Local units of a Norwegian company

In Norway every establishment (underenhet) carries its own organisation number and points to its company — the exact counterpart of the French SIRET. The national bulk holds 863,600 of them, reloaded every morning. The route serves a company's units with their activity, their published headcount (the register says whether it recorded one: zero is a published nil headcount, null an unrecorded one), their addresses and dates, plus the unit count and cumulative headcount. A known company with no unit gets an explicit positive answer: the bulk is the complete national snapshot.

What the route returns

Catalogue description, exactly as agents read it:

Norwegian company local units (underenheter, the equivalent of SIRET establishments) from the official Enhetsregisteret (Brønnøysundregistrene, NLOD 2.0), refreshed daily from the national bulk: each unit's own 9-digit orgnr, name, industry code (NACE-NO) and auxiliary activity, published headcount, location and postal addresses, registration and ownership-change dates, VAT status, plus unit count and cumulative headcount. A known legal person with no unit gets an explicit positive answer.

Expected identifier

9-digit Norwegian organisation number of the company.

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.
