Agent Card

A2A Protocol v0.3 compatible agent card for automated discovery by other agents.

What is A2A?

The Agent-to-Agent Protocol (A2A) is an open standard for service discovery between autonomous agents. It allows agents to find and understand other agents' capabilities without human configuration—just fetch /.well-known/agent.json.

Endpoint

GET /.well-known/agent.json

Returns a standardized agent card following the A2A Protocol specification. Other agents can use this to discover available skills and capabilities.
