Unified profile of a European company

One route for eleven registers, and that is the whole point: your code need not know each one's quirks. The trade-off to accept is that a field a register does not publish stays absent — unification harmonises the shape, it does not invent missing data.

What the route returns

Catalogue description, exactly as agents read it:

European company profile by country code and national ID — official company registry data in one unified JSON schema: identity, legal form, status, creation date, head office, VAT, LEI, register link. Live: Norway, Estonia, Latvia, Belgium (KBO, NACEBEL + establishments), Czechia (ARES), Slovakia (RPO), Finland (PRH), Poland (KRS), Switzerland (Zefix, the Swiss company registry); Denmark and UK when enabled; elsewhere via GLEIF (LEI). European company data for KYB and due diligence.

Expected identifier

Two-letter ISO country code, then the NATIONAL identifier — whose format changes with every country. See the per-country pages.

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: $0.01. 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.

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.
