conversimple-sdk 0.1.0

Python SDK for Conversimple Conversational AI Platform

Conversimple SDK

Python client library for the Conversimple Conversational AI Platform.

This SDK enables customers to build and deploy AI agents that integrate with the Conversimple platform's WebRTC infrastructure and conversation management, providing real-time voice conversation capabilities with function calling support.

Features

• Real-time Voice Conversations: Integrate with WebRTC-based voice conversations
• Function Calling: Define tools that can be executed during conversations
• Event-Driven Architecture: React to conversation lifecycle events
• Auto-Reconnection: Fault-tolerant WebSocket connection with exponential backoff
• Type Hints: Full typing support for better development experience
• Async/Await Support: Both sync and async tool definitions

Quick Start

Installation

pip install conversimple-sdk

Basic Usage

import asyncio
from conversimple import ConversimpleAgent, tool

class MyAgent(ConversimpleAgent):
    @tool("Get current weather for a location")
    def get_weather(self, location: str) -> dict:
        return {"location": location, "temperature": 72, "condition": "sunny"}

    def on_conversation_started(self, conversation_id: str):
        print(f"Conversation started: {conversation_id}")

async def main():
    agent = MyAgent(
        api_key="your-api-key",
        customer_id="your-customer-id"
    )
    
    await agent.start()
    
    # Keep running
    while True:
        await asyncio.sleep(1)

if __name__ == "__main__":
    asyncio.run(main())

Core Concepts

Agent Session Model

Each ConversimpleAgent instance handles a single conversation session. For multiple concurrent conversations, create multiple agent instances:

# Per-conversation agent instances
async def handle_conversation(conversation_id):
    agent = MyAgent(api_key=api_key, customer_id=customer_id)
    await agent.start(conversation_id=conversation_id)

Tool Registration

Define tools using the @tool and @tool_async decorators:

from conversimple import tool, tool_async

class BusinessAgent(ConversimpleAgent):
    @tool("Look up customer information")
    def lookup_customer(self, customer_id: str) -> dict:
        # Synchronous tool execution
        return customer_database.get(customer_id)
    
    @tool_async("Send email notification")
    async def send_email(self, email: str, subject: str, body: str) -> dict:
        # Asynchronous tool execution
        result = await email_service.send(email, subject, body)
        return {"sent": True, "message_id": result.id}

Event Callbacks

Handle conversation lifecycle events:

class MyAgent(ConversimpleAgent):
    def on_conversation_started(self, conversation_id: str):
        print(f"🎤 Conversation started: {conversation_id}")
    
    def on_conversation_ended(self, conversation_id: str):
        print(f"📞 Conversation ended: {conversation_id}")
    
    def on_tool_called(self, tool_call):
        print(f"🔧 Executing tool: {tool_call.tool_name}")
    
    def on_error(self, error_type: str, message: str, details: dict):
        print(f"❌ Error ({error_type}): {message}")

Configuration

Environment Variables

export CONVERSIMPLE_API_KEY="your-api-key"
export CONVERSIMPLE_CUSTOMER_ID="your-customer-id" 
export CONVERSIMPLE_PLATFORM_URL="ws://localhost:4000/sdk/websocket"
export CONVERSIMPLE_LOG_LEVEL="INFO"

Programmatic Configuration

agent = ConversimpleAgent(
    api_key="your-api-key",
    customer_id="your-customer-id",
    platform_url="wss://platform.conversimple.com/sdk/websocket"
)

Examples

The SDK includes several example implementations:

Simple Weather Agent

python examples/simple_agent.py

A basic agent that provides weather information, demonstrating:

• Tool registration with @tool decorator
• Conversation lifecycle callbacks
• Basic agent structure

Customer Service Agent

python examples/customer_service.py

Advanced customer service agent with multiple tools:

• Customer lookup and account management
• Support ticket creation
• Email notifications
• Refund processing
• Async tool execution

Multi-Step Booking Agent

python examples/booking_agent.py

Complex booking workflow demonstrating:

• Multi-turn conversation state management
• Booking creation, confirmation, and cancellation
• Business rule validation
• Transaction-like processes

API Reference

ConversimpleAgent

Main agent class for platform integration.

Methods

• __init__(api_key, customer_id=None, platform_url="ws://localhost:4000/sdk/websocket")
• async start(conversation_id=None) - Start agent and connect to platform
• async stop() - Stop agent and disconnect
• on_conversation_started(conversation_id) - Conversation started callback
• on_conversation_ended(conversation_id) - Conversation ended callback
• on_tool_called(tool_call) - Tool execution callback
• on_tool_completed(call_id, result) - Tool completion callback
• on_error(error_type, message, details) - Error handling callback

Tool Decorators

@tool(description)

Register synchronous tool function.

@tool("Description of what this tool does")
def my_tool(self, param1: str, param2: int = 10) -> dict:
    return {"result": "success"}

@tool_async(description)

Register asynchronous tool function.

@tool_async("Description of async tool")
async def my_async_tool(self, param: str) -> dict:
    await asyncio.sleep(0.1)  # Async operation
    return {"result": "success"}

Type Hints

The SDK automatically generates JSON schemas from Python type hints:

• str → "type": "string"
• int → "type": "integer"
• float → "type": "number"
• bool → "type": "boolean"
• list → "type": "array"
• dict → "type": "object"
• Optional[T] → Same as T (nullable)

Protocol Details

WebSocket Messages

The SDK communicates with the platform using these message types:

Outgoing (SDK → Platform)

• register_conversation_tools - Register available tools
• tool_call_response - Tool execution results
• tool_call_error - Tool execution failures
• heartbeat - Connection keepalive

Incoming (Platform → SDK)

• tool_call_request - Tool execution requests
• conversation_lifecycle - Conversation started/ended
• config_update - Configuration updates
• analytics_update - Usage analytics

Message Format

Tool registration:

{
  "conversation_id": "conv_123",
  "tools": [
    {
      "name": "get_weather",
      "description": "Get weather for location", 
      "parameters": {
        "type": "object",
        "properties": {
          "location": {"type": "string"}
        },
        "required": ["location"]
      }
    }
  ]
}

Tool execution:

{
  "call_id": "call_abc123",
  "result": {"temperature": 22, "condition": "sunny"}
}

Error Handling

The SDK provides comprehensive error handling:

Connection Errors

• Automatic reconnection with exponential backoff
• Configurable retry attempts and timeouts
• Connection state monitoring

Tool Execution Errors

• Automatic error reporting to platform
• Exception wrapping and formatting
• Timeout handling

Logging

import logging

# Configure SDK logging
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger("conversimple")
