Full-stack market data for US equities — 13 layers · 30+ endpoints · 11 sources · zero-auth · only
requests.Official-source-first (V2.0): CBOE options with full Greeks + 0DTE flow, FINRA market-wide short volume, SEC EDGAR filing stream + a free market-wide screener, Treasury / CFTC / earnings calendar. Every source is labeled with its compliance tier, terms quoted verbatim — "official" does not mean "free to use".
A single self-contained Skill file that turns raw US stock data — scattered across many sources — into a toolkit an AI coding assistant can call directly. You no longer memorize Eastmoney secid prefixes, Yahoo crumb auth flows, or SEC EDGAR CIK mappings. That's all handled.
This project distributes code, not market data. Data is fetched by the user under each source's own terms. For commercial use, rely only on tier-S sources.
Compatible with Claude Code · Codex · OpenClaw. The Skill file is structured Markdown + embedded Python — any AI coding assistant with context injection can use it.
