**APIs profiled:** 1

The UK Civil Aviation Authority (CAA) is the United Kingdom's independent aviation regulator and a public corporation of the Department for Transport. It licenses UK airlines, registers UK civil aircraft on the G-INFO register, regulates airspace and airports, economically regulates Heathrow and Gatwick, enforces UK air passenger rights, and — the part that matters most to travel distribution — runs the Air Travel Organiser's Licence (ATOL) scheme, which is the statutory gate every business selling flight-inclusive packages to UK consumers must pass through, including sellers established outside the UK. The CAA sits above the distribution chain rather than inside it: it does not distribute inventory, does not operate a GDS or NDC connection, and has no NDC posture of its own. Its API posture is thin and honest to record — there is no developer portal, no OpenAPI, and no published aviation data API. The only documented, self-serve, key-free public API on a CAA domain is the Citizen Space (Delib) consultation API at consultations.caa.co.uk/api, a vendor platform API rather than an aviation data API. The aviation surfaces that do exist — the G-INFO aircraft register search and the Check an ATOL search — are undocumented ASP.NET JSON backends whose CORS policy is locked to www.caa.co.uk and which are reCAPTCHA-gated. Bulk aviation data is delivered as CSV, PDF and XLSX files behind opaque GUID download URLs, and the full G-INFO aircraft register is a paid subscription emailed as an MS Excel file licensed for use on a single PC. Home market is the United Kingdom.
