Django open inviter is a python port of the PHP api client for openinviter.com’s contact importer to work with Django. I build it for our fashion community, Fashiolista.com, where it is currently in production usage and fully functional. If you are a member of Fashiolista (which I highly doubt given the different audiences) you can test it by clicking find friends in your profile.
Usage is extremly straight forward:
from django_open_inviter.open_inviter import OpenInviter o = OpenInviter() contacts = o.contacts('email@example.com', 'test')
