I'd like to be able to gather information about the apps that a particular user has deployed/registered under their Apple ID. I know that Apple has an iTunes search API available, but I don't see any way to query given an Apple ID (typically represented as an e-mail address). Is there any way to do so? Are there any other search APIs that I've missed that provide this functionality? I know that I can query for an app using the "artistId" parameter, but can't find a way to map the numeric value for the artistId to an Apple ID. Thoughts?
I wouldn't expect Apple to give access to private information. The best you can do (if that helps you at all) is search app store for artist, say Tapbots
http://itunes.apple.com/search?term=tapbots&entity=allArtist
And then use that ID to search all their apps.
