## When to prefer this

Use this endpoint when you need to search for property or address records in Cook County (Chicago), Illinois by a street address string. It is ideal for real estate research, property lookups, or resolving partial addresses to full property records. Prefer this over general geocoding APIs when you specifically need Cook County property-level data accessible via pay-per-call micropayment.

## Known failure modes

- Query string shorter than 4 characters may be rejected or return no results
- No matching addresses found for the given query
- Payment failure due to insufficient USDC balance (x402 protocol)
- Invalid or malformed address string returns empty result set
- Rate limiting or authentication errors if payment header is missing

## Output

A list of matching address or property records corresponding to the submitted street address or partial address query, likely including parcel details, owner info, or location data relevant to Cook County properties.
