Great looking site, and good luck. My IP data was pretty much bang on, something I haven't seen before.
However, I was just looking at your Python SDK: https://github.com/ipdata/python/blob/master/ipdata/ipdata.p...
What are you thinking. Never do this in a library. Also it looks a bit amaterish, as it's your only currently supported library I'd fix it up a bit - don't add .pyc/dist files to git, make it pep8, remove sys.exit() in a library (!!!) etc.
