This is the simple way to create a web endpoint on Modal. The function behaves as a FastAPI handler and should return a response object to the caller.

Endpoints created with @app.web_endpoint are meant to be simple, single request handlers and automatically have CORS enabled. For more flexibility, use @app.asgi_app.
