Liveauctioneers Art Prices Realized Scraper

Scrape prices-realized data from LiveAuctioneers for sold art lots. Returns hammer price, estimates, artist, medium, auction house, and full lot details.

What it does

The actor queries LiveAuctioneers' internal JSON APIs — no HTML parsing. It uses a Firefox TLS fingerprint (impit) to bypass the site's TLS fingerprint gate and calls three API endpoints:

• search-party — paginated sold-lot search by keyword, category, and/or auction house
• item-facets — artist name, medium, and art category enrichment per lot
• content/items — lot detail by itemId (for BYO URL mode)
• priceresultsummary — slug→itemId resolution for legacy URL formats

Modes

1. Keyword / category search (default)

Set keyword and/or categoryId to page through sold lot results. Combine with auctionHouseId to scope to a single auction house.

2. BYO lot URLs

Supply a list of price-result URLs (e.g. https://www.liveauctioneers.com/price-result/some-lot-slug/). The actor resolves each URL to a lot ID and fetches full detail and enrichment data.

Input

Field	Type	Description
keyword	string	Search keyword or artist name (e.g. "Picasso", "watercolor landscape")
categoryId	integer	LiveAuctioneers category ID (1=Art, 8=Drawings, 14=Paintings, 12=Prints & Multiples)
auctionHouseId	integer	Filter to a specific auction house by their seller ID
lotUrls	array	List of price-result URLs for direct lot lookup
maxItems	integer	Maximum number of records to return (default: 10)

Use cases

• Art market research and price benchmarking
• Artist valuation and market trend analysis
• Auction house performance tracking
• Collection appraisal support
• Investment research for art assets

Notes

• Results are limited to sold lots with realized prices
• Artist enrichment (artist_name, medium, category) comes from LiveAuctioneers' facets API and may not be available for all lots
• Dimension extraction uses pattern matching on the description field; not all lots include dimensions
• The BYO URL mode supports both modern slugs (<itemId>-<catalogId>-title) and legacy title-only slugs
