Bidsquare Auction Lot Listings Scraper Features

• Extracts every lot across Bidsquare's live/upcoming calendar and its closed archive — not just the handful of items shown on the auction summary page
• Returns estimate ranges, buyer's premium, and hammer prices for sold lots, even on auction houses that hide bidding activity behind a login wall
• Captures auction-level context on every row — auction house, auction title, sale window, and location — so a lot never arrives orphaned from its sale
• Pulls full-size photo sets per lot, deduplicated to the actual gallery for that item
• Picks up where it left off on large runs via a resume cursor, at no extra charge for records you already have

Who Uses This?

• Appraisers — build comparables from closed hammer prices instead of guessing at fair market value
• Galleries and dealers — track what's moving through regional auction houses in a given category before consigning or bidding
• Estate and trust valuers — pull documented sale results across multiple houses for a single valuation file
• Collectors and researchers — watch specific categories (fine art, Asian works, decorative arts, jewelry) across the full member-house roster instead of checking 250 sites by hand

How Bidsquare Auction Lot Listings Scraper Works

1. Give it a maxItems limit — or leave the default and let it run against the full calendar.
2. It works through Bidsquare's live/upcoming auctions and its closed archive, following each auction house's full lot catalog rather than the abbreviated preview shown on the summary page.
3. Each lot lands in your dataset with its own fields plus the auction it belongs to, ready to filter, join, or export.

estimate_high	Number	High end of the pre-sale estimate.
currency	String	Currency of all price fields (USD on Bidsquare).
starting_bid	Number	Opening bid, where the auction house makes it public.
current_bid	Number	Current bid on a live/upcoming lot, where the auction house makes it public.
bid_count	Integer	Number of bids placed so far, where public.
hammer_price	Number	Final sale price for a closed/sold lot.

A handful of these fields are auction-house-dependent rather than Bidsquare-wide — bidding activity and provenance are public on some houses and gated behind login on others. That's the source, not a gap in the data you get from the fields it does expose.

Resuming a large crawl

Every run emits a resumeCursor in its Output. If a large crawl stops before it finishes — because it hit maxItems, your spend cap (maxTotalChargeUsd), or was aborted — start a new run with the same input plus that resumeCursor to continue from where it left off. The crawl resumes from the queued work the previous run didn't reach.

• You are not re-charged for records the earlier run already delivered.
• Resume within your account's run-retention window — on the free tier, roughly your 10 most recent runs. Once the source run is pruned, its resumeCursor is no longer valid.
• resumeCursor is opaque — supply it unmodified.

FAQ

How do I scrape Bidsquare auction listings?

Run this actor with a maxItems limit, or leave it high for a full sweep. It returns every lot across Bidsquare's live/upcoming calendar and its closed archive, one JSON record per lot.

What data can I get from Bidsquare?

Lot descriptions, categories, pre-sale estimates, bidding activity where the auction house makes it public, closed-lot hammer prices, buyer's premium, dimensions, and photos — plus the auction and auction house each lot belongs to.

Does this cover closed auctions, or just live ones?

Both. Bidsquare Auction Lot Listings Scraper works through the live/upcoming calendar and the closed archive in the same run, so hammer prices from past sales come back alongside current listings.

Do I need a Bidsquare account?

No. The actor needs no login and no API key — point it at a run and it returns lots.

Can I get results from just one auction house or category?

Not as a built-in filter today. Every run covers the full corpus; filter the output dataset by auction_house or category after the fact, or file an issue if a built-in filter would help.

Why Use Bidsquare Auction Lot Listings Scraper?

• Full coverage, not a preview — walks each auction's complete lot catalog instead of the five thumbnails shown on the calendar page
• Closed prices included — hammer prices come back even from auction houses that hide bidding activity behind a login wall on their own site, which is the number appraisers actually need
• One schema, both states — live and closed lots share the same fields, so a comparables file doesn't need two imports
