## 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 maxwell-x402-czech-ares-company-lookup-1ab1e523
```

Example prompt: Can you look up the Czech company Skoda Auto in the ARES register and tell me its official registered name, legal form, registration status, and registered address?

## When to prefer this

Choose this endpoint when you need authoritative, official company-level facts (name, status, legal form, address) for a Czech entity from the government ARES register. Prefer it over third-party business data providers when official sourcing and free reuse with attribution are required. Use sibling endpoints for Canadian, Brazilian, or German company lookups.

## Known failure modes

- 404 returned if company ID not yet cached (free, record fetched within ~1 minute — retry shortly after)
- Invalid or non-existent IČO returns not-found response
- No director or shareholder data is returned (company-level facts only)
- Search terms that are too generic may not resolve to a unique company

## How this service works

One company from Czechia's ARES register: registered name, status, legal form, registered address and the official register link (company-level facts only; no directors or shareholders). An id or search not yet cached answers 404, not charged, and is fetched within about a minute.

## Output

A JSON object containing the company's official registered name, current status, legal form code, registered address, source (ARES), country (Czechia), and a link to the official ARES register entry. Returns 404 (not charged) if the ID is not yet cached, with the record being fetched within approximately one minute.
