How this service works

Output
Returns a registry-backed company record including: verified legal name, SIREN number, NAF/APE activity code, headcount bracket, registered headquarters address, and current legal status (active/closed).
Example use cases
CRM row completion for sales team
“We just imported a batch of French leads into our CRM and many rows only have the company name. Can you fill in the SIREN, legal status, headquarters address, and activity code for 'Criteo SA'?”
Verify a French supplier before onboarding
“Before we sign a contract with 'BlaBlaCar', can you check if they're still legally active, get their official registered address, and confirm their SIREN number?”
Research a French competitor's profile
“I'm doing competitive research — can you pull the official registry details for the company at blablacar.fr, including their headcount bracket, activity code, and legal identity?”
Technical details
Endpoint
POSThttps://api.x-402.online/v1/fr/enrich?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official, registry-backed French company data rather than scraped or user-submitted information. It is ideal for CRM enrichment, supplier onboarding verification, B2B lead qualification, and any workflow requiring verified legal identity for French entities. Prefer this over generic web search when you need structured, authoritative fields like SIREN, NAF code, or legal status.
Side effects
- Company not found in French registry — returns empty or 404 if name/SIREN/domain is unrecognized
- Ambiguous name matches multiple companies — may return the most likely match or require disambiguation
- SIREN number malformed or invalid — returns validation error
- Company recently created and not yet indexed — data may be missing
- Website domain not associated with any registered entity — no result returned
