Example prompt: Can you look up Norwegian company 923609016 in the official Enhetsregisteret and tell me its legal name, registration status, registered address, and VAT number?

## When to prefer this

Choose this endpoint when you need authoritative, official Norwegian company data sourced directly from Brønnøysundregistrene/Enhetsregisteret. It is ideal for KYC, supplier verification, invoice validation, or any workflow requiring legally reliable Norwegian entity data with VAT/MVA and LEI fields in a normalized cross-European JSON schema. Prefer it over web scraping or third-party aggregators when data freshness and official provenance matter.

## Known failure modes

- Invalid or malformed organisasjonsnummer (not exactly 9 digits) returns a 400 error
- Company not found in Enhetsregisteret returns a 404 error
- Upstream Brønnøysundregistrene registry downtime may cause 503 or timeout
- Rate limiting or payment failure returns a 402 or 429 error
