Insolvency of a British company

The British counterpart to the French legal-alerts check. The difference to know is terminological and it matters: British law distinguishes several regimes — administration, voluntary liquidation, compulsory winding-up — whose consequences for a creditor differ. The response returns the regime, not a mere flag.

What the route returns

Catalogue description, exactly as agents read it:

UK company insolvency record for credit risk and compliance screening, live from Companies House by company number: liquidation (compulsory or voluntary), administration, receivership and other cases with their dates and insolvency practitioners (name and role only, no addresses). A company with NO recorded case returns an explicit positive answer (200, aucune_procedure) — the register is authoritative, an empty record is a fact. Open Government Licence v3.0 (Companies House).

Expected identifier

British company number.

A wrongly formatted identifier returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

Price and billing

Price: $0.02. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

What this route does not do

Live query at the register: always current, but dependent on its availability. A register outage returns 503 and the call is not billed — never a degraded response.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.
