Returns listings with source-reported sale results, auction status, vehicle specs including mileage and mileage_unit when known, condition details, modifications, known flaws, and source URLs. Buyer-premium treatment is not normalized, so use the source URL when that distinction matters. All filters are optional; narrow by make/model, exact VIN, seller_username, keyword, year, price, status, or source as needed. For sequential result sets, use pagination=cursor and pass each next_cursor to the following request; this avoids exact counts and deep offsets.
