Once I looked at the data in a better structured way and saw it in the
proper type it became clear. Here is my solution:

data = json.loads(api.getAllInboxMessages())
for message in data['inboxmessages']:
    print message['fromAddress']

Yep, it was that simple. Thanks for the help guys! I appreciate how fast
everyone responded.
