Google Data API's

Get google search results for all data streems

Here is an example of getting their images:

http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=Paris%20Hilton&callback=foo&context=bar

These API’s can be called through JavaScript scripts and class definitions Google provides (see below) or trough URL API  calls.

These API’s are great for mashup sites or to help you increase the on page data you display to your users to show relevant topics and increase engagement or decrease clicks for data as the browse your site. I used a couple of them, for example, on http://www.appmakr.com/try_demo to pull relevant RSS feeds and Images based on a companies domain name.
