Wolfram Alpha API v2: Radically new pricing including free "experimental" access

They don't seem to provide any pricing information beyond the free, non-commercial level. This seems unfortunate, and signals to me that if I'm not making a "major" product, I probably wouldn't be able to afford it.

I was able to receive an upgrade for

https://chrome.google.com/extensions/detail/papfpipabpficccg...

That included upgraded API thresholds and all, and I wouldn't consider the Chrome extension to be a "major product"

Glad to see they learned from their previous pricing, http://products.wolframalpha.com/api/pricing.html, where the cheapest tier was 1000 requests for $60. Dunno why it took them so long given the angry backlash to their original API, http://blog.wolframalpha.com/2009/10/15/the-wolframalpha-api...

I just signed up for the free API. It took a few minutes getting the Ruby client library working but it seems pretty cool. The 2000 free API calls per month is not as generous as, for example, the Open Calais web service's 50K free calls per day. That said I really appreciate the free use to kick the tires.
