Get Agent Card

Changed on

Get the agent card for an agent (A2A discovery endpoint).

Supports both standard paths:

  • /.well-known/agent-card.json
  • /.well-known/agent.json

The URL in the agent card is rewritten to point to the LiteLLM proxy, so all subsequent A2A calls go through LiteLLM for logging and cost tracking.

get/a2a/{agent_id}/.well-known/agent-card.json
