About this API
Bolagsverket (Sweden's companies registration office) offers a free 'Värdefulla datamängder' (Valuable Datasets) API under the EU's valuable-datasets directive. It returns Swedish company information — organization number, name, SNI activity codes, legal form, digitally filed annual reports, and document lists and files — plus data from Statistics Sweden (SCB). The API is REST/JSON and requires OAuth2 authorization (registration in the developer portal; the token endpoint is portal.api.bolagsverket.se/oauth2/token), with a 60 requests/minute limit. Use is free and requires no agreement.
Frequently asked questions

What data does this API return?
Swedish company information — organization number, name, SNI activity codes, legal form, annual reports and documents — plus statistical data from Statistics Sweden (SCB).
Can this API be called directly from a browser?
No — the OAuth2 flow and client credentials require server-side calls to avoid exposing the credentials in frontend code.
