RedCircle API allows you to retrieve Target Product Data by GTIN, ISBN or UPC code when making a type=product or type=reviews request. There is no additional charge for this service.

To lookup Target Product Data by GTIN, ISBN or UPC code you simply use the gtin parameter instead of the tcin when making a type=product request.

When the gtin parameter is supplied RedCircle will attempt to look up the GTIN/ISBN/UPC on Target before then retrieving product details for the resultant tcin .
