We've added a new API section where we will store all documentation and how-to guides for our APIs. The new forum can be found under
Web Tools and is called
Xavier APIs.
The first API we've created is a currency exchange rate API where you can get historical exchange rates for 38 currencies since 4th of January 1999. You can also using the API create nice looking flash graphs that will be updated daily with new fresh data

To see an example graph you can have a look at this one showing the exchange rate between USD and EUR for the last 3 months:
