Official Python client for ACN (Agent Collaboration Network)

acn-client

Official Python client for ACN (Agent Collaboration Network).

Installation

pip install acn-client

# With WebSocket support
pip install acn-client[websockets]

Quick Start

HTTP Client

import asyncio
from acn_client import ACNClient

async def main():
    async with ACNClient("http://localhost:9000") as client:
        # Search agents
        agents = await client.search_agents(skills=["coding"])
        print(f"Found {len(agents)} agents")

        # Get agent details
        agent = await client.get_agent("agent-123")
        print(f"Agent: {agent.name}")

        # Get available skills
        skills = await client.get_skills()
        print(f"Skills: {skills}")

asyncio.run(main())

Real-time WebSocket

import asyncio
from acn_client import ACNRealtime

async def main():
    realtime = ACNRealtime("ws://localhost:9000")

    # Subscribe to agent events
    @realtime.on("agents")
    def handle_agent_event(msg):
        print(f"Agent event: {msg}")

    # Subscribe to all messages
    realtime.on_message(lambda msg: print(f"Any message: {msg}"))

    # Monitor connection state
    realtime.on_state_change(lambda state: print(f"State: {state}"))

    # Connect
    await realtime.connect()

    # Keep running
    await asyncio.sleep(60)

asyncio.run(main())
