Extract statistics from google play

I'm building some statistics and would like to have the statistics from google play (the app store) as well. Information like most popular, downloads, price, etc.

Does anyone know if there is an API for this or do I have to scrape it myself?

How do I check my Google Play stats?

Open Play Console and go to the Statistics page. To view your app's absolute performance, remain in the App statistics tab (the default tab). To view normalized metrics and benchmarks, select the Compare to Peers tab. At the top-right of your screen, select the date range you want to view.

There's a project called android-market-api http://code.google.com/p/android-market-api. Start from there.

http://code.google.com/p/android-market-api/source/browse/trunk/AndroidMarketApi/proto/market.proto. Look at App definition there to get idea of what you could extract.

You can ask the guy who wrote it how he reverse-engineered the protocol of Android market.

Using it you can make searches and then get info per application.
