Congratulations to Audrey Roy -- her "Price It By Phone" application won the Google App Engine + Twilio developer contest that ran from September 21st to October 4th. Audrey will receive $1000 in Google App Engine credit, and a Dell Netbook from Twilio.

Audrey hacked together her contest submission in under 48 hours after going to an art museum and discovering that the $60 box she wanted was only $37 on She used the Amazon Product Advertising API to look up the best used and new prices for books by ISBN number, using any touch tone phone.

Look up book prices by calling (877) 265-8137. Enter the book's 10-digit ISBN number after the prompt. The voice will tell you's lowest new and used prices for the book. Then, to see the list of books that you've already price-checked, with links to their Amazon detail pages, enter your phone number at
