Checking a customer at onboarding and never looking again is the most common hole in an onboarding process. Insolvency proceedings open after signature, not before. /v1/surveillance/creer sets up a watch on 1 to 100 targets, checked daily against official sources.

Filings in the official legal-notices gazette, status changes, officer movements, sanctions and market-authority blacklist screening, authorisations of digital-asset service providers and asset managers, Seveso classification, and new French and EU public-procurement awards.
New and ended directorships. Useful when the risk is not the company but the person running it — a director accumulating offices in distressed companies is a signal that watching the company alone will not give you.
The duration is chosen at creation time (?duree= parameter): 30, 90 or 365 days. The quote is priced on two axes — number of targets × duration — and frozen before settlement. The three unit prices appear in the routes table below; they are deliberately not repeated in this text, so that they cannot go stale in it.
Renewal (/v1/surveillance/{jeton}/renouveler) accepts any duration regardless of the original one, and remains possible until 7 days after expiry — after that the watch is purged. The cibles parameter must repeat the watched targets exactly: that is what the quote is computed from.
No account, therefore no dashboard and no refund, no pro rata. Keep the token returned at creation: it is the only way to poll and renew the watch.
If your portfolio is small and your rhythm monthly, /v1/entreprise/{siren}/changements?depuis=YYYY-MM-DD is enough: it returns announcements published since a date, and you only pay when you ask. A watch earns its price as soon as detection latency matters — because it checks every day, including the days you forget to ask.
The changes route detects new publications in the legal-notices gazette, not field-level edits of a company record: the identity stock is a monthly snapshot and keeps no history. Do not expect it to catch a silent address change.
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.

/v1/entreprise/{siren}/changements (free sample) | $0.01 | Company changes monitoring for a French company: the new official BODACC gazette announcements published SINCE a given date (?depuis=YYYY-MM-DD) — the poll endpoint for watchlist and portfolio surveillance. Returns the new announcements (insolvency, deregistration, sales, filings, changes) in reverse-chronological order. Note: detects new BODACC publications, not field-level edits of the Sirene/RNE profile (the monthly stock keeps no history). |
/v1/entreprise/{siren}/alertes (free sample) | $0.01 | Legal alerts for a French company from BODACC, the official French gazette of legal notices: insolvency proceedings (procedures collectives) and related court filings, deregistrations and business sales, grouped and most recent first. Check whether a French company is subject to collective proceedings before you contract — a due diligence, KYB and compliance signal for supplier onboarding and risk monitoring, drawn from official registry data. |
With our published Ed25519 public key. Verification takes a few lines in any language, and a worked example ships in our examples repository.
Yes, with a target of the form dirigeant:Name. The name you pass is never logged, and the watch returns only new and ended offices from official publications — no personal data beyond what the registry publishes.
The run is deferred, not discarded. This is a design rule: an unavailable source must never produce a silence that reads as “nothing to report”. Nor can a successful-but-empty run refresh the snapshot's age — that particular disarming was identified and closed.
No account to create, no key to request: the first step is free and shows you exactly what you would be buying.
