  title: Data WA CKAN Action API (operated by Landgate) Organizations API
  version: '3'
  summary: OpenAPI description of the anonymously callable CKAN Action API behind data.wa.gov.au, the WA whole-of-government open data catalogue Landgate operates.
  description: 'Landgate leads implementation of the WA Whole of Government Open Data Policy and operates

    data.wa.gov.au. Its catalogue runs CKAN, whose standard `/api/3/action/*` surface is

    exposed anonymously. CKAN publishes no OpenAPI, so this is an API Evangelist GENERATED

    description of the actions that this specific deployment answers.


    Every operation below was probed live on 2026-07-26 and returned HTTP 200 with

    `"success": true` and no credential (see `x-evidence`). Only actions that were actually

    exercised are described — the CKAN action surface is larger, and `helpShow` is the

    server''s own machine-readable parameter reference for any action.


    Scale observed on 2026-07-26: 2,872 datasets in the catalogue, 395 published by the

    `landgate` organization. Licensing is mixed and should not be assumed open — 371 of the

    395 Landgate datasets carry `license_id: custom_other`.
