Ability to customise API endpoints?

[andrespch]

I want to make it possible to send messages to my agent deployed on Cloud Run without having to create a session every time. I'm wondering if there is a way to define additional logic before deploying via adk deploy where I can create a clear sessions for each incoming request.

I am also considering deploying a separate FastAPI app that will wrap the session creation and the run_sse I'm curious if there is a more convenient/performant way to do this?

Thank you!
