Wolfram Alpha To Open Up With an API [guardian.co.uk]

At the moment, Alpha generates results that you can see on the website, export as a PDF or "play" using a Mathematica plug-in. Soon, Wolfram will be opening up its curated data that can be queried using an API, Conrad Wolfram said. This will provide yet another source of data that you can use to create projects and mash-ups with the information that we provide at the Data Store.
