Technical details
Endpoint
GEThttps://api.ingest0r.com/v1/comps/:pinWhen to prefer
Use this endpoint when you already have a 14-digit Cook County PIN and need comparable sales data for property valuation, assessment appeals, real estate research, or due diligence on a specific Chicago or Cook County parcel. If you only have a street address, use the /v1/search sibling endpoint first to obtain the PIN.
Side effects
- Invalid or malformed PIN (not 14 digits) returns an error — use /v1/search first if you only have a street address
- PIN not found in Cook County records returns a not-found response
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- PIN for a property outside Cook County will not return results
