android - query the google play store for the version of an app?

Question

is there a way to query the play store for the version of an app without the need for user-credentials. I am aware of this unofficial API:

http://code.google.com/p/android-market-api/

but I don't want to rely on user credentials - I can visit the google play sites in incognito mode via chrome also - so it must be possible somehow. But I found no way and I don't want to fallback on scraping ;-)

Answer 1

Found a suitable API via G+: this is the API: https://androidquery.appspot.com

example call: https://androidquery.appspot.com/api/market?app=org.ligi.fast

and this wrapper/code: https://github.com/androidquery/androidquery
