## 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 french-company-lookup-by-name-or-siren-siret-247fcbf2 -d '<json body>'
```

Example prompt: Can you look up the French company 'Carrefour SA' and tell me its SIREN number, registered headquarters address, current legal status, NAF code, and who its officers are?

## When to prefer this

Use this endpoint when you need to verify or enrich data about a French company registered in France, especially when you have either the company name or SIREN/SIRET number. Prefer this over generic web search when you need structured, authoritative registry data including officer lists, NAF codes, and legal status for KYB, due diligence, or business verification workflows.

## Known failure modes

- Company not found — returns empty results or 404 if the name or SIREN/SIRET does not match any registered entity
- Ambiguous name query — multiple companies returned when searching by name, requiring refinement
- Invalid SIREN/SIRET format — returns an error if the identifier does not conform to expected numeric format
- Payment failure — HTTP 402 if USDC payment is not completed before the request
- Rate limiting — HTTP 429 if too many requests are made in a short period

## Output

Returns structured data about the French company including its SIREN/SIRET identifiers, NAF sector code, registered headquarters address, current legal status (active/ceased), and a list of officers (directors, executives).
