Why learn Flask-RESTX?

Developers should use Flask-RESTX when building REST APIs in Python that require clear documentation and validation, such as in microservices, backend services for web or mobile apps, or internal tools. It is ideal for projects needing automatic API documentation to improve developer experience and client integration, especially in teams where API consistency is critical.
