How this service works
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. ~1.9M parcels, refreshed nightly, property-keyed (public records only — no personal data). No signup or API key: pay per call via the x402 protocol (USDC on Base or Solana).
Output
A normalized JSON object containing parcel details (lot size, zoning, legal description), recorded sales and deed transaction history, building permit history, and property tax assessment history for the requested Cook County parcel — sourced from the Assessor, Recorder of Deeds, and City permit portals and refreshed nightly.
Example use cases
Example prompt
“Pull the full property record for 123 N Wacker Dr, Chicago, IL — I need the parcel details, any recorded sales and deed history, building permits, and tax assessment history all in one shot.”
Technical details
Endpoint
GEThttps://api.ingest0r.com/v1/parcel/%7Bpin%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single, normalized property-data response for a Cook County or Chicago property without manually stitching together the Assessor, Recorder, and City permit portals. Ideal for real estate due diligence, comps research, title prep, or lead enrichment workflows where speed and data joining matter. Prefer over raw open-data portals when you need deed history, permits, and assessments joined in one call.
Side effects
- PIN or address not found in Cook County — parcel may be outside Cook County jurisdiction or PIN format is incorrect
- Malformed 14-digit PIN returns 400 error
- Address ambiguity (multiple parcels match) may return error or require PIN instead
- Service unavailable during nightly refresh window
- Payment failure via x402 if insufficient USDC balance or unsupported wallet
