AI Agents
Test an A2A agent connection
Validates connectivity and authentication to an A2A agent’s base URL by fetching its agent card, without saving or executing anything. Project-scoped rather than AI-Agent-scoped, since an A2A Agent node can also live in an ordinary Flow with no AI Agent resource behind it.
