About SoldComps

SoldComps is an API for pulling eBay sold-listing data. A single GET request with a keyword returns completed sold items rather than asking prices, and each item carries the price it sold for, shipping cost, currency, end date, condition, seller feedback score and a link to the listing. The response is plain JSON, with no OAuth, XML or pagination tokens to deal with.

Searches can cover eight eBay country sites, including the US, UK, Germany, France, Italy, Spain, Canada and Australia, and be narrowed by category, price, condition and date window, with a history window of up to 90 days for each search. A request counts as one search whether it returns ten results or 240. The homepage also offers a live demo, a usage dashboard and per-account API keys, and positions the service for resellers checking resale value before buying stock and for developers adding market pricing to their own apps.
