The Search API for Shopping is intended for developers who want to programmatically query data that has been uploaded to Google via the Google Merchant Center. On Google, this data also surfaces on applications like Product Search, Web Search, Book Search, as well as Product Ads.

The Search API for Shopping targets the following use cases:

• Merchants can use the API to query their own data by becoming a Commerce Search user.
• Publishers in the Google Affiliate Network can use the API to access product offers from their advertisers of choice.
