What the route returns

Catalogue description, exactly as agents read it:

Norwegian company local units (underenheter, like 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. Legal persons only: a known one 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.

What this route does not do

The bulk holds only units still registered: a closed unit drops out. Legal persons only.

How you pay

Every route is paid per call, two ways, with no subscription: over x402, in USDC or EURC on the Base network, with no account and no API key; or with the API key of an account, which opens the free quota. Over x402, the first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Open today: 150 free calls a month with an account, on 123 of 129 routes (the price list says which), and pay-per-call over x402 (USDC or EURC), with no account except registry filings. Prepaid credits: card top-up is not open yet.

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.
