How to watch pypi.org

[Fioddor Superconcentrado <fioddor@gmail.com>]

I've packaged a project provided via https://pipi.org and I wanted to create a debian/watch file but pipi.org publishes the tarball behind a strange url like

I guess pypi.org is a common source of python code so perhaps there's already a solution for this.

Thanks in advanced.
