How to access a contributed module Information from drupal.org Is there any API to access Information about a contributed module
from drupal.org site? 
How does Update Manager access information
from drupal.org?


By finding this I think I too could access other data similarly and I also need Hook API documents to be accessed from drupal.org in my site. 

Did anyone do this before? If so please guide me.
An update URL is formatted as:

http://updates.drupal.org/release-history/[project-name]/[api-version]


So for Views v7, for example, that would be:

http://updates.drupal.org/release-history/views/7.x


I think that's as much information as Drupal.org makes available about modules via its API. You won't find a structured way to query information about hooks, for the same reasons we talked about in your similar recent question
