Cook County / Chicago, Illinois property records for AI agents: resolve a street address to a parcel PIN (free), then fetch parcel records, a full property dossier (recorded sales & deed history, building permits, property-tax assessment history), or comparable sales with an implied valuation range.
These are joined, derived answers the raw county open data can't return — permits are linked to PINs here (the city permit feed has no PIN field), addresses are joined to parcels, and comps are arm's-length filtered. ~1.9M parcels, refreshed nightly. Public records only — no owner or occupant personal data.
