retrieval of AppStore charts via API?

Question

i'm looking to query the itunes appstore charts to determine what position a given app holds.

this would need to go as deep as possible with a view to tracking an apps movement from launch to appearing in the top 100 and further.

any ideas?

Answer 1

You can get the top 200 apps, podcasts, etc. from the iTunes RSS feeds:

http://itunes.apple.com/rss

edit: The iTunes RSS feeds now limit you to the top 200. Up until a week ago it would return the top 400

Answer 2

There are plenty of sites out there that do this, but they all operate via some flavor of screen scraping. Apple has no API for this, and I doubt they ever will.
