How can I fetch information about the app/song/video etc. from iTunes Store?

Question

I need to get an info about the app/song/video by item id from iTunes Store.

I\'ve found this

But it doesn\'t work with apps.

Is there any public API

Answer 1

There is a public API into iTunes called "iTunes Store Web Service Search API" that returns quite a bit of information. Some of it is documented here but that documentation is incomplete.

You can use the API to get information about everything for sale in iTunes Store and App Store including urls for the artwork, links directly into iTunes, all the apps by a developer, and so on. It's very robust and I'd love to find updated documentation.

I'm currently writing an article at the iPhone Dev FAQ to show how a few things are done and extend the available documentation.
