## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability finnish-company-registry-lookup-prh-ytj-a4581a45
```

Example prompt: Can you look up the Finnish company with business ID 0112038-9 in the official PRH/YTJ registry and tell me its legal name, current status, registered address, and main business activity?

## When to prefer this

Use this endpoint when you need authoritative, official company data for Finnish-registered entities specifically. It is preferred over generic web searches when legal accuracy matters — e.g. compliance checks, supplier onboarding, due diligence, or contract preparation. It shares a consistent schema with sibling endpoints for other countries (UK, Belgium, Czech Republic, Norway, France), making it ideal for multi-country workflows.

## Known failure modes

- No matching company found — returns count:0 and empty companies array with a note
- Invalid or malformed Y-tunnus format — may return zero results or an error
- Company name query with multiple matches — returns multiple records requiring disambiguation
- Registry temporarily unavailable — upstream PRH/YTJ outage may cause request failure
- Query string exceeds 200 character limit — validation error

## How this service works

Finnish company lookup in the official PRH/YTJ Business Information System by business ID (Y-tunnus) or company name. Returns legal name, status, company form, registration date, address, main business line and website in a schema shared across countries.

## Output

Returns a JSON object containing the ISO country code (FI), registry name (PRH/YTJ), the echoed query, a count of matched companies, and an array of company records each with: current legal name, normalized status (active/inactive/unknown), legal form, founding date, registered address (street, postal code, city, country code), business activities, and website URL.
