Profile of a Norwegian company

695,579 Norwegian legal persons are served from our copy of the central register; the sole proprietorships and estates it also holds, whose profile is not served, are not counted. The Norwegian particularity lies elsewhere: it is the only country where we serve both an identity copy and an event journal with its own notion of freshness: see the events route.

What the route returns

Catalogue description, exactly as agents read it:

Official Norwegian company registry lookup (Brønnøysundregistrene, Enhetsregisteret, BRREG open data, NLOD). Query: /v1/eu/entreprise/NO/923609016 (9-digit organisasjonsnummer). Returns legal name, legal form, status, incorporation date, registered office, VAT/MVA and LEI. Legal persons only: a sole proprietorship (ENK), an estate (KBO, BO) or a form not recognised as a legal person returns 404, not billed. Same unified JSON schema as every Sirenic European profile.

Expected identifier

Norwegian organisation number, 9 digits.

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.

What this route does not do

Served from a dated local copy. The response carries the snapshot date: read it, because that is what tells you the information's worth, not the date of your call. Legal persons only: a sole proprietorship (ENK), a registered individual (PERS, TVAM) or an estate named after a person (KBO, BO), whose name is a civil name, or a form not recognised as a legal person returns 404, not billed.

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.
