## 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 17711-company-registry-check-d33c2539 -d '<json body>'
```

Example prompt: Can you verify that Mistral AI is a legitimately registered company — check their VAT number FR22424761419 and tell me their registry status and company directors?

## When to prefer this

Use this endpoint when you need structured KYB (Know Your Business) verification for EU or internationally registered companies, especially when you need VAT validation via VIES, LEI lookups, or official registry status and director data. Prefer this over generic company profile endpoints when compliance, VAT validity, or legal entity verification is the primary goal rather than marketing or contact enrichment.

## Known failure modes

- Company not found in any registry — returns empty or null result
- Invalid VAT number format causes VIES lookup failure
- LEI not found in GLEIF database
- Country not supported for registry lookup
- Rate limit or payment failure returns 402 or 429 error
- Stale cached data returned if max_age_seconds not set to 0

## How this service works
