  title: Sprift — valuation evidence pack
  version: 1.0.0
  summary: >-
    Resolve a UPRN to Sprift's internal property ID, then collect the price estimate,
    unified comparables, recently sold evidence and live for-sale stock.
  description: >-
    Authored by API Evangelist from Sprift's published Swagger 2.0 contract. Entirely
    read-only. Note the identifier split: the comparables operation takes the UPRN
    while the estimate, sold and for-sale operations take Sprift's internal integer
    propertyID, which is why the first step exists.
