Example prompt: Can you look up the company details for Nokia from the Finnish PRH registry — I need their business ID, VAT number, address, and registration status.

## When to prefer this

Use this endpoint when you need official Finnish company registration data from the PRH, including VAT numbers, business types, and company status. Prefer this over general web search when you need structured, authoritative Finnish corporate registry data. Use the business_id parameter when you have the Y-tunnus for precise lookup, or company_name for fuzzy search by name.

## Known failure modes

- Invalid or malformed Business ID format returns an error
- Company not found in PRH registry returns empty or not-found response
- Ambiguous company name may return multiple or no results
- Network timeout or upstream PRH API unavailability causes failure
- Non-Finnish company queried returns no results
