Extract sold lot data from Bonhams auction results. For each sold lot the actor captures the artist name, artwork title, medium, dimensions, creation year, pre-sale estimate range, hammer price, and sale metadata. Ideal for art-market appraisers, dealers, insurers, and researchers who need Bonhams price-realized data at scale.
What does this actor scrape?
The actor crawls Bonhams.com across three levels:
- Auction results listing — discovers past sales from
/auctions/results/ - Individual sale pages — enumerates all lots within a sale
- Lot detail pages — extracts full data for each sold lot
You can also provide direct URLs to specific lot pages or sale pages and the actor will extract data starting from that level.
Features
- Scrapes complete lot records including estimate range, hammer price, and currency
- Handles GBP, USD, and EUR hammer prices automatically
- Extracts medium and dimensions from catalogue descriptions
- Follows Next.js SSR pages — no JavaScript rendering required
- Residential proxy routing for reliable access
- Supports
maxItemscap for targeted extraction
