"""08 -- drive a running gradio app programmatically with gradio_client.

Every gradio app is also an HTTP API, which makes it scriptable from CI.
Start a template in one shell, then run this in another:

    python 01_hello_interface.py
    python 08_api_client.py http://127.0.0.1:7860/

gradio_client fetches the app's schema from the server itself, so nothing
beyond the app's own host and port is needed.

Endpoint names are NOT stable across gradio majors: gradio 4 names the single
gr.Interface function "/predict", while gradio 5+ derives the name from the
function instead ("/greet" for 01_hello_interface.py). Rather than hardcode
either, discover the endpoint from the schema.
