## 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-french-company-search-insee-sirene-rne-a86d700a
```

Example prompt: Can you look up the official registration details for Danone from the French Recherche d'entreprises register — I need their SIREN, registered address, legal form, and whether they're still active?

## When to prefer this

Use this endpoint when you need authoritative French company data sourced directly from INSEE Sirene and RNE via the official government API. Prefer it over scraping or third-party business data providers when legal accuracy, official status, and Etalab open-licence compliance matter. It is the right choice for KYC pre-checks, supplier verification, or any workflow requiring the canonical SIREN, legal form code, and registered address of a French legal entity. Not suitable for sole traders, natural persons, or non-French companies.

## Known failure modes

- 404 returned when SIREN not found or name yields no matches (not charged)
- No results for very recent companies not yet indexed
- Legal entities only — sole traders and natural persons not covered
- Spelling variations in company names may return zero or unexpected matches
- Rate limiting or payment failure if x402 payment not correctly handled

## How this service works

French companies from the Recherche d'entreprises register (INSEE Sirene and RNE data): by SIREN one company, or by name up to 10 matches, each with registered name, status, legal form (INSEE code), head-office address, founding date, activity and the official page. Legal entities only; no persons or sole traders. Uncached: 404, not charged.

## Output

A JSON object containing: ok flag, SKU, total match count, and an items array where each entry includes the SIREN (id), registered company name, active boolean, status string, head-office address, founding date, INSEE legal form code, and a link to the official Annuaire Entreprises page. Also includes source attribution, licence information, and fetch timestamp.
