Last week Google launched a new service called Google AJAX Feed API, an API which is supposed to make it easier to develop “mashup’s” in JavaScript. A “mashup” is a web page or web application that combines the content from one or several sources into one uniform solution.
With Google’s new solution developers are (should be) able to combine feeds through only a few lines of JavaScript. It supports both Atom and RSS feeds.
Google AJAX Feed API can be used free of charge, but does require signing up for a single Google API key.
