Unfortunately, due to copyright issues we cannot let people use our API to display artworks anywhere outside of the Artsy site. We're working on it. Please email firstname.lastname@example.org if you would like to be notified when we launch our API program.
The Artsy API uses many of the same standards as other APIs you may be familiar with. All requests are simple GET, POST, PUT or DELETE requests that return JSON or JSONP. The Artsy API can be accessed with XApp or OAuth 2.0.
