Unlike Android and other free stuff these APIs are very promising for revenue generation as some of them are very unique to Google itself, and already some are being offered on a Pricing Tier. There are 18 APIs in total with 3 APIs having Pricing while the rest are in beta stages.
I am just listing down all the APIs in one place -
- Google Apps Admin Audit API
With the Google Apps Admin Audit API you can survey the activities of all of your account’s administrators. The API gives details about changes to a key subset of your Google Apps services and features settings including settings for Calendar, Chat, your delegated administrators, Docs, domain configuration, Gmail, Groups, mobile settings, organization hierarchy, Sites, and user settings. In addition to the setting changes, the API returns specifics about the change activity itself, including the IP address used by the administrator.
This API’s functionality is a key building block for your Google Apps account’s IT infrastructure.
.Google Books has a vision to digitize the world’s books. You can use the Google Books API to search content, organize an authenticated user’s personal library and modify it as well.
