What it does

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.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/30355.json for the price and payment options.
Pay. Call GET https://api.sirenic.eu/v1/kyb/batch. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
