 ### Open Source projects
 

[The Open Platform](http://open-platform.theguardian.com/) is a public web service for accessing all the content the Guardian creates, categorized by tags and section.

The Developer key (for any non-commercial usage of the content, such as student dissertations, hackathons, nonprofit app developers) has the following features:

* Up to 12 calls per second
* Up to 5,000 calls per day
* Access to article text
* Access to over 1,900,000 pieces of content
* Free for non-commercial usage

Even though they do have a commercial version, the free Developer version seems quite helpful and enough for most developer needs.
