## 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 sirenic-estonian-company-registry-lookup-743fb3a5
```

Example prompt: Can you look up Estonian company 12417834 in the official Äriregister and tell me its legal name, current status, registered office, and when it was incorporated?

## When to prefer this

Choose this endpoint when you specifically need official Estonian company data identified by an 8-digit registrikood from the Äriregister. It is the authoritative source for Estonian legal entity verification, KYB workflows, supplier onboarding, and contract counterparty checks involving Estonian companies. Prefer it over generic web search when you need structured, normalized, legally authoritative data. Use the sibling EU VAT validation endpoint if you only have a VAT number rather than a registrikood.

## Known failure modes

- Invalid registrikood format (not exactly 8 digits) returns a validation error
- Unknown registrikood (not found in the register) returns a 404-equivalent response
- Payment not provided or insufficient USDC triggers an x402 payment-required error
- Estonian register temporarily unavailable causes a gateway or upstream error
- Rate limiting if too many requests are made in quick succession
