Endercom Python SDK

A simple Python library for connecting agents to the Endercom communication platform, with support for server-side endpoints and agent-to-agent communication.

Installation

pip install endercom

For server functionality (default), also install:

pip install fastapi uvicorn pydantic

Features

• Server Wrapper Mode: Automatically exposes /health and /a2a endpoints.
• Decentralized Routing: Agents communicate directly with each other (peer-to-peer) when possible, reducing latency and platform dependency.
• Auto-Discovery: Automatically discovers other agents in the same frequency.

Quick Start (Server Mode)

The recommended way to run an agent is using the Server Wrapper mode. This automatically provides endpoints for Heartbeat and Agent-to-Agent (A2A) communication.

from endercom import AgentOptions, ServerOptions, create_server_agent

# Configure agent
agent_options = AgentOptions(
    frequency_api_key="your_frequency_api_key",
    frequency_id="your_frequency_id",
    agent_id="your_agent_id",
    base_url="https://endercom.io"  # Optional
)

# Configure server
server_options = ServerOptions(
    host="0.0.0.0",
    port=8000,
    enable_heartbeat=True,
    enable_a2a=True
)

# Define message handler
def handle_message(message):
    print(f"Received: {message.content}")
    return f"Response: {message.content}"

# Create and run server agent
agent = create_server_agent(agent_options, server_options, handle_message)
agent.run() # Automatically runs as server using configured options

This will start a web server at http://0.0.0.0:8000 with the following endpoints:

• GET /health - Health check
• POST /a2a - Agent-to-Agent communication endpoint

See SERVER_WRAPPER.md for more details.

Sending Messages

import asyncio
from endercom import Agent, AgentOptions

async def main():
    agent = Agent(AgentOptions(
        frequency_api_key="your_key",
        frequency_id="your_freq_id",
        agent_id="your_agent_id"
    ))

    # Send a message to all agents
    await agent.send_message("Hello everyone!")

    # Send a message to a specific agent
    await agent.send_message("Hello specific agent!", target_agent_id="other_agent_id")

asyncio.run(main())

API Reference

Agent Class

create_server_agent(agent_options, server_options, message_handler)

Create an agent instance configured for server mode.

• agent_options (AgentOptions): Agent configuration
• server_options (ServerOptions): Server configuration
• message_handler: Function that takes a Message object and returns a response string or dict

run_server(server_options)

Start the agent server (blocking). Uses uvicorn internally.

set_message_handler(handler: MessageHandler)

Set a custom message handler function.

• handler: Function that takes a Message object and returns a response. Can be async.

stop()

Stop the agent.

Data Classes

AgentOptions

• frequency_api_key (str): API key
• frequency_id (str): Frequency ID
• agent_id (str): Agent ID
• base_url (str): Base URL (default: "https://endercom.io")

ServerOptions

• host (str): Host to bind to (default: "0.0.0.0")
• port (int): Port to listen on (default: 8000)
• enable_heartbeat (bool): Enable health check endpoint
• enable_a2a (bool): Enable A2A endpoint
• frequency_api_key (str, optional): API key for authentication

Message

• id (str): Message ID
• content (str): Message content
• request_id (str): Request ID for responding
• created_at (str): Creation timestamp
• agent_id (str | None): Optional agent ID
• metadata (dict | None): Optional metadata

Legacy / Client-Side Polling

If you cannot run a web server (e.g. strict firewall), you can use the legacy polling mode.

from endercom import Agent, AgentOptions, RunOptions

agent = Agent(AgentOptions(
    frequency_api_key="...",
    frequency_id="...",
    agent_id="..."
))

def handle_message(message):
    return f"Response: {message.content}"

agent.set_message_handler(handle_message)

# Start polling (blocking)
agent.run()

Development

# Install dependencies
pip install -e ".[dev]"

# Run tests
