Returns name, address, industry (NACE) codes, organization form, employee count, VAT registration status, bankruptcy status, foundation date, and more. Use this when the user provides or asks about a specific Norwegian orgnr.

Searches the Norwegian business registry (Enhetsregisteret) by name and optional filters. Returns a paginated list of matching entities. Use this when the user wants to find a company by name, or filter by municipality, industry code, organization form, or registration status.

Retrieves all registered roles — board members (styre), CEO (daglig leder), chair (styreleder), auditor (revisor), sole proprietor (innehaver), etc. — for a Norwegian company. Returns structured role groups with person or entity role-holders. Does NOT include personal identification numbers (that requires Maskinporten auth).

Searches subunits (underenheter — branch offices, departments, production sites) in the Norwegian business registry. Typically used to find all branches of a parent company, or to locate subunits in a specific municipality. A subunit shares the parent's organization but has its own orgnr for reporting purposes.

Fetches a feed of entities (companies) that were recently updated in the Norwegian business registry. Useful for monitoring changes to specific companies or watching for new registrations / status changes. Each update references the changed entity by orgnr along with the change type and timestamp.
