Example prompt: Can you look up 'Nokia' in the Finnish business registry and show me its Y-tunnus, company form, trade-register status, and registered address?

## When to prefer this

Use this endpoint when you need authoritative, government-sourced information about Finnish companies, including their Y-tunnus (Business ID), legal form, and registry status. It is the canonical source for Finnish business entity verification, complementing UK Companies House or LEI lookups for Finland-specific due diligence, KYC, or supplier verification tasks.

## Known failure modes

- No results found for the given company name — name may be misspelled or the company may not be registered in Finland
- Name query too short (minimum 2 characters) or too long (maximum 120 characters)
- Limit parameter out of range (must be 1–25)
- Upstream PRH/YTJ data service temporarily unavailable
- Rate limiting or payment failure due to x402 protocol issues
