Landgate
Landgate is the Western Australian Land Information Authority — the WA government agency that maintains the state land titles register, values every rateable property in Western Australia, and curates the state's foundational location data (cadastre, tenure, property addresses, sales evidence, imagery, elevation, geographic names). In the Australian real estate value chain Landgate sits underneath the listing portals (REA Group's realestate.com.au and Domain) and underneath PEXA's electronic conveyancing rail as the authoritative source of the public land record for WA; since 2019 the automated land titling and registry operations have been operated under a commercial services arrangement while Landgate retains the Registrar of Titles function and the data custodianship. Its API posture is genuinely split and should not be overstated — a real, anonymously callable public surface exists (the SLIP Shared Location Information Platform ArcGIS REST directory plus OGC WMS/WFS services, and the Data WA CKAN Action API that Landgate operates for the whole WA public sector), while the richer registry and subscription data sits behind SLIP subscription, transaction, publication, broker, distributor and value-added-reseller licences that must be signed and, for bulk downloads, behind a MyLandgate account login. There is no developer portal, no published OpenAPI, no API key self-service, and no RESO involvement of any kind — RESO is a North American MLS standard and is absent from this Australian government registry.
Landgate publishes 9 APIs on the APIs.io network, including Datasets API, Discovery API, Organizations API, and 6 more. Tagged areas include Real-Estate, Australia, Land Registry, Title, and Valuation.
Landgate’s developer surface includes documentation, pricing, support, developer portal, authentication, changelog, engineering blog, and 26 more developer resources.
