state as spellbook_marketplace_onboarding. The modes: off: the lane is disabled and SpellBook neither reads nor changes the marketplace. observe: SpellBook reads the marketplace and records whether it matches SpellBook's desired state, and never changes a listing there. push: SpellBook creates, updates, and removes listings on the marketplace to match its desired state.

spellbook_channel_pricing_profile_set

ChatGPT
Pin one of the workspace's saved pricing profiles to one marketplace channel, or clear the pin with a null profileId. It is the same choice as the channel defaults card on the SpellBook pricing settings page. Read spellbook_channel_pricing_profiles first, and pin only a profile the seller named. Returns the full channel pricing read after the write, plus the channel's previous pin, so the change can be reverted by setting the previous value back. It changes which profile prices future automatic listings and reprices; it edits no profile and publishes nothing.

spellbook_channel_pricing_profiles

ChatGPT
Read which saved pricing profile each marketplace channel prices from in one workspace. Automatic eBay listing and repricing price every card from the eBay channel's profile, so read this before a seller turns on automatic eBay listing. Returns the workspace's saved profiles by name with the active one marked, and for each channel the pinned profile, the profile automation actually prices from, and which SpellBook jobs read that pin. It reports the setting and recommends no profile.

spellbook_collection_buying_get

ChatGPT
Read the current snapshot or one immutable revision of a collection deal owned by the selected workspace. The response includes the selected revision's command and receiptId so submitted terms and corrections can be audited. Read the collection-buying skill before interpreting lifecycle state.

spellbook_collection_buying_list

ChatGPT
List a bounded page of collection deals in the selected seller workspace. Follow nextCursor to enumerate the full set, then read a deal for its latest or historical revision and source command.

spellbook_collection_buying_record

ChatGPT
Record one seller-agreed collection deal or a later receipt, count correction, evaluation, seller response, reported payment/refund, return/title disposition, dispute, closure, or evidence-backed reopening. Read spellbook_skill(name: collection-buying) first. A submission is an immutable, owner-scoped receipt; retry its exact submissionId and payload after an uncertain result. It records evidence only: it does not contact a seller, send money, verify a reported payment, transfer title, receive inventory, or publish cards.

spellbook_credit_conversion_candidates

ChatGPT
Read CK credit-funded sealed acquisition candidates ranked by opening EV. Cash/credit opening multiples do NOT rank intact sealed resale cash profit. Credit is restricted purchasing power.

spellbook_credit_resale_assessment

ChatGPT
Assess up to ten exact sealed product lines as a CK-credit-funded intact resale scenario. Supply starting credit and explicit cost assumptions; omit unknown costs. EV judgment is permitted. Returns labeled cash estimates, credit allocation, capacity and missing evidence. Research only, no purchase.

spellbook_customer_evidence_get

ChatGPT
Read one private immutable evidence receipt from the selected workspace. Returned observations and source fields remain submitted evidence.

spellbook_customer_evidence_list

ChatGPT
List a bounded page of private evidence receipts from the selected workspace, optionally filtered by receipt kind, parent, or item ID.

spellbook_customer_evidence_record

ChatGPT
Append one immutable consideration, realized outcome, or work observation to the selected workspace. A receipt proves storage only. It does not verify source providers, inspected card truth, profit, or completed work.

spellbook_deck_contents

ChatGPT
Read one authenticated customer's exact owned and draft card contents for a deck. The response preserves game identity, entry ids, matched catalog identity, quantities, membership recovery count and Pokemon readiness checks. It reports facts only and does not edit a deck or infer missing cards.

spellbook_deck_import_limitless

ChatGPT
Import one player's Pokemon decklist from one fixed Limitless tournament standings record into the seller's workspace. The workspace owner chooses the event, player, format and idempotency key; retries with the same key replay the first result or report an in-progress import. The tool does not accept URLs or credentials and returns source identity, matched and unmatched counts, and the imported deck.

spellbook_ebay_automation_set

ChatGPT
Set one workspace's eBay automation mode, which decides whether SpellBook lists and reprices on eBay by itself, whether that automation lists basic lands, and how many copies one listing may carry. This changes public eBay behavior for the workspace, only the workspace owner may call it, and the agent sets a mode only after the seller chose one. The modes: manual: Nothing lists or reprices on eBay automatically; you publish from the eBay preview when you choose. auto_list: New eligible inventory lists on eBay automatically at your saved eBay pricing strategy's prices, and existing eBay listings are never repriced automatically. full: New inventory lists on eBay automatically, and existing eBay listings reprice from your saved eBay pricing strategy. With variation packages on (the default), new inventory groups into one listing per set with each card as a variation; with them off, each card lists on its own.

spellbook_ebay_combined_shipping_get

ChatGPT
Read the caller's connected eBay combined-shipping profile and promotional shipping rule, including its provider type, amount threshold or maximum order cost, and configuration status. Call spellbook_ebay_combined_shipping_set after reviewing it. eBay checkout may still require multiple items for an amount-threshold offer; use eBay Seller Hub Shipping discounts when a minimum amount must qualify one item.

spellbook_ebay_combined_shipping_set

ChatGPT
Set the caller's connected eBay combined-shipping charge and optional amount-threshold offer or maximum shipping cost per order, then return Account API readback. Read spellbook_ebay_combined_shipping_get first. Configure an amount-only single-item Shipping discount separately in Seller Hub.

spellbook_ebay_connection_status

ChatGPT
Check whether this signed-in customer's eBay seller account is connected to SpellBook Finance. Call this before requesting a connect link and call it again after the seller approves eBay consent. It returns the stored account identity and token state plus current eBay seller-registration and selling-limit facts. If connected is false and account is null, call spellbook_ebay_connect_link. If status is revoked, fetch a fresh connect link.

spellbook_ebay_job_status

ChatGPT
Read one eBay bulk job by the jobId returned from spellbook_ebay_publish or spellbook_ebay_reprice. Both operations queue work, so call this before telling the person a listing was created or its ask changed. State planning, pending, uploading, processing or ingesting means the job is still running: call again after about a minute. State failed carries errorMessage, and each failures row carries a per-card reason: relay that reason to the person. A job with dryRun true is a reprice preview: it changed no eBay price, and totalItems counts the listings a live run would reprice. Returns state, counts, per-card items, failures and missingFields.

spellbook_ebay_order_discount_get

ChatGPT
Read the caller's tracked eBay order-discount promotion, including store or lot scope, quantity threshold, percentage, status and dates. workspaceId is checked for owner access; the promotion belongs to the caller's connected eBay account.

spellbook_ebay_price_limit_enrollment_continue

ChatGPT
Advance one bounded discovery step of an existing eBay enrollment and return its header. Read spellbook_ebay_price_limit_enrollment_get first for the current state version. The server chooses each discovery page; repeat from fresh readback while building, then ask the owner to review in the web app.

spellbook_ebay_price_limit_enrollment_get

ChatGPT
Read one eBay price-limit enrollment's state, coverage counts, fingerprint and original expiry. Call after preparation or continuation. Read stored baselines with spellbook_ebay_price_limit_enrollment_pages; continue building with spellbook_ebay_price_limit_enrollment_continue.

spellbook_ebay_price_limit_enrollment_pages

ChatGPT
Read bounded stored pages of eBay enrollment identities, observed baselines, absolute bounds and exclusions. Call after spellbook_ebay_price_limit_enrollment_get. Follow nextCursor until null to inspect all stored pages; read the header again for overall completion.

spellbook_ebay_price_limit_enrollment_prepare

ChatGPT
Prepare an account-wide enrollment proposal from explicit owner-selected bounds and times. Returns a durable header and coverage counts. Explain the quiet interval prerequisite before calling: controlled price admissions and relevant membership changes can invalidate discovery. Continue with spellbook_ebay_price_limit_enrollment_continue; the owner reviews and activates in the web app.

spellbook_ebay_price_limits_get

ChatGPT
Read active and pending eBay fixed-baseline price limits, enforcement status and missing evidence. Call before preparing a new enrollment with spellbook_ebay_price_limit_enrollment_prepare. Expiry stops new admissions; earlier admitted writes may still finish.

spellbook_ebay_pricing_approval_execute

ChatGPT
Execute the frozen targets of an owner-approved exact eBay pricing batch. First prepare with spellbook_ebay_pricing_approval_prepare and read owner approval with spellbook_ebay_pricing_approval_get. Returns durable execution and per-listing outcome evidence; read the same operation again to inspect progress.

spellbook_ebay_pricing_approval_get

ChatGPT
Read one exact eBay pricing batch's immutable targets, owner approval state and per-listing submission and readback evidence. Call after preparation or execution. Use spellbook_ebay_pricing_approval_execute only after owner approval; keep unknown submissions distinct from observed prices.

spellbook_ebay_pricing_approval_prepare

ChatGPT
Prepare an immutable eBay pricing batch from selected inventory items. Returns exact listing identities, executable USD cents, complete physical membership and approval state. Ask the owner to review the batch in the web app, then call spellbook_ebay_pricing_approval_get before execution.

spellbook_ebay_pricing_restoration_prepare

ChatGPT
Prepare a new exact eBay pricing approval from selected accepted source receipts. Returns eligible listing identities, typed conflicts and missing evidence. First read the source with spellbook_ebay_pricing_approval_get. The owner must choose manual automation and approve the new compensation in the web app; read its approval before spellbook_ebay_pricing_approval_execute.

spellbook_ebay_publish

ChatGPT
Publish owned copies from one workspace as live eBay listings, priced by a stated rule. Pass itemIds to publish one exact card. ALWAYS call it once with dryRun true and show the person the counts and the preflight before calling it again with dryRun false, because a live run creates real listings a real buyer can buy. Pricing anchors on market price, never on what the seller paid: multiplier 0.96 lists at 96% of market, and floorUsd only ever raises a price. A live run returns a queued jobId, or the reason nothing published. A queued job has listed nothing yet, so call spellbook_ebay_job_status with that jobId before telling the person any card is live.

spellbook_ebay_reprice

ChatGPT
Preview or reprice existing live eBay listings in one seller workspace using owner-accepted saved rules or a market multiplier and optional floor. Read spellbook_agent_pricing_protection first. A workspace in saved_rules_only mode requires pricing saved_rules; the server uses its accepted rules. This is a one-run marketplace override: it changes current eBay asks, creates no listing, and saves no pricing profile or durable override. Preview first with the default dryRun true. A preview with itemIds returns its counts at once. Any other preview returns state planning and a jobId, so read its counts with spellbook_ebay_job_status. An explicit dryRun false queues an async reprice job. Read that job with spellbook_ebay_job_status until each affected listing reaches its terminal state.

spellbook_ebay_shipping_mode_get

ChatGPT
Read the shipping-mode preference saved for the caller's connected eBay account and whether a delegated agent last set it. workspaceId proves owner access only; the preference is account-scoped.

spellbook_ebay_shipping_mode_set

ChatGPT
Save the seller-selected shipping mode for the caller's connected eBay account, then return the saved preference. Read spellbook_ebay_shipping_mode_get first; call spellbook_ebay_shipping_policy_set separately to configure charges. This can affect future listing and repricing work across the account's workspaces.

spellbook_ebay_shipping_policy_get

ChatGPT
Read the caller's connected eBay shipping charges and provider readback. workspaceId proves the caller owns a SpellBook workspace; eBay settings remain scoped to that caller's connected eBay account. Read this before changing shipping charges.

spellbook_ebay_shipping_policy_set

ChatGPT
Set a package flat shipping charge and optionally an envelope charge on the caller's connected eBay account, then return provider readback. Read spellbook_ebay_shipping_policy_get first; omitting the envelope amount preserves its current charge. workspaceId is checked for owner access; the connected account belongs to the caller.

spellbook_ebay_unpublish

ChatGPT
End the live eBay listings for up to 25 exact copies, and keep each copy in inventory so it can be published again. Take Item ids from spellbook_inventory_items_query. Show the person which cards will come down and get a yes before calling, because a live listing ends at once. Returns one result per copy: unpublished, kept, no_listing, or failed.

spellbook_entitlements

ChatGPT
Read this authenticated customer's current Investor and Seller access. Flags are not proof of payment or enrollment.

spellbook_free_seller_workspace_claim

ChatGPT
Claim the one permanent free Seller allowance for a workspace the seller explicitly chose. Ask the seller to name the workspace from spellbook_workspaces_list and confirm that choice before this call. Never pick a workspace from list order or an active-workspace default. The signed-in person must own it. Re-read spellbook_workspace_plan_status after this call for the actual allowance and entitlement.

spellbook_guides

ChatGPT
Find a cataloged SpellBook Finance customer-agent guide for seller setup and onboarding, selling, pricing, sealed EV, or choosing a card or sealed-product strategy for a budget and workload. Use it when a customer asks how to make money with Magic, what to do with a bankroll or store credit, whether to open or resell sealed product, or which research route fits their goal. Returns each guide's purpose, supported decision, and URL; read that page for its tool sequence and field meanings. Public search-acquisition articles are excluded. For screening, valuing, or messaging about a Pokémon collection or Marketplace lot, read spellbook_skill with name collection-buying.

spellbook_inventory_bin_ensure

ChatGPT
Record physically confirmed cards into one inventory bin, by stating the DESIRED TOTAL quantity of each exact printing that belongs in that bin. Existing live copies count toward that total, so only a missing difference is created. Calling it twice with the same numbers creates nothing the second time. Use it for the first cards a seller enters by hand, with no CSV and no scanner. Returns the created item ids plus every candidate it refused and why.

spellbook_inventory_holdings

ChatGPT
Read one page of what a seller's own workspace holds, aggregated to one row per printing, finish and condition. Each row carries card name, set code, collector number, variant label, quantity owned, quantity available, the current unit market price and the resolved minimum-sell floor with the tier that produced it. Call this to answer what is in the collection, what it is worth, what is already listed versus still available, and which rows sit near their floor. It reports holdings; it does not rank them, pick what to sell, or state a listing's live marketplace status.

spellbook_inventory_import_csv

ChatGPT
Import a seller's own ManaBox export or TCGplayer inventory export into one workspace, the same import the SpellBook Finance web app runs. The server parses the CSV, resolves each row to an exact printing, preserves mapped location labels or assigns fallback bins, and creates one inventory copy per card. TCGplayer Pokémon and Riftbound rows require the catalog's exact game, provider product identity, finish, condition, and language; incomplete or mismatched rows are skipped with a repair reason and never default to Magic, English, or nonfoil. Sending the identical CSV again returns the first result with duplicate true and creates nothing. Returns the importId, how many copies were written, the bins used, and every row it could not parse or skipped.

spellbook_inventory_incoming

ChatGPT
Read what a workspace has bought or saved that has not arrived yet, one group per marketplace order or precon deck import. Each group carries its acquisitionSource, a readable title, the copy and card counts, the total cost, the date it was recorded and the bins its copies are assigned to. Call this to answer what is still on the way, or to find the acquisitionSource to receive. It reports pending groups; it does not track a package or say when one will arrive.

spellbook_inventory_incoming_receive

ChatGPT
Mark every pending copy in the named orders or precon imports as received, which makes them owned inventory that can be listed and sold. Returns how many copies were received, their total cost and the bins they belong in. Call it when the customer says the package arrived and they counted the cards. Read spellbook_inventory_incoming first to get each acquisitionSource.

spellbook_inventory_items_query

ChatGPT
Read one private page of existing physical Items matching an exact acquisition source, exact bins, or printing, finish and condition groups. Coordinate filters narrow source or group results. Each Item carries scanPlacement, its approximate position in its scanned bin as ordinal of total, or null when it was never scanned there.

spellbook_inventory_location_confirm

ChatGPT
Save up to 25 existing Item bin locations after comparing each expectedBins observation with current state. A fresh Item query is required before and after the save.

spellbook_inventory_precon_import

ChatGPT
Add one or more opened Commander precon decks to inventory as individual cards, the same Add Commander deck flow the SpellBook web app runs. The server reads the cached decklist for that TCGplayer product, creates one inventory copy per card at the exact deck printing, assigns bins, and splits the price paid across the cards. Returns the importId, how many copies were written, and the count placed in each bin.

spellbook_japan_source_scan

ChatGPT
Read the latest bounded Japan sourcing cohort: English Riftbound cards sold in Japan (riftbound-jp), Japanese-language Magic promos (japanese-promos), or exact-language Pokemon cards (pokemon, pokemon-en, pokemon-ja). Returns every tracked target's actual observation time, verified offers, exact reference prices with price kinds, unresolved listing URLs and recorded blockers, source status and freshness policy. publishedAt is snapshot publication time and does not refresh an older target. Sold and unrelated observations are not purchase candidates. Missing costs remain unknown; no buying recommendation or profit is provided.

spellbook_japanese_sourcing

ChatGPT
Read Japanese-market supply offers for the Japanese promo cohort from Mercari, Hareruya and Bigweb, each beside the comparison prices SpellBook holds on TCGplayer, ManaPool and eBay. Every row carries one exact supply offer with its printing identity, the merchant's own condition grade and its normalized equivalent, the native unit price with its currency, quantity, availability, and its own observedAt and staleAfter stamps; then every comparison reference with its kind and typed comparisonBasis, a deterministic selectedReference with the selectionRule that chose it, and a providerStatus row for each comparison source explaining why it is ok, missing, stale, failed or incompatible. grossDifferenceUsd is an asking spread and is null unless printing, language, finish, unit basis and condition equivalence all hold; netDifferenceUsd stays null because this read carries no costs. Rows come back in source order, and nothing is ranked, scored or recommended for you.

spellbook_manapool_automation_set

ChatGPT
Set one workspace's ManaPool automation mode, which decides whether SpellBook creates, updates, delists, and reprices ManaPool listings by itself. This changes public ManaPool behavior for the workspace, only the workspace owner may call it, and the agent sets a mode only after the seller chose one. The modes: manual: SpellBook creates no ManaPool listings and sends no quantity changes or delistings, but it keeps repricing your existing ManaPool listings. assisted: SpellBook plans the ManaPool listing changes it would make but sends none of them and offers no approval step, and it keeps repricing your existing ManaPool listings. automatic: SpellBook creates, updates, and delists ManaPool listings as your inventory changes and reprices existing ones, once the workspace passed a ManaPool test publish and while ManaPool reports the account ready to sell. paused: SpellBook sends nothing to ManaPool: no new listings, no quantity changes, no delistings, and no repricing.

spellbook_manapool_connection_status

ChatGPT
Check whether this signed-in customer's ManaPool seller account is connected to SpellBook Finance. Call this before requesting a setup link and again after the seller finishes the setup form. It returns a masked account identifier and stored connection timestamps. If connected is false, call spellbook_manapool_connect_link.

spellbook_manapool_sync_apply

ChatGPT
Send a previewed batch of changes to ManaPool, creating, repricing and removing real listings. Takes the previewToken from spellbook_manapool_sync_preview, which must still be valid. Applies at most maxActions in one call and returns remainingActionCount with nextActionCursor, so a full book takes several calls. Show the person the preview before the first call, not after.

spellbook_manapool_sync_preview

ChatGPT
Compare one workspace's inventory against what is live on ManaPool, and return the exact changes a sync would make. Every action is listed with its kind: upsert to create or change a listing, delist to remove one, blocked where a cross-channel check refused it. Nothing is sent to ManaPool by this call. Show the person the summary and the counts, then call spellbook_manapool_sync_apply with the previewToken this returns.

spellbook_movers

ChatGPT
Read which card printings changed price the most over one window: daily, weekly, 30d or 90d. Returns gainers and losers with exact game, catalog product, language, finish and marketplace variant when the source provides them, plus current and previous prices, dollar and percent change, a canonical SpellBook Finance cardUrl, and run timestamps. Call this to answer "what is moving this week" instead of guessing, then call spellbook_card_prices for one printing's per-source prices. An unavailable result names why no supported rows can be returned.

spellbook_pokemon_arbitrage_spreads

ChatGPT
Read bounded Pokemon acquisition and exit quote facts for exact product identity, preserving quote basis, currency, observation time, source reference, source URLs, comparisons, missingFields and limitations. This read compares observed sources; it does not rank opportunities, recommend a purchase, or execute a transaction.

spellbook_pokemon_ath

ChatGPT
Read the latest Pokemon all-time-high facts for the retained daily snapshot. Rows preserve exact product identity, language, finish, variant, source date, previous ATH and history coverage. This is a facts-only read; unavailable or partial history stays explicit in availability, missingFields and limitations.

spellbook_pokemon_market_analytics

ChatGPT
Read exact identity scoped Pokemon market facts for ONE catalog product: language, finish, condition, independent retail fair value, observed supply depth, versioned SCORE factors and Limitless demand coverage. The response keeps qualified values null when source count or comparable history is missing, and names missingFields and limitations. It reports facts only; it does not rank cards, recommend an action or infer a missing source.

spellbook_pokemon_metagame_archetype

ChatGPT
Read observed Pokemon archetype and card facts for one format and exact archetype name from recent Limitless tournament decklists. The response preserves source coverage, card prices, truncation, missingFields and limitations. It reports observations and does not recommend a deck or purchase.

spellbook_pokemon_metagame_card

ChatGPT
Read observed Pokemon card demand facts for one exact catalog product, optionally narrowed to one format. The response preserves exact card identity, sample windows, counts, prices, coverage, missingFields and limitations. It reports observations and does not rank or recommend a card.

spellbook_pokemon_metagame_overview

ChatGPT
Read observed Pokemon archetype coverage for one format from recent Limitless tournament decklists. The response preserves archetype facts, sample coverage, truncation, missingFields and limitations. It does not measure the whole player population or predict demand.

spellbook_pokemon_tcg_staged_preview

ChatGPT
Preview the TCGplayer CSV rows for 1 to 25 exact Pokemon physical inventory copies in one workspace. Call this after the seller selects the copies they want to inspect. It returns the existing staged-preview rows and CSV; it queues nothing, publishes nothing, and offers no publish or export follow-up.

spellbook_pricing_amendment_create

ChatGPT
Create one bounded seller pricing amendment from a selector, marketplace scope, absolute multiplier and optional protected band. Returns saved readback. The server retains its adaptive default internally; this tool has no demand behavior input and does not publish or reprice.

spellbook_pricing_amendment_delete

ChatGPT
Delete one saved pricing amendment by exact amendment id and return a deletion readback. This changes saved configuration and does not publish or trigger repricing.

spellbook_pricing_amendment_get

ChatGPT

spellbook_pricing_decision_explain

ChatGPT
Read one seller listing's recorded pricing evidence for one marketplace. Returns the last recorded ask, market anchor, safe price effect, decision timestamps and whether the evidence is observed, recorded, projected or missing. Call this when a seller asks what price was saved or what evidence supports it, then use the seller controls tools when they want to inspect or change a setting. It never claims a remote marketplace ask is current without a remote observation timestamp.

spellbook_pricing_profile_activate

ChatGPT
Activate one seller-selected pricing profile and return its saved readback plus resulting active profile id. The first profile remains inactive until this explicit call. Activation does not publish or trigger repricing.

spellbook_pricing_profile_create

ChatGPT
Create one seller pricing profile from a seller-selected name and explicit baseline multiplier and floor, with optional dollar offset, ordinary channel overrides, or a fixed equal-probability eBay base-price trial. A trial requires an explicit experiment id, positive allocation epoch and two different seller-selected multipliers. Returns saved profile and pin readback. It does not activate, publish or immediately reprice.

spellbook_pricing_profile_get

Each order carries its tray slot and card lines with bin, printing, condition, and state, including blocked reasons and ship-by evidence when available. Use when a seller asks what to pull or pack. Read spellbook_skill for fulfilling-orders before coaching the workflow; follow nextCursor until hasMore is false before summarizing the full returned workset. Use pending lines for the shared bin walk, then verify and pack each order separately.

spellbook_purchase_incoming_record

ChatGPT
Record single cards the customer bought on a marketplace that have not arrived yet, one row per exact printing with the quantity and the price paid per copy. Each copy is written as pending receipt under one order, so it counts as incoming and cannot be listed or sold until it is received. Returns the order's acquisitionSource, the copy count, the total cost and the bins the copies will go into. Use it right after the customer completes a marketplace checkout for singles found through spellbook_buy_targets or spellbook_singles_buylist_spreads. It never buys anything and moves no money. A card already in hand goes through spellbook_inventory_bin_ensure instead. When the package arrives, call spellbook_inventory_incoming_receive with the returned acquisitionSource.

spellbook_return_address

ChatGPT
Read the signed-in seller's saved return address: the name, street line, and city-state-ZIP line SpellBook prints on shipping labels, plus the other settings stored beside it. profile is null when the seller never saved one. Read it before spellbook_return_address_save, so the agent can show the seller what is on file.

spellbook_return_address_save

ChatGPT
Save the return address the seller gave, which SpellBook prints on shipping labels and which store setup counts as returnAddressSaved. It replaces only the name, street, and city-state-ZIP lines and keeps every other saved setting. Only the workspace owner may call it, and only with an address the seller stated. A seller who does not want to share a home address in chat can type it on a SpellBook page, which the limits name, so offer that page before you ask for the address. Call spellbook_store_setup_status afterwards to confirm returnAddressSaved.

spellbook_riftbound_japanese_comparables

ChatGPT
Read physical Japanese-language Riftbound observations, separate from English cards sold in Japan. Returns exact SKU language, finish, condition, price kind, source links, actual price capture timestamps, freshness policy, per-source eligible denominators and nullable acceptance rates. ManaPool is unsupported_game. Distinguishes unavailable, stale, completed eligible zero and accepted evidence. TCG Market is a provider statistic, not a completed sale or guaranteed resale proceeds. asOf is query time. An empty result never implies a market price of zero or proves market-wide coverage.

spellbook_sealed_deal_board

ChatGPT
Read today's Sealed Deal Board rows with their age stamps, so you can answer "what is new since <date>" without diffing the whole board yourself. Each row carries firstSeenAt (the day the board first carried that product), firstSeenBasis, priceBeatenAt with priceBeatenFromUsd (the day its cheapest price fell at least 5% and at least $10 under its own trailing 30-day low), and recencyEventAt, which is the later of the two. Filter and compare these yourself; this returns facts and ranks nothing by recency.

spellbook_sealed_intent_default_set

ChatGPT
Set a workspace rule for future extension-captured sealed purchases. An exact game and productType wins over wildcard rules. Read spellbook_sealed_intent_defaults before and after; existing units keep their current marks.

spellbook_sealed_intent_defaults

ChatGPT
Read a workspace's future sealed-purchase open or hold defaults. Call this before changing how extension-captured products are classified. These rows affect future captures only; spellbook_sealed_portfolio reports marks already on physical units.

spellbook_sealed_listing_pause

ChatGPT
Remove one SpellBook-managed sealed listing from ManaPool or set its TCGplayer quantity to zero through the paired browser. Call spellbook_sealed_listing_preview first and pass its channel and intentRevision unchanged. A product with no saved SpellBook intent cannot be removed by this tool.

spellbook_sealed_listing_preview

ChatGPT
Preview one sealed listing on ManaPool or TCGplayer without publishing. Returns the proposed quantity and ask, any current offer, TCG publisher readback state, stock and intent revisions, and blockers. For TCGplayer, the first call may queue an exact seller-grid SKU read; call again after the paired extension finishes. After submitting, call preview again: publisher.state live confirms an offer, and removed confirms a zero-quantity removal. Pass this preview's channel, ask, and revisions to spellbook_sealed_listing_submit.

spellbook_sealed_listing_submit

ChatGPT
Submit one sealed product listing to ManaPool or TCGplayer at the exact quantity and ask shown by spellbook_sealed_listing_preview. Pass the same channel and product arguments, plus proposed.stockRevision, proposed.askUsd, and intentRevision unchanged. ManaPool submits directly. TCGplayer queues the paired browser writer. A queued TCG write is pending until an exact seller-grid readback confirms it.

spellbook_sealed_portfolio

ChatGPT
Read a seller's sealed boxes, packs and cases, with quantity, cost basis, market price, heldQuantity, openIntentQuantity, acquisitionSource and workspaceId for each purchase entry. Call this to reconcile physical sealed stock before listing or opening it. Recovered components can have unknown allocated cost basis and an approximate recovery date. A hold differs from an actual opening; call spellbook_sealed_portfolio_hold_set to correct a holding mark.

spellbook_sealed_portfolio_hold_set

ChatGPT
Mark every still-sealed unit in one purchase entry as a long-term hold, or release that hold. A hold keeps physical inventory and market value but excludes those units from sealed listing. Read spellbook_sealed_portfolio before and after to check heldQuantity.

spellbook_sealed_portfolio_open

ChatGPT
Record that an exact quantity of sealed boxes or packs has already been physically opened. Use the entryId from spellbook_sealed_portfolio and read the returned counts; the same entryId and quantity safely replay after a timeout.

spellbook_sealed_portfolio_open_intent_clear

ChatGPT
Clear the plan to open every still-sealed unit in one purchase entry. Call this when spellbook_sealed_portfolio shows openIntentQuantity for stock the seller intends to keep sealed; then read the portfolio again. This preserves the units and any holding mark.

spellbook_sealed_portfolio_receive

ChatGPT
Mark one incoming sealed display purchase entry as physically received after the seller confirms its arrival. Call spellbook_sealed_portfolio first to identify the incoming entry, then read it again to confirm owned status. This preserves its holding mark and opening plan.

spellbook_sealed_portfolio_record

ChatGPT
Record one sealed acquisition the customer has already made, so the buy can be scored later against what it cost. Names the catalog boxId, the quantity, the unit price paid as a decimal string, and the acquisition date. Use it after a seller buys a box, pack or case found through spellbook_sealed_deal_board. It records a purchase that happened; it never buys anything and moves no money.

spellbook_sealed_product_offers

ChatGPT
Inspect one exact TCG product ID's sealed offers, retail references, currencies, stock and freshness. Opening EV is not intact resale value. Empty title or null computedAt can mean missing snapshot.

spellbook_sealed_recovered_component_record

ChatGPT
Record sealed packs recovered from already-opened products, without adding a new purchase or guessing their share of the parent product's cost. This bounded intake accepts the confirmed Aetherdrift Box Topper and Modern Horizons 3 Collector Booster Sample Pack products.

spellbook_sku_exact_price_lock_clear

ChatGPT
Clear one seller SKU's unprotected exact-price lock by exact printing, finish and condition. Seller-protected locks refuse agent removal. Call spellbook_sku_price_controls first to inspect protection; the saved readback confirms a successful clear with a null lock.

spellbook_sku_exact_price_lock_set

ChatGPT
Set one seller SKU's unprotected exact-price lock and return its saved readback. Identify the exact printing, finish and condition. A seller-protected lock refuses agent changes. Call spellbook_sku_price_controls first to inspect protection. Saving a lock does not publish or trigger repricing.

spellbook_sku_minimum_floor_clear

ChatGPT
Clear one seller SKU's minimum floor by exact printing, finish and condition. Returns the saved controls readback, so the agent can confirm the floor is null.

spellbook_sku_minimum_floor_set

ChatGPT
Set one seller SKU's minimum sell price and return its saved readback. Identify the exact printing, finish and condition. A floor raises computed prices up to the floor; it does not make an exact ask and does not trigger repricing.

spellbook_sku_price_controls

ChatGPT
Read one seller SKU's exact minimum floor and exact-price lock by printing, finish and condition. Returns saved values, timestamps, all-marketplaces lock scope and whether the seller protected the lock from agent changes. Call it before changing a floor or lock, then read it again after a write.

spellbook_tcg_extension_pairing

ChatGPT
Read whether this workspace has a paired TCGplayer browser extension, and get the SpellBook page where the seller pairs one. TCGplayer has no seller API, so SpellBook syncs TCGplayer listings and orders through a Chrome extension on the seller's own computer. Returns whether the account has extension access, the current session's status, when it was paired, when the extension last checked in, and its order sync state. If session is null or lastSeenAt is null, give the seller pairingPage.guideUrl to install the extension, then pairingPage.url to pair it. Call this tool again after they finish.

spellbook_tcg_listing_export

ChatGPT
Produce the CSV a person uploads to the TCGplayer portal, and mark those copies as listed in SpellBook. Call it only after spellbook_tcg_listing_preview and only once the person has said they will upload the file. Hand them the CSV and tell them plainly that SpellBook now believes these copies are listed, so the upload has to happen.

spellbook_tcg_listing_preview

ChatGPT
Show which cards in one workspace would be listed on TCGplayer, and at what price, without changing anything. TCGplayer has no server-side publish, so the real path is a CSV a person uploads to the TCGplayer portal. Call this first and show the person the candidates and the totals, then call spellbook_tcg_listing_export only once they have agreed to upload the file.

spellbook_workspace_create

ChatGPT
Create the signed-in seller's first workspace when spellbook_workspaces_list comes back empty. It makes a workspace the seller owns. A signup Store trial starts only when its flag is on and the free Seller cap is off for this workspace. When the seller already has a workspace, it returns the first one and creates nothing, so a repeated call is safe. It returns workspaceId, name, role, and created.

spellbook_workspaces_list

ChatGPT
List the authenticated customer's existing workspaces with workspaceId, name, membership role and status. Owner, admin and member roles are preserved. Discover a workspace before selecting it; this read creates no workspace or trial. When the list is empty, spellbook_workspace_create makes the first one.
