The Browse API lets shoppers search eBay listings by keyword, category, GTIN, product, charity, compatibility criteria, or image, and refine results with filters such as aspects, compatibility, field values, and UI parameters through the item_summary resource.

The item resource lets applications retrieve detailed information for a specific item or all items in an item group, and check whether a product is compatible with a specified item, such as whether a specific vehicle is compatible with a specific part. The item resource also supports legacy item identifiers alongside RESTful item IDs, which use different formats. This helps developers work with stored or historical legacy item IDs when using the Browse API.

All methods in the Browse API require an Application access token, which is obtained using the client credentials grant flow.
