# Insolvency of a British company

The British counterpart to the French legal-alerts check. The difference to know is terminological and it matters: British law distinguishes several regimes — administration, voluntary liquidation, compulsory winding-up — whose consequences for a creditor differ. The response returns the regime, not a mere flag.

## What the route returns

Catalogue description, exactly as agents read it:

**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).**

## Expected identifier

British company number.

> ⚠️ 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: **$0.02**. 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.

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. Le devis, sans rien payer : la route répond 402 avec son montant
curl -i https://api.sirenic.eu/v1/eu/entreprise/GB/{company_number}/insolvabilite

# 2. L'appel réglé — le client x402 paie le devis et rejoue la requête

# 3. Ou en MCP, dans Claude Code / Cursor / un agent
claude mcp add --transport http sirenic https://api.sirenic.eu/mcp
```

## What this route does not do

**Live** query at the register: always current, but dependent on its availability. A register outage returns `503` and the call is not billed — never a degraded response.

## Neighbouring routes

- `/v1/eu/entreprise/CZ/{ico}/insolvabilite` — $0.02
- `/v1/eu/entreprise/LV/{regnr}/insolvabilite` — $0.02

## 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**
