Bonanza is an online marketplace with integrated social features that allow members of the community to engage other buyers and sellers. The site offers newsletters, seller profiles and real time chat for buyers and sellers of collectibles, antiques, clothing, jewelry, books, and other items.
Developers can interface their own applications directly with the Bonanza marketplace using the Bonanza Bonapitit REST API. The API accepts input in either JSON or XML format and output is delivered in JSON. Functionality includes search and lookup, account management, item editing, and notifications.
