  "description": "Pay-per-call property-records API for Cook County, Illinois — including the City of Chicago. Look up any property by street ADDRESS or 14-digit PIN and get parcel details, recorded sales & deed history, building permits, and property-tax assessment history, joined and normalized into one answer. Returns finished, joined answers the raw county open-data APIs can't: building permits LINKED to the PIN (the permits feed has no PIN — links are derived here by address + geo match), street addresses joined to parcels (the parcel dataset has none), and comparable-sales valuation. You get the answer, not rows to query, stitch, and derive yourself. Use for real-estate due diligence, automated valuation / comparable-sales (comps), title and lien research prep, lead enrichment, and market analysis. ~1",
