aid: uk-caa url: https://raw.githubusercontent.com/api-evangelist/uk-caa/refs/heads/main/apis.yml name: UK Civil Aviation Authority kind: company description: >- 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. image: https://www.caa.co.uk/apple-touch-icon.png tags: - Travel - United Kingdom - Aviation - Airline - Airports - Regulator - Government - Distribution - Consumer Protection - Open Data created: '2026-07-28' modified: '2026-07-28' specificationVersion: '0.19' apis: - aid: uk-caa:caa-consultations-api name: CAA Consultations API description: >- The Citizen Space (Delib) public consultation API deployed on the CAA's consultations domain. Two documented methods — json_search_results and json_consultation_details — return published CAA consultation activities as JSON with no API key and no signup. Versions 2.0 through 2.4 are served concurrently. Verified live 2026-07-28 (HTTP 200, JSON array). This is the only documented, publicly callable API on a caa.co.uk domain; it is the vendor's platform API, not a CAA aviation data API. humanURL: https://consultations.caa.co.uk/api/2.4/ baseURL: https://consultations.caa.co.uk/api/2.4 tags: - Consultations - Government - United Kingdom properties: - type: Documentation url: https://consultations.caa.co.uk/api/2.4/ - type: Documentation url: https://consultations.caa.co.uk/api/ - type: APIReference url: https://consultations.caa.co.uk/api/2.4/ - type: APIReference url: https://consultations.caa.co.uk/api/2.3/ - type: GettingStarted name: API v2.x Developers' Guide url: https://help.delib.net/article/350-api-v2-x-developers-guide - type: OpenAPI name: CAA Consultations API 2.4 (transcribed by API Evangelist from the published reference) url: openapi/uk-caa-consultations-api-openapi.yml - type: Overlay url: overlays/uk-caa-consultations-api-overlay.yaml - type: Examples name: Verified live json_search_results response (st=open, fields=all) url: examples/uk-caa-json-search-results-open-all.json - type: Examples name: Verified live json_consultation_details response (fields=all) url: examples/uk-caa-json-consultation-details-all.json - type: JSONSchema name: Consultation activity (derived from the transcribed OpenAPI) url: json-schema/uk-caa-activity.json - type: JSONSchema name: Term (audience, area or interest) url: json-schema/uk-caa-term.json - type: JSONSchema name: Supporting document url: json-schema/uk-caa-supporting-document.json - type: JSONSchema name: Related link url: json-schema/uk-caa-related-link.json - type: Vocabulary name: CAA consultation vocabulary derived from the full live corpus (294 activities) url: vocabulary/uk-caa-vocabulary.yml - type: Website url: https://consultations.caa.co.uk/ common: - type: AgenticAccess url: agentic-access/uk-caa-agentic-access.yml - type: VulnerabilityDisclosure url: security/uk-caa-vulnerability-disclosure.yml - type: DomainSecurity url: security/uk-caa-domain-security.yml - type: Security name: CAA Vulnerability Disclosure Policy url: https://www.caa.co.uk/website-policies/vulnerability-disclosure-policy/ - type: WellKnown url: well-known/uk-caa-well-known.yml - type: SecurityTxt name: security.txt captured verbatim 2026-07-28 url: well-known/uk-caa-security.txt - type: LLMsTxt name: CAA llms.txt (provider-published, captured verbatim) url: llms/uk-caa-llms.txt - type: LLMsTxt name: ATOL llms.txt (provider-published, captured verbatim) url: llms/uk-caa-atol-llms.txt - type: Authentication url: authentication/uk-caa-authentication.yml - type: Conventions url: conventions/uk-caa-conventions.yml - type: Lifecycle url: lifecycle/uk-caa-lifecycle.yml - type: ChangeLog name: Citizen Space API version history reconstructed from the 2.0-2.4 reference pages url: changelog/uk-caa-changelog.yml - type: Conformance url: conformance/uk-caa-conformance.yml - type: ErrorCatalog url: errors/uk-caa-problem-types.yml - type: DataModel url: data-model/uk-caa-data-model.yml - type: Vocabulary name: UK CAA consultation vocabulary — 19 workspaces, 47 audiences, 43 interests, derived from 294 live activities url: vocabulary/uk-caa-vocabulary.yml - type: Packages name: Registry search record — the CAA publishes no SDK or client library in any language url: packages/uk-caa-packages.yml - type: AgentSkill url: skills/_index.yml - type: Arazzo name: Track UK CAA consultations url: arazzo/uk-caa-track-consultations.yml - type: Website url: https://www.caa.co.uk/ - type: Documentation url: https://www.caa.co.uk/data-and-analysis/ - type: Documentation name: CAA publications (CAP documents) — the authoritative regulatory library url: https://www.caa.co.uk/publications/ - type: Pricing name: >- G-INFO forms and fees — pricing and licence terms for the UK aircraft register data product.
