Create a company watchlist

The most common hole in an onboarding process is checking at entry and never coming back: insolvency proceedings open after signature. This route also watches director targets, not just companies — useful when the risk is the person.

What the route returns

Catalogue description, exactly as agents read it:

Company monitoring for France: a 30, 90 or 365-day surveillance watchlist (?duree=), recurring KYB & compliance alerts. Each target checked DAILY against official sources; Ed25519-signed webhook and/or e-mail digest, always pollable. Company targets (SIREN): BODACC, status, officers, sanctions/AMF blacklist, PSAN/SGP, Seveso, new FR & EU procurement awards. Director targets (dirigeant:Name): new/ended offices. Per target (1-100) x duration: $0.05 / $0.135 / $0.50. No account, no refund.

Expected identifier

cibles parameter: 1 to 100 company numbers, or targets of the form dirigeant:Name. Plus duree=30|90|365.

A wrongly formatted identifier returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

Price and billing

Price: $0.05 (30 j) · $0.135 (90 j) · $0.50 (365 j) / entité. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

Batch billing: the cibles parameter accepts 1 to 100 comma-separated values, and the amount is the unit price times the number of values. The quote is frozen before settlement: there is no partial settlement.

The unit price additionally depends on the duree parameter, from a closed list: $0.05 (30 j), $0.135 (90 j), $0.50 (365 j). Default value: 30.

An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

No account, therefore no dashboard and no refund, no pro rata. Keep the token returned at creation: it alone allows polling and renewal.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.
