What this server can do
5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
find_chicago_comparable_sales(pin)- Recent arm's-length comparable sales (comps) in the same Cook County assessor neighborhood and property class as the given PIN, with an implied low/median/high price range — a derived, lightweight automated valuation you won't get from a raw open-data query. Costs $0.10 per call (x402, USDC) — the highest-value route; try get_free_sample first. Required: pin.
get_cook_county_parcel(pin)- Cook County, IL parcel record (address, assessor class, township, neighborhood, ward, schools, lat/lon) for a 10- or 14-digit PIN. Costs $0.01 per call (x402, USDC). Required: pin.
get_cook_county_property_dossier(pin)- Full Cook County / Chicago property dossier (parcel basics, recorded sales & deed history, building permits, property-tax assessment history, location context) for a PIN — the one-call due-diligence record. Permits are LINKED to the PIN here (the raw permit open-data has no PIN; links are derived by address + geo match), so this is a finished record you can't reproduce with raw open-data queries. Costs $0.03 per call (x402, USDC). Required: pin.
get_free_sample- FREE ($0, no payment): a fixed, representative example of every paid response shape (search, parcel, dossier, comps). Call this FIRST to validate the data structure and quality before spending anything.
search_chicago_property_by_address(address)- Resolve a Cook County / Chicago street address (full or partial) to its parcel PIN(s) — ranked candidates with address, city, ZIP, and match score. Call this FIRST when you have an address but not a PIN, then pass a returned pin to get_cook_county_parcel / get_cook_county_property_dossier / find_chicago_comparable_sales. FREE — no payment required. Required: address.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
