Short answer: You can list render services in Render by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Render List Render Services action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

[{"service": {"id": "srv-abc123","name": "my-web-app","type": "web_service","serviceDetails": {"url": "https://my-web-app.onrender.com"}}}]
Use these fields in downstream nodes for routing, logging, or error handling.
Any of these apps can fire this action as part of a workflow.
