# Get an agent's public A2A Agent Card

> Return the public A2A (Agent-to-Agent) Agent Card for an agent at the spec-canonical /.well-known/agent-card.json path. The card advertises the agent's name, description, skills, accepted input/output modes, and HMAC authentication requirement so federation peers can discover it and delegate tasks. Unauthenticated — the tenant schema is supplied via the required 'tenant' query parameter, and the endpoint returns 404 unless the agent's discovery mode is public.
