How this service works
Verify whether a legal entity exists and is currently registered, from open primary registers: the GLEIF LEI index, US SEC EDGAR and the Australian Business Register (ABN, ACN, GST, status). Call it before naming a company in a contract, invoice or filing, or when you need an identifier (ABN, ACN, LEI, CIK) for a company you know only by name. Returns found, ambiguous, not_found or unknown, cited to the register with its retrieval time. A near name match is never reported as a match.
Output
Returns a status of found, ambiguous, not_found, or unknown for the queried entity, along with any official identifiers found (ABN, ACN, LEI, CIK), the current registration status, the source register that was queried, and the timestamp of when the data was retrieved. Near-name matches are never reported as confirmed matches.
Example use cases
Pre-contract company verification
“I'm about to sign a vendor agreement with a company called 'Nexus Dynamics Inc' — can you check if they're actually a registered legal entity and get me their LEI or CIK before I proceed?”
Invoice ABN lookup for Australian supplier
“I need to issue an invoice to 'BlueWave Energy Pty Ltd' but I don't have their ABN — can you look them up in the Australian Business Register and confirm they're currently registered?”
Due diligence on potential acquisition target
“We're considering acquiring a company called 'Meridian Capital Group' — can you verify they exist as a registered legal entity and pull any official identifiers like their LEI or SEC CIK from the primary registers?”
Technical details
Endpoint
POSThttps://agents.factstamp.dev/entity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, cited verification of a legal entity's existence and registration status from official primary registers (GLEIF, SEC EDGAR, Australian Business Register) — especially before executing contracts, invoices, or regulatory filings. Prefer this over general web search or business data aggregators when you need a definitive registered/not-registered answer with a source citation and retrieval timestamp, and when you specifically need official identifiers like ABN, ACN, LEI, or SEC CIK.
Side effects
- ambiguous: multiple entities match the name, requiring more specificity
- not_found: no matching entity found in any of the three registers
- unknown: registers were queried but a definitive answer could not be determined
- payment failure: x402 payment not accepted or insufficient balance
- malformed input: company name too vague or missing required fields
