HI Guys, In case its of help to anyone, my company is open sourcing the framework we built using Twisted Web to help us build & serve JSON REST APIs: https://github.com/williamsjj/shiji We've been using it successfully for a few years and built it to solve a bunch of repetitive tasks for us: * API versioning * Signed cookie handling w/ support for key rotation. * Enforcement of required JSON arguments and validation of JSON argument datatypes. * Enforcement of required query string arguments. * Standardized JSON error responses. * Basic sanity checking of pagination arguments for API calls that support it. * Automatic generation of API documentation based on call docstrings and subclasses of our APIError super class. MIT License, so feel free to do with it as you please. If you have any questions, just let me know. Hope it's useful to someone else as well. -J
