Zero-dependency and lightweight — quotes, K-line, indicators & signals, screener & backtest, plus a CLI and a built-in MCP server for AI.
sdk.quotes.cn() / sdk.kline.cn() / sdk.options.etf.dailyKline() — organized by domain, no more flat long method names.
Zero runtime dependencies, runs in the browser and Node.js 18+; ESM + CJS with subpath imports.
A unified Quote model with base fields (symbol / market / timestamp / tz) — consistent units and a discriminated union.
14 built-in indicators plus a signal layer (golden/death cross, overbought/oversold), imported on demand from stock-sdk/indicators and stock-sdk/signals.
A declarative screener over market-wide quotes, boards and capital flow, plus a local, reproducible backtest engine.
The stock-sdk CLI fetches quotes from your terminal; stock-sdk mcp starts a built-in MCP server for AI tools — neither affects the main package size or its zero-dependency footprint.
