Python scripts to register a OAuth1 client with pump.io, to list your status updates and to post an note. Heavily inspired PyPump; Kudos to https://github.com/xray7224/PyPump. To use it run register.py first.

userurl = config["baseurl"]+'/api/user/%s/feed' % config["username"]

client = OAuth1(

This was created 7 years ago - I had no idea pump.io was still a thing, and I wouldn't have expected that this still works.
Thanks for the notes!
