is it documented anywhere?

Yes!

I’m happy to dig through code or tests as long as someone can point me in the direction of a definitive list of REST API methods.

All the documentation, including the REST API, is available online at

http://pythonhosted.org/mailman/

This is somewhat out of date though, because it describes 3.0b4, but as I expect to release b5 before the EOY, it will be updated to 3.0b5. In the meantime, you can branch the trunk[*] and view the documentation in-tree. It's also not wonderfully organized - contributions welcome!

Cheers, -Barry
