Basic Installation

pip install ai-mesh-sdk

With Optional Dependencies

# With LangChain integration
pip install ai-mesh-sdk[langchain]

# For development
pip install ai-mesh-sdk[dev]

# All optional dependencies
pip install ai-mesh-sdk[langchain,dev]

Quick Start

Synchronous Client

import os
from mesh_sdk import MeshClient

# Initialize the client
client = MeshClient(api_key=os.getenv("MESH_API_KEY"))

# List available agents
agents = client.list_agents()
print(f"Found {len(agents)} agents")

# Call an agent
response = client.call_agent(
    agent_id="your-agent-id", 
    inputs={"query": "What is the weather today?"}
)
print(response.data)

# Chat completions (OpenAI-compatible)
messages = [{"role": "user", "content": "Hello!"}]
response = client.chat_completions(
    model="gpt-3.5-turbo",
    messages=messages,
    temperature=0.7
)
print(response.choices[0].message.content)

Asynchronous Client

import asyncio
from mesh_sdk import AsyncMeshClient

async def main():
    # Initialize async client
    async with AsyncMeshClient(api_key=os.getenv("MESH_API_KEY")) as client:
        
        # List agents asynchronously
        agents = await client.list_agents()
        print(f"Found {len(agents)} agents")
        
        # Call agent asynchronously  
        response = await client.call_agent(
            agent_id="your-agent-id",
            inputs={"query": "Analyze this data"}
        )
        print(response.data)
        
        # Async chat completions
        messages = [{"role": "user", "content": "Hello!"}]
        response = await client.chat_completions(
            model="gpt-4",
            messages=messages
        )
        print(response.choices[0].message.content)

# Run the async function
asyncio.run(main())

Streaming Responses

# Streaming chat completions
messages = [{"role": "user", "content": "Tell me a story"}]

for chunk in client.chat_completions(
    model="gpt-3.5-turbo",
    messages=messages,
    stream=True
):
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

Agent Types

The Mesh platform supports three types of agents:

1. LLMs (Large Language Models)

Direct access to language models via OpenAI-compatible chat completions:

# List available LLMs
llms = client.list_llms()

# Use with chat completions
response = client.chat_completions(
    model="gpt-4",
    messages=[{"role": "user", "content": "Hello!"}]
)

2. Tools

Specialized functions that perform specific tasks:

# List available tools
tools = client.list_tools()

# Call a tool
response = client.call_agent(
    agent_id="search-tool-123",
    inputs={"query": "Python programming", "max_results": 10}
)

3. Autonomous Agents

Complex workflows that can use multiple tools and make decisions:

# List workflow agents
workflows = client.list_workflow_agents()

# Execute a workflow
response = client.call_agent(
    agent_id="data-analysis-workflow-456", 
    inputs={"dataset_url": "https://example.com/data.csv"}
)

LangChain Integration

Mesh SDK provides seamless integration with LangChain:

from mesh_sdk import MeshClient
from mesh_sdk.integrations.langchain import to_langchain_tools

# Initialize client
client = MeshClient(api_key="your-api-key")

# Convert Mesh agents to LangChain tools
tools = to_langchain_tools(client)

# Use with LangChain agents
from langchain.agents import create_react_agent, AgentExecutor
from langchain import hub

# Get a prompt template
prompt = hub.pull("hwchase17/react")

# Create LangChain agent (you'll need a separate LLM)
agent = create_react_agent(your_llm, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)

# Execute
response = agent_executor.invoke({
    "input": "Search for information about climate change"
})

Configuration

Environment Variables

export MESH_API_KEY="your-api-key-here"
export MESH_BASE_URL="https://api.meshcore.ai"  # Optional, defaults to official API

Client Configuration

from mesh_sdk import MeshClient

client = MeshClient(
    api_key="your-api-key",
    base_url="https://api.meshcore.ai",  # Custom API endpoint
    timeout=60.0,  # Request timeout in seconds
    max_retries=3,  # Max retries for failed requests
    retry_delay=1.0  # Base delay between retries
)

Error Handling

The SDK provides specific exceptions for different error scenarios:

from mesh_sdk import MeshClient
from mesh_sdk.exceptions import (
    AuthenticationError,
    AuthorizationError, 
    RateLimitError,
    ValidationError,
    APIError,
    NetworkError,
    TimeoutError
)

client = MeshClient(api_key="your-api-key")

try:
    agents = client.list_agents()
except AuthenticationError:
    print("Invalid API key")
except AuthorizationError:
    print("Access denied")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after} seconds")
except ValidationError as e:
    print(f"Invalid input: {e}")
except NetworkError:
    print("Network connection failed")
except TimeoutError:
    print("Request timed out")
except APIError as e:
    print(f"API error: {e}")

Logging

The SDK uses Python's standard logging module:

import logging

# Enable debug logging
logging.basicConfig(level=logging.DEBUG)

# Or configure specific logger
logger = logging.getLogger('mesh_sdk')
logger.setLevel(logging.INFO)
