## 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 strale-kyb-essentials-finland-8c4bb298 -d '<json body>'
```

Example prompt: Can you pull the official registry details for Finnish company with business ID 1234567-8 — I need to verify they're active and get their registered address and business form?

## When to prefer this

Use this endpoint when you need authoritative, registry-sourced KYB data specifically for Finnish companies identified by their Y-tunnus (business ID). Prefer it over generic company search APIs when you need cryptographically audited results suitable for compliance workflows, or when operating in a multi-country KYB pipeline that handles Finland as one jurisdiction among many.

## Known failure modes

- Invalid or malformed Y-tunnus format returns a validation error
- Business ID not found in the Finnish Trade Register returns a not-found response
- Dissolved or deregistered companies may return limited or historical data only
- Transient connectivity issues with the upstream Trade Register may cause timeouts

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns structured company data from the Finnish Trade Register including company name, legal form, registration status, registered address, industry code, founding date, and an audit record with a cryptographic chain hash for tamper-evident logging.
