Guys! Thanks a lot for all your responses and willingness to help! Yesterday I noticed this `requires_dist` in response for Requests package. But actually it was the only one that had this field populated from many packages that I asked API for. So this cannot be reliable way of getting dependecies.
So if not using pip, the only way to get dependencies is from built packages: .whl and .egg. So in .egg it'd be: *EGG_INFO/requires.txt* and in .whl : *<packageName-version>.dist-info/metadata.json*, right? Thanks a lot!
