description: '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.'

  name: Hometrack Broker AVM API
  description: 'Hometrack''s own catalogue description is "This API provides access to the Broker AVM service." Twelve operations
    across two revisions (v1 and v2 paths served side by side): POST /broker/order creates a valuation order for a property,
    POST /broker/v2/order "creates the valuation order with climate data for the property", and GET operations retrieve the
    order, the order status, the valuation, the valuation input supplied at inception, and — on /internal/... paths — the
    raw valuation response "with all data, audit traces etc". The harvested request schema for a broker order is detailed
    and real: an order block with accountId, orderReference, userId and valuationType, and a valuations array carrying address
    (postcode, address, uprn), effectiveDate, a loan block (repaymentType, loanAmount, outstandingLoanAmount, additionalLoanAmount,
    remainingTerm, minimumRentalIncome, existingMortgage, instructionType) and a property block (bedrooms, receptions, propertyType,
    propertyStyle, constructionType, constructionPeriod, yearBuilt, floorArea, parking, exLocalAuthority, visibleFromRoad).
    Anonymous GET on this path returns HTTP 401.'

  description: 'A GraphQL API registered in Hometrack''s API Management catalogue with type "graphql" and path /climate/graphql,
    fronting the same climate data backend (web-uks-prod-data-api.azurewebsites.net/graphql). It is a real, listed API but
    its contract is not anonymously retrievable: the operations collection and the schema collection both returned empty arrays
    to an unauthenticated caller, so no GraphQL SDL could be harvested, and the OpenAPI export for it is a stub with servers
    and security schemes but no paths. Recorded here because absence of the schema is itself the finding.'
