Looking for a mobile apps search API

[alzaeem]

I'm working on an app for Windows 8/ Windows Phone that requires the ability to search existing apps by name in Windows 8/Windows phone stores, as well iOS and Android. The best thing I found so far is mimvi.com, but it's very new and I'm guessing there must be other mature services that solve this problem. Has anyone here had to do something like this before?

Thanks
