Summary This project offers a unified, zero-authentication toolkit for US and Hong Kong stock data, targeting AI coding assistants and technical users. It consolidates data from five sources (Sina, Tencent, Eastmoney, Yahoo, SEC EDGAR), abstracting authentication and parsing complexities to simplify financial data retrieval.

How It Works An 8-layer architecture integrates data via direct HTTP API calls, minimizing dependencies to requests. It automatically handles Yahoo's crumb authentication and uses a standard User-Agent for SEC EDGAR, eliminating the need for API keys. Technical indicators are computed in pure Python.

Quick Start & Requirements

1. Create directory: mkdir -p ~/.claude/skills/global-stock-data
2. Download SKILL.md: curl -o ~/.claude/skills/global-stock-data/SKILL.md https://raw.githubusercontent.com/simonlin1212/global-stock-data/main/SKILL.md
3. Install dependency: pip install requests

The skill integrates seamlessly with AI assistants like Claude Code. Codex/OpenClaw users can paste SKILL.md content into their system prompts.

Limitations & Caveats

• Hong Kong options data is unavailable.
• Users in mainland China may face instability accessing Yahoo/SEC; proxies or alternative sources are recommended.
• Sina's HK K-line data is reported as down.
• SEC EDGAR rate limits (10 req/sec) are managed by the tool's User-Agent.
