## What it is
Official sample code repository from Korea Investment & Securities for their Open Trading API (KIS Developers), providing Python examples for REST and WebSocket access to domestic/overseas stocks, bonds, futures, options, and ETFs. It includes LLM-organized example code, a visual strategy builder, a backtesting engine, and MCP tooling so both human developers and AI agents can build automated trading workflows.

## Use cases
- build an automated stock trading bot with Korea Investment Securities API
- fetch real-time stock prices via websocket in Python
- place buy and sell orders for Korean and overseas stocks programmatically
- let ChatGPT or Claude call brokerage trading APIs via MCP
- backtest a trading strategy on historical market data
- get access token authentication for KIS Open API
- query bond, ETF, and futures prices from a brokerage

## When to choose
- you have a Korea Investment & Securities account and API keys
- you want official, maintained Python examples for KIS Developers endpoints
- you want LLM/AI-agent-friendly code structure or MCP integration for trading
- you need both REST and WebSocket examples across many asset classes

## When to avoid
- you trade with a different broker whose API this does not wrap
- you need a production-grade trading framework with guaranteed support - samples are reference code with no warranty
- you need a permissively licensed library - the repo has no explicit license
