check_listing_eligibility
ChatGPTCheck whether YOUR connected Amazon seller account can list each ASIN (ELIGIBLE / GATED / RESTRICTED / UNKNOWN). Pass the ASINs you want to verify. If the result is not_connected, tell the user to connect their Amazon seller account and stop. Verify live with get_retailer_product / check_listing_eligibility before buying.
check_skill_run
ChatGPTReserve ONE run of a LemMeBuyIt skill against your plan's daily limit. Call this exactly once at the start of a skill. If allowed is false, stop and tell the user the plan_notice message (the daily limit was reached); do not continue the skill.
find_flips
ChatGPTFind profitable resale candidates at a retailer in one call. Returns product families (variants collapsed) from the refreshed catalog ranked by ROI after marketplace fees, priced against the better of the live Amazon buy box and the Walmart cross-match (each row names the winning marketplace), with dead / parked-at-MSRP / case-pack / mismatched listings removed and a BUY or THIN call on every row, plus a coverage summary. Candidates are not gated on an on-sale flag: any price-changed item that clears the ROI screen surfaces. Set window:"today" for the daily-deals report (items refreshed today). Set retailer_id to "all" to scan across stores. To scan a whole merchandising category (e.g. every shoe/apparel or electronics store, including feed-based stores the daily scan misses), set retailer_id:"all" and pass vertical (e.g. "shoes_apparel"). On plans with paging, page the full ranked list via meta.next_cursor; the Free plan returns the top 10 rows. For ONE store, set retailer_id to that store and exhaustive:true to page its ENTIRE ROI-screened catalog (not just the top deals), served from a daily full-catalog precompute so it never times out; walmart is excluded. These are paper calls: shortlist, then verify live with get_retailer_product / check_listing_eligibility before buying. Links may be affiliate links; responses include an affiliate_disclosure.

search_promotions
ChatGPTSearch current promotions, coupons, sales, and deals across retailers. Filter by retailer, category, promotion type, coupon availability, or expiry; full-text search over titles/descriptions; cursor pagination via "after". Returns active promotions by default (set active=false to include expired/upcoming).
search_retailer_products
ChatGPTSearch and SAMPLE a retailer's catalog: text search, barcode lookups, price/discount filtering, and cursor pagination via 'after'. Returns compact items by default (~14 fields); use response_format="resale" for resale signals or "full" for everything. Per-call cap is 500 items. NOTE: this tool is for finding and sampling products, not bulk export. Paging an entire catalog one cursor at a time is slow and token-heavy.
