Price It By Phone, and the Twilio API

I won the Twilio+AppEngine contest with Price It By Phone, an app that lets you look up Amazon.com book prices by touch-tone phone.  Right now it's up and running at http://price-it.appspot.com.

Price It By Phone, and the Twilio API

If you try it and run into problems, please let me know!

My interview with Twilio is here

I like the Twilio API a lot.  It's the easiest-to-use API imaginable.  You set up your Twilio phone number with a URL to post to.  Then, when you call the phone number, Twilio sends a POST request to that URL with the caller phone # and the digits entered as parameters. 

They have a Twilio-AppEngine sample among their demo apps.  This is awesome.  As you can see, I'm back to really liking GAE again, a lot.

I'm putting a bit more time into Price-It and hoping to launch v2 soon.  Features that I want to put into it for sure:  support for ISBNs with Xs and any other chars that appear in them, user accounts, verifying your phone # before you're allowed to see your book lookup history, being able to delete your history.  Possible features to be added: integration with Amazon wish list, FB connect. 

Also, I want to make it look web2.0 shiny, with cute illustrations and bright, designed gradients.  Yes, I know that the dark, trippy background doesn't have mass appeal.  Sometimes I make art for the sake of making myself happy :)  View the page's source code to see how it's done.

If you have other feature ideas, I'd be interested in hearing them.

Congratulations on winning the contest! A great app!

I'm really curious how you developed and debugged the Twilio pieces using the GAE SDK. Were you just forced to deploy continuously and test on the live appspot site? Or is there some way to stub out the Twilio calls to simulate them on localhost?

Thanks!
