 "title": "Call A2A agents through the AI Gateway",
 "page_title": "How to call A2A agents through the AI Gateway with Litellm",
 "summary": "Register an A2A agent on the gateway and send it messages from any A2A client.",
 "who": "A developer or platform team that runs agents from frameworks such as LangGraph or Pydantic AI and wants one gateway entry point for them.",
 "problem": "Each agent framework exposes its own endpoint and auth, so clients need separate setup for every agent.",
 "outcome": "A client sends a message to a named agent through the gateway and prints the text reply.",
 "steps": [
  "Add your agent to the AI Gateway by following https://docs.litellm.ai/docs/a2a#adding-your-agent and set protocolVersion to 1.0 or 0.3",
  "Install the A2A client with `pip install a2a-sdk>=1.1.0` (inferred from the README requirement) (inferred, check the README)",
  "Set the Authorization header to a LiteLLM master key or virtual key",
  "Create the client from the agent card at http://localhost:4000/a2a/<agent-name> and call send_message"
 ],
 "agent_prompt": "Using the litellm repo at <path>, register the agent <agent_name> on the gateway and send it the message 'Hello!' through an A2A client pointed at http://localhost:4000/a2a/<agent_name>. Expected output: the agent's text reply printed to the console. Verify that the agent card loads before sending the message.",
 "agents": [
  "any"
 ],
 "difficulty": "Advanced",
 "time": "60 minutes",
 "basis": "readme",
 "caveat": "The README requires a2a-sdk version 1.1.0 or newer, and the agent must already be running on its own framework before the gateway can call it.",
 "category": "Software and DevOps",
 "tags": [

 ],
 "lang": "python",
 "requirements": [
  "Python and the uv package manager installed",
  "API keys for the LLM providers you plan to call, such as OpenAI or Anthropic",
  "For the gateway use cases: a machine to run the proxy server on and a LiteLLM master key or virtual key for clients"
