Use the api_name when calling an app like a function

[freddyaboulton]

• I have searched to see if a similar issue already exists.

Properly using a space like an api requires knowing the fn_index. If you're a downstream consumer of an app, you may not know the fn_index and the fn_index can change if the upstream app is refactored.

Describe the solution you'd like
Would be nice to be able to do something like

demo = gr.Blocks.load("path-to-demo")
output = demo(input, api_name="prediction-route")

Where "prediction-route" is the api_name given to the event in the upstream space.

isn't this already supported via events? It is down to the app author to expose that on a per event basis rather than the consumer. When loading, the 'loader' shouldn't be impacting this, unless I'm misunderstanding this issue.

If you're hitting the api via curl or something, you can use api_name in the route.

But if you load the space into python, you have to pass in the fn_index, not the api_name.
