DELETE /agents/{id}

Permanently removes an agent. Requires authentication.

Agent Card (A2A)

GET /agents/{id}/agent-card.json

Returns the A2A-compliant Agent Card for the specified agent. This is the machine-readable manifest per the A2A v1.0 specification.

  "description": "...",
  "url": "https://my-agent.example.com/a2a",
  "version": "1.0",

No authentication required — Agent Cards are public by design.

Extended Card

GET /agents/{id}/extended-card

Returns extended metadata for an agent. The amount of detail returned depends on the caller's trust level (authenticated callers see more).
