Project overview

yahoo-finance2 is an unofficial JavaScript API for retrieving quotes, charts, historical data, options, company summaries, screeners, and other Yahoo Finance results. Developers can call it as a library, use its command-line interface, or optionally expose the same tools through MCP and the bundled Agent Skill. It supports Node.js, Bun, Deno, and compatible Cloudflare runtimes, but it cannot run directly in a browser because of CORS and cookie constraints. Yahoo does not guarantee API availability or consistency.
