Address-level US property records from county and city open-data portals — keyless public records, no API key. Answers “when did this house last sell”, “how much did

sell for”, “who owns this property”, “what is the assessed value of

”, “property sale history”, “county assessor data for an address”. Returns the property sale history (dated transactions with price where the county publishes it), current assessed value, owner of record, parcel id (DC SSL / NYC BBL / Philadelphia OPA account / Cook County PIN / SF block-lot), land use or building class, year built, square footage, and bed/bath counts where available.
