## What it does

This skill connects an agent to the public Brønnøysundregistrene API. It supports company searches by name, organization form, NACE industry code, municipality, postal code, employee count, and registration dates. Queries can also filter bankruptcy, dissolution, and VAT registration, or fetch one record by organisasjonsnummer.

The skill covers endpoints for sub-entities, organization forms, and recent registry changes. For larger datasets, it points to JSON, CSV, and Excel downloads. Public API access needs no authentication, while heavy traffic may be rate-limited.

A single query returns at most 10,000 results. Use the bulk downloads for a complete dataset.
