Example prompt: Can you check the official Gazette insolvency notices for UK company number SC540982 — I want to know if there are any winding-up orders, liquidator appointments, or other insolvency events on record?

## When to prefer this

Choose this endpoint when you need official, structured UK corporate insolvency data sourced directly from The Gazette's authoritative feed — covering events that Companies House itself does not surface. It gives a bounded, explicit answer even when no notices exist, making it safe for automated due diligence workflows. Prefer it over web scraping or Companies House API calls when you need Gazette-specific notice types (winding-up, administration, creditors, dividends) with canonical notice codes and direct source links.

## Known failure modes

- 404 with payment cancelled if the company number is not recognised by Companies House
- 200 with aucune_annonce: true if the company exists but has no insolvency notices (partial coverage since stock start date)
- Malformed company number (missing leading zeros or invalid prefix) returns error
- Coverage is partial — notices only from the daily corporate insolvency feed (category 24) since the stock start date

## How this service works

UK company insolvency notices from The Gazette, the official journal (London, Edinburgh, Belfast; OGL v3.0), collected daily from the corporate insolvency feed (category 24): winding-up resolutions and petitions, appointment of liquidators and administrators, winding-up orders, creditors' notices, dividends — official notice code, closed-list type, date and link. What Companies House does not give. A known company with no notice gets an explicit bounded answer. No personal data.

## Output

A list of official insolvency notices from The Gazette for the specified company, each including notice type (e.g. winding-up petition, liquidator appointment, creditors notice, dividend), official notice code, date, and a direct link to the Gazette notice. If the company is known but has no notices, returns a bounded 200 response with aucune_annonce: true. If the company number is unrecognised, returns a 404 with payment cancelled.
