Python Starter Agent

A minimal Python LLM Agent template on EdgeOne Makers — built on raw httpx against an OpenAI-compatible Chat Completions endpoint, with EdgeOne sandbox tool calling and context.store-backed conversation memory. No agent framework.

Framework: None (raw Python) · Category: Quick Start · Language: Python

Overview

The smallest reasonable starting point if you want a Python chat Agent without committing to a framework. The whole loop — prompt → stream LLM → execute tool calls → loop → final answer — is plain httpx and a small tool_registry. Read the source top-to-bottom and you've seen everything.

• SSE streaming chat — token-by-token push of text_delta, plus tool_called events.
• EdgeOne sandbox tools — commands, files, code_interpreter, browser are pulled from context.tools and exposed as OpenAI function calling tools.
• Tool-calling loop — up to 10 rounds: model returns tool_calls → execute via tool_registry.execute() → append results → re-request, until a final answer.
• Conversation memory — ChatSession(context.store) reads/writes per-conversation history via the EdgeOne store.
• Honest cancellation — frontend AbortController plus backend context.request.signal actually release the upstream LLM connection.

Environment Variables

Variable	Required	Description
AI_GATEWAY_API_KEY	Yes	Model gateway API key. Use your Makers Models API Key, or any OpenAI-compatible provider key.
AI_GATEWAY_BASE_URL	Yes	Gateway base URL. For Makers Models, use https://ai-gateway.edgeone.link/v1.
AI_GATEWAY_MODEL	No	Model ID. Defaults to @makers/deepseek-v4-flash (a free built-in model).
WSA_API_KEY	No	Tencent Cloud Web Search API key. Required only if you use the web-search tool.

This template follows the OpenAI-compatible standard — point these at Makers Models or any compatible provider.

How to get AI_GATEWAY_API_KEY

1. Open the Makers Console.
2. Sign in and enable Makers.
3. Go to Makers → Models → API Key and create a key.
4. Copy it into AI_GATEWAY_API_KEY.

The built-in @makers/deepseek-v4-flash model is free with a usage cap and is suitable for prototyping. For production, bind your own paid provider (BYOK).

How to get WSA_API_KEY

WSA_API_KEY is only needed when calling the web-search tool. See the documentation.
