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.
Hometrack publishes 18 API contracts indexed on the APIs.io network, including Authentication API, Brands API, Broker API, and 15 more. Tagged areas include Real Estate, United Kingdom, PropTech, Valuation, and AVM.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Consumer Lending Licensing (UK, US, Canada credit licence registers) | undeclared | - | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
