Agent Discovery

Get the agent card

Changed on Apr 21, 2026

The A2A standard discovery document. Any client that knows the agent's base URL can GET this to learn the agent's DID, capabilities, published skills, and where to send requests.

OPTIONS and HEAD are also accepted — useful for CORS preflight and liveness probes respectively.
