adjust_account_balance
ChatGPTRecord one or more account-rebalance entries in bulk (up to 1000). Each entry is a TransactionSyncDto with type=Adjustment (3) and a SIGNED amount (positive or negative). The only place a transaction may carry a negative amount. category_id and to_account_id must be null. Excluded from income/expense aggregates by default.

aggregate_transactions
ChatGPTGroup + sum transactions over a period with FX normalization. By default Transfer (type=2) and Adjustment (type=3) are excluded so income/expense numbers match the mobile UI. Set include_transfers / include_adjustments to true to include them, or set filter.type=[…] for explicit type filtering.

convert_currency
ChatGPTConvert an amount between two ISO-4217 currencies using the latest FX rates. For bulk conversion across many transactions, prefer the 'currency' parameter on aggregate_transactions.

download_receipt
ChatGPTReturns a short-lived signed URL (60 min) to download the receipt attached to a transaction. The URL points directly at Google Cloud Storage — fetch via plain HTTPS GET. Returns null if the transaction has no receipt or the file metadata is missing.

get_account_balance
ChatGPTReturns the live computed balance for one or more accounts using the same formula as the mobile UI: initial_balance + income - expense - transfers_out + transfers_in + adjustments. Each account's balance is in its own currency; pass currency to also get a converted figure per account. Pass account_ids to filter, or omit to receive every account. Set include_unassigned to surface income/expense transactions that have no account assigned (rendered as a synthetic 'Unassigned' bucket).

get_transactions
ChatGPTList transactions with rich filters (date range, type, accounts, categories, group_ids, amount range). Returns a page sorted by date desc; pass the cursor from a previous response to fetch the next page. Combining a date range with an amount range is rejected (400) — use aggregate_transactions for that intent. Filtering by group_ids resolves through the user-group-transactions junction (an M2M link, since Transaction has no direct groupId field) and uses in-memory pagination.

list_accounts
ChatGPTReturns the user's accounts (personal + shared) paginated. Personal accounts paginated server-side; shared accounts (where you're a non-owner member) paginated independently via shared_cursor. SharedItems and PersonalItems each carry their own NextCursor / HasMore — page each axis independently.

Well-known categories are returned only on the first response (when custom_cursor is null) — they're a static set, not paginated.

reconcile_account
ChatGPTBring an account's computed balance in line with an external figure (e.g. the bank app's screen) by creating a single signed adjustment entry. Computes delta = expected_balance - current_balance and posts it as a type=Adjustment transaction. Returns the previous and new balance plus the adjustment sync_id. NOT idempotent — calling twice creates two adjustments.

transfer_between_accounts
ChatGPTRecord one or more account-to-account transfers in bulk (up to 1000). Each transfer is ONE transaction with type=Transfer, AccountId=source, ToAccountId=destination, CategoryId=null. Cross-currency transfers MUST set both exchange_rate and converted_amount (positive, in destination currency); same-currency transfers MUST leave both null.

upload_receipt
ChatGPTAttach a receipt (JPEG/PNG/HEIC/WebP image or PDF) to an existing transaction. Server fetches the file from the provided HTTPS URL. Max 10MB; identical files (SHA-256) are deduplicated against the user's existing files; replaces any prior receipt on the same transaction. If the file is not yet at a public URL (e.g. it's a chat-attached photo), upload it first to a public host (Dropbox, Imgur, signed cloud-storage URL, etc.) and pass that URL.
