Sirenic
GET https://api.sirenic.eu/v1/kyb/batch
Batch KYB and bulk company lookup for 2 to 100 French companies in one call (comma-separated sirens): full KYB files with commercial-court decisions (Judilibre) and per-block provenance (official register, as-of date), for due diligence and compliance; or vue=synthese, one line per SIREN for a supplier list. Billed $0.105 per company (30% off the $0.15 unit price), quoted from the SIREN count. A SIREN with no diffusible company is returned as trouve=false and billed as one lookup.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
