Insolvency notices of a UK company

Companies House gives a company's status; The Gazette, the official journal, publishes each step of the procedure — winding-up resolution, appointment of liquidators or administrators, winding-up petition and order, creditors' notices, dividends — about 220 notices a day. Sirenic collects them every morning, day by day, and attaches them to the company number: from the feed text when it carries it, otherwise from the notice itself, deferred, at the pace the site tolerates. The response says when the stock starts and how many notices still await attachment: coverage is partial, and says so.

What the route returns

Catalogue description, exactly as agents read it:

UK company insolvency notices from The Gazette, the official journal (London, Edinburgh, Belfast; OGL v3.0), collected daily from the corporate insolvency feed (category 24): winding-up resolutions and petitions, appointment of liquidators and administrators, winding-up orders, creditors' notices, dividends — official notice code, closed-list type, date and link. What Companies House does not give. A known company with no notice gets an explicit bounded answer. No personal data.

Expected identifier

8-character Companies House company number, leading zeros included.

A wrongly formatted identifier in the path 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. A search parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

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

Never any personal data: The Gazette's OGL v3.0 excludes it — no notice text, no insolvency practitioners.

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.
