WolframAlpha releases API

Wolfram|Alpha is an interesting query answering system developed by Wolfram Research that is a blend of a question answering system and a Semantic Web alternative. It tries to interpret and answer queries expressed as a sequence of words from a large collection of interlinked tables. Oh, and Mathematica is in thrown in for free. A free Web version was released last Spring.

The news today is that Wolfram|Alpha has released an API, as noted in their blog:

“The API allows your application to interact with Wolfram|Alpha much like you do on the web—you send a web request with the same query string you would type into Wolfram|Alpha’s query box and you get back the same computed results. It’s just that both are in a form your application can understand. There are plenty of ways to tweak and control the results, as well.”

The pricing plan runs from $60/month for 1000 (6 cents a query) queries to $220K for up to 10M queries/month (2.2 cents a query). programming language bindings are available for Java, PHP, Perl, Python, Ruby and .NET.

Their original web interface remains free, but the TOS specifies that it “may be used only by a human being using a conventional web browser to manually enter queries one at a time.”
