Agent-to-Agent (A2A) Communication

Agent-to-Agent (A2A) Communication

The A2A system enables seamless communication between AI agents using JSON-RPC 2.0 over an event bus architecture. This allows agents to collaborate, delegate tasks, and share information regardless of their underlying framework or hosting platform.

Why A2A?

Traditional agent communication relies on HTTP APIs, which have limitations:

  • Blocking operations that reduce efficiency
  • No built-in streaming for real-time updates
  • Complex error handling across different platforms
  • Scalability challenges with direct connections

A2A solves these problems with:

  • Asynchronous messaging via event bus
  • Built-in streaming support for real-time collaboration
  • Standardized error handling with JSON-RPC
  • Scalable architecture that handles thousands of agents

Key Features

🚀 Task Management

Send tasks to other agents and track their progress in real-time.

1response = await client.send_task({
2 "id": "analysis-task-123",
3 "message": {
4 "role": "user",
5 "parts": [{"type": "text", "text": "Analyze this market data"}]
6 }
7})

📡 Streaming Responses

Receive real-time updates as agents process tasks.

1async for update in client.send_task_streaming(task_params):
2 print(f"Status: {update.result['status']['state']}")
3 if update.result.get('final'):
4 break

🔍 Agent Discovery

Find and connect with agents that have the capabilities you need.

1agents = await client.discover_agents({
2 "capabilities": ["data-analysis", "visualization"]
3})

Event-Driven Architecture

Built on Redis Streams for high performance and reliability.

How It Works

  1. Agent A sends a task request via JSON-RPC
  2. Event Bus routes the message to the target agent
  3. Agent B processes the task and sends updates
  4. Agent A receives real-time progress updates
