# Detecting insolvency proceedings

Two very different questions hide behind “detect insolvency proceedings”. The first is “is this company in proceedings?” and is asked by company number. The second is “which companies entered proceedings in my area this week?” and is asked by criteria. Each has its own route, and confusing them means paying a lot for the wrong answer.

## By company: the alerts route

`/v1/entreprise/{siren}/alertes` returns the official legal-notices gazette announcements concerning one company: insolvency proceedings and related court decisions, deregistrations, business sales, grouped and most recent first. It is the check to run before contracting, and the one to re-run before granting payment terms.

## By criteria: the announcements search

`/v1/bodacc/recherche` searches **by criteria, not by company**: you pick a family of announcements (insolvency proceedings, deregistrations, sales, incorporations, accounts filings, conciliation…), a date window, and optionally a department. Up to 100 announcements, newest first, each with its company number, court, town and structured judgment.

> ⚠️ **Sole traders are excluded** from the results — their name is personal data — and their number is **counted** in the response. So you know how many announcements were withheld, which stops you reading a partial result as a complete one.

## Outside France

Three insolvency registers can be queried directly, with their national identifier:

| Country | Register | Measured volume |
| --- | --- | --- |
| Czechia | ISIR | 38,337 cases |
| Latvia | Uzņēmumu reģistrs | 17,973 proceedings |
| United Kingdom | Companies House | live, by company number |

## The reflex most often missing

Insolvency proceedings do not cancel last year's good accounts: they make them moot. That is why the default-risk score carries a **hard override** on these announcements, and why a financial analysis served without checking the legal-notices gazette is structurally optimistic. If you call only one route from this page, call the alerts one.

> Internal measurement on a calibration sample: 8 of 8 proceedings were flagged in real time by our alerts, against 0 of 8 by a competing service's financial scoring — because a batch-recomputed score has not yet seen today's announcement.

## 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. The whole catalogue is free to read in the [OpenAPI document](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**

| `/v1/bodacc/recherche` | $0.03 | Search French BODACC legal announcements by CRITERIA, not by company: pick a family (insolvency proceedings, deregistrations, sales, incorporations, accounts filings, conciliation...), a date window and optionally a department. Answers questions like: which companies entered insolvency proceedings in department 59 this week? Up to 100 announcements, newest first, each with its SIREN, court, town and structured judgment. Sole traders are excluded (their name is personal data) and counted. |

Query: /v1/eu/entreprise/CZ/45274649/insolvabilite (8-digit IČO). Every proceeding — bankruptcy (konkurs), reorganisation (reorganizace): case number, court, status, dates, its 100 most recent events with document links. Publication is compulsory by law: no proceeding is an explicit positive answer. LEGAL PERSONS ONLY: a natural person's IČO (sole trader — most Czech IČOs) is refused, never cleared. |
| `/v1/eu/entreprise/LV/{regnr}/insolvabilite` | $0.02 | Latvian company insolvency record from the official Uzņēmumu reģistrs open data (CC0, daily photo since 2008), built for credit risk and compliance screening: insolvency and legal protection proceedings in Latvia with start/end dates, resolution, court and case number.

| `/v1/eu/entreprise/GB/{company_number}/insolvabilite` | $0.02 | UK company insolvency record for credit risk and compliance screening, live from Companies House by company number: liquidation (compulsory or voluntary), administration, receivership and other cases with their dates and insolvency practitioners (name and role only, no addresses). A company with NO recorded case returns an explicit positive answer (200, aucune_procedure) — the register is authoritative, an empty record is a fact. Open Government Licence v3.0 (Companies House). |

### Can I receive these announcements automatically?

Yes, that is exactly what the watchlist is for: each target is checked daily and the alert goes out as a signed webhook or an e-mail digest.
