Solutions/Comparable Sales API
Comparable Sales API
Find true comparables in one call: verified sold lots matched on artist, category, medium, dimensions, price bracket, and time window, returned with aggregate statistics — count, min/max/average/median, and date range — already computed.
Designed for appraisal workflows, lending collateral reviews, and any product that needs to answer “what do works like this actually sell for?” without building the comps logic yourself.
Example

Dimension-aware
Filter by physical size, the variable that moves art prices most and generic APIs ignore.
Semantic option
Describe the work in plain language and let vector search find visually and materially similar lots.
