Hometrack
Hometrack is a United Kingdom property data, valuation and risk-decisioning company, founded in 1999 and now part of Houseful — the Silver Lake-owned group that also owns Zoopla, PrimeLocation, Alto and Jupix. It launched its automated valuation model in 2002 and says it now runs more than 50 million valuations a year, that 18 of the top 20 UK mortgage lenders use its AVM in their origination processes, and that it was the first AVM accredited by Moody's, Standard & Poor's and Fitch. It is a founding member of the European AVM Alliance. In the UK value chain it does not sit on the listings side at all: with no MLS in this market, residential listings are controlled by Rightmove and Zoopla and reach them through agency CRM software, while Hometrack sits on the lending and risk side — valuation, comparables, climate and property risk data, surveyor allocation and case management for mortgage lenders, surveyors, brokers, housing associations and investors. Its API posture is unusually revealing and must be stated in two halves. The developer surface is real and genuinely public: an Azure API Management developer portal at developer.hometrack.com is served anonymously, its data plane answers unauthenticated requests, and six APIs — a Valuation API, a Broker AVM API, a Property Risk Hub core client API, a Climate API, a Climate GraphQL API and an internal-facing public API — are listed there with full operation and schema metadata, from which six OpenAPI 3.0.1 documents were harvested. The access gate, however, is commercial: the portal states plainly that "to interact with any of our APIs you will need to have a valid API Key for that respective product. If you do not yet have an API Key, please contact us", and the gateway at api.hometrack.com answers anonymous calls with HTTP 401 "Unauthorized. Access token is missing or invalid." Authentication is OAuth 2.0 client credentials through Auth0 (hometrack-prod.eu.auth0.com) against the audience https://api.hometrack.com, with documented scopes read:valuations and write:valuations. So: contracts are readable by anyone, data is reachable by nobody without a Hometrack commercial agreement. There is no RESO Web API or Data Dictionary certification and no OData $metadata anywhere in Hometrack's stack — RESO is a North American NAR/MLS construct and the UK has no MLS to certify against. Notably, Hometrack's Climate API keys every property off the UPRN, the Unique Property Reference Number issued by GeoPlace and distributed by Ordnance Survey: the UK does have a universal property identifier, it just comes from government rather than from a real-estate standards body. Hometrack itself publishes no open data — the open UK property layer is HM Land Registry Price Paid and Ordnance Survey, not Hometrack.
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 Hometrack the way a machine reads it — 28 machine-readable artifacts across 6 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 — Hometrack scores 43.8/100 (developing), with a separate agent-readiness read of 39/100 (agent ready). 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 Hometrack
Each block below is one kind of artifact we hold for Hometrack. 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 18
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 Hometrack, 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.
