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.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Landgate the way a machine reads it — 20 machine-readable artifacts across 10 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Landgate scores 40.9/100 (developing), with a separate agent-readiness read of 39/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Landgate
Each block below is one kind of artifact we hold for Landgate. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 10
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

OPEN COLLECTIONSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Landgate, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
