A mini-framework for Django for creating RESTful APIs.
Piston is a relatively small Django application that lets you
create application programming interfaces (API) for your sites.
It has several unique features:
Ties into Django's internal mechanisms.
Supports OAuth out of the box (as well as Basic/Digest or custom auth.)
Doesn't require tying to models, allowing arbitrary resources.
Speaks JSON, YAML, Python Pickle & XML (and HATEOAS.)
Ships with a convenient reusable library in Python
Respects and encourages proper use of HTTP (status codes, …)
Has built in (optional) form validation (via Django), throttling, etc.
Supports streaming, with a small memory footprint.
Stays out of your way.
