Search a European company

The European gateway, and the route that best explains our split between local copies and live queries: Norway, Estonia, Latvia and Spain answer from our copies; Czechia, Slovakia, Finland, Poland and Switzerland are queried at source. Beyond that, coverage goes through the global Legal Entity Identifier.

What the route returns

Catalogue description, exactly as agents read it:

European company search across official registers: company lookup by name, returning European company data in one unified schema. Norway, Estonia, Latvia and Spain (BORME base, hoja key) are served from local copies; Czechia, Slovakia, Finland, Poland and Switzerland are queried live; Denmark and UK when enabled; plus worldwide GLEIF (LEI) coverage of financial entities and large groups. Top 10 matches with country, national ID, status and a score_confiance (0-1 match confidence).

Expected identifier

None: a name, plus an optional pays filter as a two-letter ISO code.

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: $0.003. 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

Germany and the Netherlands are out of scope for this search. Legal Entity Identifier coverage gives financial entities and large groups, not the small local company.

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.
