CAA Consultations API is published by [UK Civil Aviation Authority](https://apis.io/providers/uk-caa/) on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 4 JSON Schema definitions. Tagged areas include Consultations, Government, and United Kingdom. The published artifact set on APIs.io includes API documentation, an API reference, a getting-started guide, an OpenAPI specification, and 4 JSON Schemas.

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.
