## AI overview

A technical discussion of composable architecture in a Flask-Restful REST API, focusing on reqparse validation and the use of reusable validator functions to keep special-case handling out of general-purpose parsing code.

## Source excerpt

I am the primary maintainer of a significant REST API written using Flask-Restful. Flask-Restful is a pretty full-featured library for creating REST frameworks with Flask. It features everything you need to manage routing to class-based resources, a library for marshalling objects to JSON format, and reqparse, an argparse-inspired library for writing input parsers.
