Data WA CKAN Action API
Landgate leads implementation of the WA Whole of Government Open Data Policy and operates data.wa.gov.au, whose catalogue runs CKAN with the standard /api/3/action surface exposed anonymously. Confirmed 2026-07-26 — status_show, package_search, package_list and organization_show all returned HTTP 200 without credentials; the catalogue holds 2,872 datasets, of which 395 are published by the Landgate organization. A DCAT JSON-LD catalog is served at /catalog.jsonld. Note honestly that the API is open but most Landgate datasets in it carry a custom Landgate licence rather than an open licence (371 of 395 are license_id custom_other; only 2 are public domain and 5 are CC non-commercial).
