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.
Example use cases
Verify French supplier legitimacy
“I'm about to sign a contract with a French supplier called Bouygues Telecom — can you pull their official details from the French company register, including their SIREN, registered address, and whether they're currently active?”
Due diligence on French acquisition target
“We're doing due diligence on a French company with SIREN 552032534 — fetch me their full registration record from the official INSEE register, including legal form, founding date, and head office address.”
Find French companies by name for market research
“I'm researching the French renewable energy sector — can you search the official French business register for companies with 'éolienne' in their name and give me up to 10 matches with their status and addresses?”

Endpoint
GEThttps://api.maxwellinternational.ai/v1/gov/fr/companies?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
