{"jsonrpc":"2.0","id":1,"method":"tools/list"}bigiron_search — Search active US ag/construction/livestock/transportation equipment auctions on bigiron.com — a national online timed-auction platform. Returns live listings with current bid, Buy-It-Now asking price (if offered — NOT a sold price), make/model/year, seller, location and auction close time. Sourced from bigiron.com/Search.bigiron_sold_search — Search CONFIRMED-SOLD equipment lots on bigiron.com for comps — title, make/model/year, quantity, seller, location and close date for lots that actually sold. IMPORTANT: bigiron.com does not expose the realized hammer price in this page shape (verified: 0/100 sampled sold lots carry a nonzero price field, even with 60+ bids) — final_price is always null with an explanatory note; num_bids is the closest available demand signal. Use bigiron_search for current asking prices instead. Sourced from bigiron.com/Search?filter=Sold.bigiron_lot_detail — Full detail for one bigiron.com lot by its URL slug: description, sale status, bid count, make/model/year, seller, location, category and (for active lots) current bid / Buy-It-Now price. Slugs come from bigiron_search or bigiron_sold_search result urls (the part after /Lots/). Sourced from bigiron.com/Lots/{slug}.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
