For Gnocchi we've been relying on voluptuous¹ for data validation, and
Pecan as the rest of the framework – like what's used in Ceilometer and
consors.

I find it a pretty good option, more Pythonic than JSON Schema – which
has its pros and cons too.

What I'm not happy with is actually Pecan, as I find the routing system
way too much complex in the end. I think I'd prefer to go with something
like Flask finally.

This is going to happen in a few cycles I hope for Ceilometer.
