You can use this link to fetch all of them:

http://connect20.magentocommerce.com/community/packages.xml

However, it still won't be too reliable as it contains also extensions which are no longer available on Magento Connect site.

You can also fetch list of releases for single extension eg:

http://connect20.magentocommerce.com/community/m2epro_ebay_magento/releases.xml

And then extension release details:

http://connect20.magentocommerce.com/community/m2epro_ebay_magento/3.0.0/package.xml

There are some descriptions and other data there, however it doesn't include url or image.

FYI, all this details come from Mage_Connect_Rest class which exist in each Magento release.
