  title: Landgate SLIP Public (ArcGIS REST) Services API
  version: '12.1'
  summary: OpenAPI description of the anonymously callable ArcGIS Server REST surface of Landgate's Shared Location Information Platform (SLIP) public tier.
  description: 'Landgate does not publish an OpenAPI definition. This document is an API Evangelist

    GENERATED description of the Esri ArcGIS Server 12.1 REST surface that Landgate serves

    anonymously at https://public-services.slip.wa.gov.au/public/rest.


    Every path and operation below was probed live and returned HTTP 200 without any

    credential (see `x-evidence` on each operation, probed 2026-07-26). Nothing here is

    invented: the operations are the standard ArcGIS REST resources that this specific

    server answers, and the parameters are the ones exercised in the probes.


    The server''s own machine-readable contract remains the ArcGIS REST services directory

    (`?f=json`), which is saved verbatim in this repo as

    `openapi/landgate-slip-public-arcgis-rest-services.json` and

    `openapi/landgate-slip-public-services-folder.json`.
