Endpoint
POSThttps://api.x-402.online/v1/fr/etablissementsWhen to prefer
Use this endpoint when you need to verify or enrich data about a specific French company using its SIREN identifier, particularly when you need its registered headquarters address, SIRET code, legal status, and establishment footprint. Prefer this over a generic company search when you already have the SIREN and want structured, authoritative registry data for KYB, compliance, or data enrichment workflows.
Side effects
- Invalid or non-existent SIREN returns an error or empty result
- SIREN not found in the French national registry returns 404 or null data
- Missing required siren query parameter results in a 400 bad request
- Rate limiting or payment failure returns 402 or 429
- Dissolved companies may return limited or outdated establishment data
