Attention math nerds everywhere. Everyone’s computational knowledge engine, Wolfram Alpha, has just opened up version 2.0 of their developer API. This version brings many improvements to help you cheat at math and statistics even faster. For instance, API 2.0 supports asynchronous operation, so data that is simpler will be returned immediately, while data that requires more computation will be delivered later. Best of all, it’s now free.
Developers just need to sign up to get an API key to start working with Wolfram Alpha. There is extensive documentation for devs as well. All data is returned in XML by default, but plain text, HTML, or images can be specified. This is a smart way of returning results that should be well-suited to any number of applications. If you build anything great with Wolfram Alpha, make sure to clue us in.
