## 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

```

Example prompt: Can you look up the Czech company 'Skoda Auto' in the ARES business register and give me their ICO, VAT number (DIC), registered address, and legal status?

## When to prefer this

Use this endpoint when you need authoritative Czech company identity data directly from the official ARES government register, particularly for KYC, due diligence, invoice validation, VAT cross-checking via EU VIES, or onboarding Czech business partners. Prefer this over general web search or third-party business databases when you need official ICO/DIC numbers and legal form with GDPR-compliant output.

## Known failure modes

- No matching company found for the given name or ICO — returns empty results list
- Invalid ICO format (not 8 digits) — likely returns validation error or empty results
- Limit parameter out of range (below 1 or above 10) — may return error or be clamped
- ARES upstream service unavailable — may return 5xx or timeout
- Stale cache (up to 24h old) — data may not reflect very recent registry changes

## How this service works

Official Czech business register lookup via ARES (Ministry of Finance, ares.gov.cz). Query: ?q=skoda or ?q=00177041 (company name or 8-digit ICO), optional limit (1-10). Returns ICO, DIC (CZ VAT number, cross-checkable in EU VIES), legal form, registered address, NACE activity codes, per-register status (commercial, trade, VAT) and creation date. Company data only, personal data stripped (GDPR). 24h cache.

## Output

Returns a list of matching Czech companies (up to the specified limit) from ARES, each with: ICO (company ID), DIC (Czech VAT number, CZ-prefixed for EU VIES cross-check), legal form, full registered address, NACE economic activity codes, per-register status (commercial register, trade license, VAT), and company creation date. Personal data is stripped for GDPR compliance. Data is cached for 24 hours.
