eBay Shopping API
Call Reference Version 661

A set of Half.com catalog products. This contains stock information about a particular DVD, book, or other product. When you use QueryKeywords in the request, FindHalfProducts returns a maximum of 20 products per page. When you use ProductID in the request, FindHalfProducts usually only returns 1 product. ItemCount is only returned when ProductID is used in the request and the IncludeSelector is set to Items or Details. (If more than one product matches the same ProductID, FindProducts will return all of those products. As of the time of this writing, we expect this to be a rare case.)
