11 tools, verified live

Pulled straight from the server with tools/list on 2026-10-17.
submit_directive

Submit one Beancount directive (open, transaction, close, balance, price, note, document — any type). Paid, except your first 20 accepted writes per registered key, which are free (this specific tool only — submit_batch is always paid, even for your first call). Call with no payment_header first: if free writes remain, this succeeds immediately; otherwise you'll get price/a

validate_directive

Free dry-run: parse+book text against your full history without persisting or charging anything. Still requires a valid signature (identity/replay protection is not a billing concern).

submit_batch

Submit up to 1000 directives atomically — all persist together or none do. Priced 10x a single write, regardless of batch size within the cap. Always paid — the free-trial allowance (see submit_directive) applies to single writes only, never to batches, even if you haven't used any free writes yet. Paid.

list_directives

List raw directives (optionally filtered by account/date range). No booking involved — cheapest paid tool. `since`/`until` are ISO date strings (YYYY-MM-DD). Your first 2 calls per registered key are free (independent of the write/accounts/report allowances — see list_accounts, get_balance_sheet).

list_accounts

List all opened accounts with their currency constraints and booking method. No booking pass involved. Your first 2 calls per registered key are free (a separate allowance from list_directives' and the report tier's — see those tools).

get_account_balance

Balance of a single account. Settles at the same fixed price whether the account exists or not — an "unknown account" answer is still a valid, billable response (no per-error pricing discount). No free-trial allowance for this specific tool, unlike list_directives (same price, but list_directives has 2 free calls and this doesn't) — the free tier applies to browsing (list_d

export_ledger

Export the full ledger as literal Beancount text — a portable snapshot for fava/bean-report/etc., not the live store. Shares a combined free allowance of 2 with get_balance_sheet, get_income_statement, and get_trial_balance (the "report tier") — not 2 free calls for each of those four separately.

get_balance_sheet

Full realize() balance sheet — often served from cache. Settles at the same fixed price regardless of cache hit/miss. Shares a combined free allowance of 2 with export_ledger, get_income_statement, and get_trial_balance (the "report tier") — not 2 free calls each.

get_income_statement

Income statement, period-scoped by since/until (ISO date strings, both optional — omitted means whole history). Always books full history first, then clamps the output to the requested period (never filters input dates — see reports.py for why). Shares a combined free allowance of 2 with export_ledger, get_balance_sheet, and get_trial_balance (the "report tier") — not 2 f

get_trial_balance

Trial balance, period-scoped same as income statement — same underlying compute, priced and audited as its own resource. Shares a combined free allowance of 2 with export_ledger, get_balance_sheet, and get_income_statement (the "report tier") — not 2 free calls each.

register

Generate a new Ed25519 keypair for ledger identity. Returns the private key exactly once — it is never stored server-side and cannot be recovered if lost. This is a SEPARATE keypair from whatever wallet you use to authorize x402 payments (payment auth and ledger identity are two independent signing domains — see payments.py).
