Wrapping Your Agent as HTTP Server

The SDK provides AgentArtsRuntimeApp to wrap your agent logic as a standard HTTP server, exposing:

• POST /invocations - Main agent invocation endpoint
• GET /ping - Health check endpoint
• WS /ws - WebSocket endpoint for streaming

Example: LangGraph Agent

# agent.py
import os
from typing import Dict, Any, TypedDict, Annotated
from operator import add

from agentarts.sdk import AgentArtsRuntimeApp, RequestContext

app = AgentArtsRuntimeApp()


class State(TypedDict):
    messages: Annotated[list, add]
    query: str
    response: str


class LangGraphAgent:
    def __init__(self):
        self.model_name = os.environ.get("OPENAI_MODEL_NAME", "gpt-4o-mini")
        self._graph = None

    def _build_graph(self):
        from langgraph.graph import StateGraph, END
        from langchain_openai import ChatOpenAI
        from langchain_core.messages import HumanMessage, AIMessage

        llm = ChatOpenAI(
            model=self.model_name,
            api_key=os.environ.get("OPENAI_API_KEY"),
            base_url=os.environ.get("OPENAI_BASE_URL")
        )

        async def process_node(state: State) -> Dict[str, Any]:
            query = state.get("query", "")
            messages = state.get("messages", []) or [HumanMessage(content=query)]
            response = await llm.ainvoke(messages)
            return {
                "messages": [AIMessage(content=response.content)],
                "response": response.content,
            }

        workflow = StateGraph(State)
        workflow.add_node("process", process_node)
        workflow.set_entry_point("process")
        workflow.add_edge("process", END)
        return workflow.compile()

    async def run(self, query: str) -> Dict[str, Any]:
        graph = self._graph or self._build_graph()
        self._graph = graph
        result = await graph.ainvoke({"messages": [], "query": query, "response": ""})
        return {"response": result.get("response", "")}


_agent = LangGraphAgent()


@app.entrypoint
async def handler(payload: Dict[str, Any], context: RequestContext = None) -> Dict[str, Any]:
    query = payload.get("message", "")
    return await _agent.run(query)


if __name__ == "__main__":
    app.run()

Key Points

1. Focus on Agent Logic - You only need to implement the agent logic; the SDK handles HTTP server, request parsing, and response formatting
2. Framework Agnostic - Works with any agent framework (LangChain, LangGraph, AutoGen, CrewAI, or custom implementations)
3. Simple Decorator - Use @app.entrypoint to mark your handler function
4. Context Support - Optional RequestContext parameter provides session info and request metadata
5. Configurable Model - Model name can be configured via environment variable (e.g., OPENAI_MODEL_NAME)

Installation

Requirements

• Python 3.10 or higher
• pip or uv package manager

Create Virtual Environment (Recommended)

It is recommended to install the SDK in a virtual environment to avoid dependency conflicts.

Windows:

# Create virtual environment
python -m venv venv

# Activate virtual environment
.\venv\Scripts\Activate.ps1

# Or using Command Prompt
.\venv\Scripts\activate.bat

Linux/macOS:

# Create virtual environment
python -m venv venv

# Activate virtual environment
source venv/bin/activate

Install via pip

Windows:

pip install agentarts-sdk

Linux/macOS:

pip install agentarts-sdk

Install with Optional Dependencies

# With LangChain support
pip install agentarts-sdk[langchain]

# With LangGraph support
pip install agentarts-sdk[langgraph]

# With all optional dependencies
pip install agentarts-sdk[all]

Install from Source

Windows:

git clone https://github.com/huaweicloud/agentarts-sdk-python.git
cd agentarts-sdk-python

# Create and activate virtual environment
python -m venv venv
.\venv\Scripts\Activate.ps1

# Install in development mode
pip install -e ".[dev]"

Linux/macOS:

git clone https://github.com/huaweicloud/agentarts-sdk-python.git
cd agentarts-sdk-python

# Create and activate virtual environment
python -m venv venv
source venv/bin/activate

# Install in development mode
pip install -e ".[dev]"

Configure Huawei Cloud Credentials

Set environment variables for Huawei Cloud authentication:

Windows (PowerShell):

$env:HUAWEICLOUD_SDK_AK = "your-access-key"
$env:HUAWEICLOUD_SDK_SK = "your-secret-key"

Windows (Command Prompt):

set HUAWEICLOUD_SDK_AK=your-access-key
set HUAWEICLOUD_SDK_SK=your-secret-key

Linux/macOS:

export HUAWEICLOUD_SDK_AK="your-access-key"
export HUAWEICLOUD_SDK_SK="your-secret-key"

Note: Get your AK/SK from Huawei Cloud Console -> My Credentials -> Access Keys.

For complete environment variable configuration, see Environment Variables Guide.

Quick Start

1. Initialize a New Project

# Create a new agent project with LangGraph template
agentarts init -n my_agent -t langgraph

# Available templates: basic, langchain, langgraph, google-adk

This creates:

my_agent/
├── agent.py              # Agent implementation
├── requirements.txt      # Python dependencies
├── .agentarts_config.yaml # Project configuration
└── Dockerfile            # Docker build file

2. Configure Environment

Edit .agentarts_config.yaml to set environment variables:

runtime:
  environment_variables:
    - key: OPENAI_API_KEY
      value: "your-openai-api-key"
    - key: OPENAI_MODEL_NAME
      value: "gpt-4o-mini"  # Optional: gpt-4o, gpt-4-turbo, etc.
    - key: OPENAI_BASE_URL
      value: ""  # Optional: custom API endpoint

3. Local Development

# Start local development server
agentarts dev

# Server runs at http://127.0.0.1:8080
# Endpoints:
#   POST /invocations - Invoke agent
#   GET  /ping        - Health check

4. Deploy to Huawei Cloud

# Configure region
agentarts config set region cn-southwest-2

# Deploy to cloud
agentarts deploy

# Invoke deployed agent
agentarts invoke '{"message": "Hello, AgentArts!"}'

# Destroy deployment
agentarts destroy
