A sample answer, with every field the tool returns, is on the Norway page.

Organisation number or company name

An org_number goes straight to Brreg, which is the fastest and most predictable route. A company_name, or a phrase such as "the Norwegian oil company Equinor", first goes through a short language-model step that pulls out a clean name, and Brreg is then searched by that name. Both work. Use the number when you have it.

What the roles merge adds

A plain Brreg entity lookup does not say who runs the company. Strale makes a second call to Brreg's roles endpoint and merges in the board members, CEO, deputy chair and signatories, with their role and, for individuals, date of birth. They come back in one legal_representatives list, which saves you from reading Brreg's nested role groups yourself.

Ways to get this data

If you need only the raw entity record and are happy to write a Brreg client, calling Brreg directly is free and reasonable. Strale is for when you want the representatives merged in, search by name, or one way of calling every country.

Limits

• Sole proprietorships are not covered. Enkeltpersonforetak are not included. Query Brønnøysundregistrene directly for that entity type.
• Financial figures can be up to 12 months old. They come from annual reports. Check Brreg's accounts register for the latest filing if freshness matters.

Questions

Do I need the exact legal name?

No. A company_name goes through a name-extraction step before Brreg is searched, so reasonably close input works. An org_number is exact and skips that step.

Does this cover sole proprietorships?

No. Enkeltpersonforetak are not covered.

Is it free?

No. It costs €0.05 a call and needs a Strale API key.
