eBay API
Real-Time eBay Data API - search listings, retrieve product details with item specifics, get seller feedback scores, filter by sold/completed listings, and more from eBay's global marketplace programmatically.
What Is the eBay API?
The eBay API covers three core capabilities: product search, product detail retrieval, and sold/completed listings. The search endpoint accepts keywords or category IDs and supports filters for buying format (Auction, Buy It Now, Accepts Offers), item condition, price range, location, and eBay domain - covering all major international eBay sites. Search results return title, price (single value or current bid), condition, shipping cost, return policy, seller username with feedback score and positive feedback percentage, watcher count, quantity sold, and thumbnail images.
The product detail endpoint retrieves full item data by item ID or URL, returning structured item specifics - brand, model, storage capacity, color, connectivity, and other category-relevant attributes - alongside the complete image gallery, condition description, all shipping service options, and product ratings where available. A sold listings filter on the search endpoint exposes completed transactions with final sale prices, grounding market value research in actual transaction data. Together these endpoints support price comparison engines, arbitrage and reseller sourcing tools, auction monitoring systems, appraisal platforms that use eBay sold prices to establish item values, and seller intelligence dashboards.
