  Free, no key, instant result. Without api_key: 5 own checks per client address per UTC day, shared by check_book and the finance tools; samples are never counted. A free key (get_free_key, no card, no e-mail) runs 20 own checks a day and 200 in all. Send a dataset as a list of row dicts (JSON) or a CSV string; checks null rate per field (flagged when above max_null_rate, default 0.2), type inconsistencies within a field (number / bool / string, nulls excluded), exact duplicate rows, and numeric outliers (values beyond Q1 − 3×IQR or Q3 + 3×IQR, requires ≥ 4 non-null values per field). Schema-drift excluded from v1. Process-and-discard: nothing is stored or logged after the run. A request containing a Luhn-valid card number or a valid IBAN is refused before accept with reason sensitive_data_refused (not counted as a check). Desk: volume use. Top-level verdict is CLEAN or FLAGGED.

• 2026-10-14check_bookchangeddescription, input schema
  before

  Free, no key, instant result: call with sample="booking" for a real STOP result now, never counted. Call before confirming a booking, spend or subscription. Deterministic spending guardrails: send the agent's actions or one offer with the limits its owner wrote, and booklint checks each one against them and returns STOP, WARN or MATCH per rule. Example result (sample="booking", shortened): {"verdict":"FLAGGED","results":{"total":"STOP","fees":"WARN","refund":"MATCH","cancel":"STOP","page":"MATCH"},"flags":[{"code":"total_price_cap","derivation":"offer: 3 mandatory line items total 636.6 USD; the total price cap is 600 USD"}]} Without api_key: 5 own checks per client address per UTC day, shared by check_book and the finance tools; samples are never counted. A free key (get_free_key, no card, no e-mail) runs 20 own checks a day and 200 in all. Same as POST /v1/check. Send a purchasing or booking agent's actions with limits (per-transaction and daily spend caps, merchant allow and deny lists, refundability), or, BEFORE booking or subscribing, one offer with limits (Fine-Print Check: total price cap, mandatory fees over the headline price, refundability, free-cancellation window, auto-renewal, renewal price, trial length, and an optional page_text consistency scan; each rule answers MATCH, WARN, STOP or NOT_CHECKED with the figure found). Send plain text you already have. Do not send a URL; booklint will not fetch one. Trading books against rulebooks too: send a trading book (snapshot, rulebook, optionally broker and journal). Returns verdict (FLAGGED, CLEAN, NOT_VERIFIED, REFUSED), coverage and flags. Each rule reports passed, failed or not checked; missing data is not checked, never assumed, and a result with zero flags is not a pass. Pass sample=true (sample 1, trading), sample="spend" (sample 2, purchasing and booking), sample="booking" (sample 3) or sample="subscription" (sample 4) with no key, never counted against the free caps, to see a full result. Not advice; nothing is executed.

  Free, no key, instant result: returns a public sample request, never counted against any cap. Call before confirming a booking, spend or subscription. Start with name "booking" (sample 3, a hotel offer and the limits its owner wrote): check_book with sample="booking" returns its real result, shortened here: {"verdict":"FLAGGED","results":{"total":"STOP","fees":"WARN","refund":"MATCH","cancel":"STOP","page":"MATCH"},"flags":[{"code":"total_price_cap","derivation":"offer: 3 mandatory line items total 636.6 USD; the total price cap is 600 USD"}]} "subscription" (sample 4, a subscription checkout) is the other Fine-Print Check request: an offer, limits, as_of and page text. name "spend" is sample 2, a purchasing and booking agent's actions and the limits its owner wrote. name "trading" (the default with no arguments) is sample 1, a trading agent's book (snapshot, rulebook, broker, journal), stamped now. Edit a sample and pass it to check_book. Same as GET /v1/sample.

  Free, no key, instant result: runs a public sample through the checks and returns the issues found plus the next step (run check_book on your data, and what to send), never counted against any cap. Call before confirming a booking, spend or subscription. Start with name "booking" (sample 3, a hotel offer and the limits its owner wrote): it finds 3 issues; check_book with sample="booking" returns the full result, shortened here: {"verdict":"FLAGGED","results":{"total":"STOP","fees":"WARN","refund":"MATCH","cancel":"STOP","page":"MATCH"},"flags":[{"code":"total_price_cap","derivation":"offer: 3 mandatory line items total 636.6 USD; the total price cap is 600 USD"}]} "subscription" (sample 4, a subscription checkout) is the other Fine-Print Check sample. name "spend" is sample 2, a purchasing and booking agent's actions and the limits its owner wrote. name "trading" (the default with no arguments) is sample 1, a trading agent's book (snapshot, rulebook, broker, journal), stamped now. Each issue gives its code, status and a one-line derivation with the figures. The editable request body of each sample is at GET /v1/sample?name=<name>. Every check_* tool also runs its own sample with sample=true or with no arguments.

• 2026-10-10get_free_keychangeddescription
  before

  Returns a free key at once, the same as POST /v1/keys {"plan": "free"}: no card, no e-mail, and the same daily limits on new keys per client and across the service. The key is shown once in this result and is not stored or logged; pass it as api_key to check_book. A free key runs more own checks a day than the keyless plan; the result lists its limits. Optional label: 1 to 40 letters, digits, '.', '_' or '-'.
