{"jsonrpc":"2.0","id":1,"method":"tools/list"}us_auctions_search — Search live US auction lots across every source Pipeworx indexes — commercial auction houses (HiBid: ~1,900 US auctioneers, industrial liquidations, estate and equipment sales) and government surplus/seized/tax-deed sales (GovDeals, AllSurplus, PublicSurplus, Bid4Assets, IRS). Filter by free-text keyword (matched on the lot title, e.g. "forklift", "excavator", "F-150"), 2-letter state, asset_type (vehicle|equipment|realestate|electronics|other), segment (commercial|government), auction_house, max_price and closing_within_hours — or search geographically with near_zip + radius_miles ("forklifts within 50 miles of 94402"), which returns lots ordered by distance. Keyword search is full-text over the lot title AND description, so "cnc lathe" finds a lot titled "Haas TL-1" whose description says CNC lathe. Returns each lot with source, title, selling house, location, current bid, close time and a link. For what things actually SOLD for, use us_auctions_sold_comps instead.us_auctions_closing_soon — US auction lots ordered by soonest close time — the "what can I still bid on before it ends" view across commercial and government sources alike. Optionally filter by state, asset_type, segment, auction_house or keyword. Returns lots with hours remaining, current bid, location and link.us_auction_events — Upcoming US auction EVENTS — the sales themselves rather than individual lots ("Synthetic Fuels Company plant liquidation, 271 lots, Aug 28, Fremont CA"). Use this to answer "what auctions are happening near me next week" or "what is this auction house selling". Filter by state, keyword (sale title), auction_house, and a closing date range. Returns each sale with its house, location, lot count, local sale date and a link. Sale dates are the auctioneer's LOCAL calendar date — upstream publishes them without a timezone, so a precise instant is not available at the sale level; individual lot close times (us_auctions_closing_soon) are exact.us_auction_houses — Which US auction houses Pipeworx covers, and how much they currently have live — name, home state, number of open sales and total lots across them. Use to find the auctioneers active in a state or in a niche ("who runs industrial liquidations in California"), then pass the name to us_auction_events or us_auctions_search. Ranked by live lot count.us_auctions_sold_comps — Historical SOLD prices for US auction items — the final hammer price of closed lots, which no upstream site keeps but Pipeworx retains across both the commercial and government halves of the market. Use to answer "what do used forklifts actually fetch at auction" or to comp an asset before bidding. Filter by keyword (title match), asset_type, state and segment. Returns count, min/median/average/max final price, and recent examples. Only lots that closed with a recorded sale price above zero are counted — a closed lot that drew no bids is not a comp.us_auctions_coverage — Current US auction coverage: per-source active lot counts, open sale counts, retained sold comps, and when each source last refreshed. Use to gauge breadth and freshness before relying on the data.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
