# 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. ## Extract from a genuinely paid response Dated snapshot from 2026-07-29, truncated to one item per array. It is not live data. The full extract is served **free of charge** from [the samples surface](https://api.sirenic.eu/exemples/), and the schema from the OpenAPI document. ``` { "surveillance_id": "sw_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx..", "jeton": "sw_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx..", "cibles": 2, "duree_jours": 30, "expire_le": "2026-08-28T07:36:32.134Z", "canaux": { "webhook": false, "email": false, "pull": "/v1/surveillance/sw_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" }, "source": "Surveillance Sirenic — diffs quotidiens sur sources officielles (Sirene, BODACC, sanctions, AMF, Géorisques, DECP, TED)", "disclaimer": "Vérification QUOTIDIENNE : un événement est signalé au plus tard le jour ouvré suivant sa publication par la source. Les correspondances (sanctions, listes AMF) sont des rapprochements de noms à vérifier — jamais une décision.

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. ## Calling the route ``` # 1.

Keep the token returned at creation: it alone allows polling and renewal. ## Neighbouring routes - `/v1/surveillance/{jeton}/renouveler` — $0.05 (30 j) · $0.135 (90 j) · $0.50 (365 j) / entité - `/v1/entreprise/{siren}/changements` — $0.01 ## 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](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) 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.
