What it can do
| Tool | What it says it does |
|---|---|
audit_claims | Audit what an agent believes about companies. Send up to 10 claims ({subject:{identifier|name|jurisdiction}, field, value}) and get, claim by claim: supported (the register says this), contradicted (it says something else, shown), stale (the register records it as FORMER, with the date it changed)… |
buy_card_package | Included. Opens a Stripe Checkout Session for one card package and returns its payment link and its session id. This tool charges nothing and produces no artefact: on the card rail the thing that taps is a human. The package's work runs only at its redeem path, after Stripe's own record says that… |
check_document | A whole document in one call: the claims that can be verified against a primary source, each answered by the door that owns it with its own signed receipt, plus one receipt over the document. Extraction is mechanical, so the claim list and the count are reproducible from your document alone —… |
check_entity | Verify a legal entity: does this company exist, under which identifier and jurisdiction, and is its registration current? Cited to open primary registers (the GLEIF LEI index and US SEC EDGAR). Returns found, ambiguous, not_found or unknown; a near name match is never reported as a match. Not… |
check_entity_file | The entity file: ONE paid answer holding everything we hold about one company: the whole picture in ONE call rather than four separate facts stitched together, at the point of signing, onboarding, paying or acquiring a counterparty. It holds identity and standing, the registered office, SIC… |
check_entity_file_ca | Canadian company lookup and Canadian federal corporation register check by nine-digit Business Number (BN) only: corporation number, BN, governing legislation, every registered name with type, current flag and effective date, the register's own status, the registered address, the MINIMUM and… |
check_entity_file_il | Israeli company lookup and company register check by company number (nine digits, with its own check digit) or by registered name, Hebrew or English: identity, corporation type, the register's own status and sub-status, description and stated purpose, incorporation date, government-company flag… |
check_figure | Submit the dated figure you are about to act on. Returns verified, stale, contradicted or unknown, cited to the publisher's own series with its as-of date. Relevant wherever a number is going onto a page, deck or decision. Not advice. Comes with an Ed25519-signed receipt covering the question, the… |
check_sanctions | Sanctions screening of a name, for whether a person or company is on a sanctions list — and which one. Reads OFAC SDN, the UN consolidated list, the EU Financial Sanctions File and the UK Sanctions List, and returns listed, mismatch, not_found or unknown. The answer names the lists that were… |
check_vat | An EU VAT number check — VAT validity, and the VAT registration behind it. Reads the official VIES service (European Commission), keyless. Returns valid, invalid or unknown — an outage is NEVER reported as invalid — with the member state, the register's own request date, and the trader identity… |
list_card_packages | Included. The one-off card packages as one machine-readable catalogue: the 11 products and their 13 prices in Australian dollars, the unit one payment buys for each SKU, what the package returns, and where the input is sent. One payment each, nothing metered, nothing subscribed. The per-call doors… |
list_series | Included. What this engine covers, the publisher and as-of date behind each series, and the no-guess rule. |
route_claim | Included. Shows which series a claim would be routed to, the value and date extracted, and the signals behind the score. Returns NO verdict — pay for check_figure when you want one. |
verify_bulk | Check a whole list in one call: a bibliography or a dependency manifest. Send items[] of {tool, input} or the citations[]/packages[] shorthand. Up to 12 items at a flat US$0.12 on this door; longer lists pay 0.016667 an item on the pack-funded HTTP door (POST /bulk, up to 25 items). Every item is… |
verify_citation | Says whether a citation can be repeated. Submit a DOI, an arXiv ID or a paper title: returns whether it exists, what it is (title, authors, year, container) and whether it has been retracted, cited to Crossref and arXiv. Optionally send what your document claims (title, authors, year, journal) and… |
verify_package | Reports on a dependency at the point of installation. Submit a package and version plus its ecosystem: returns whether that exact version exists, whether it is yanked or deprecated, and every advisory OSV lists against it. An invented version returns not_found with the real versions nearest to it… |
watch_add | Watch ONE citation or ONE package version instead of checking it once. Send kind ('citation' or 'package') and the subject (a DOI, an arXiv ID or a title; or npm:express@4.18.2). The first check is answered immediately and signed, then re-checked daily for 30 days; every real change (a retraction… |
watch_portfolio | Watch a whole list instead of one reference at a time: up to 25 citations or package versions re-checked every day for 30 days under one token. US$5 a portfolio — 20 cents a reference, under a cent a check — and the first check on every reference is answered and signed immediately. Each real… |
In its maker's words
