Overview

The Yahoo Finance News Tool fetches the latest headlines and market data for any stock symbol directly from Yahoo Finance. It’s perfect for finance-related agents and applications that require real-time insights before making decisions.

How It Works

Under the hood, the tool scrapes Yahoo Finance’s News page for your specified symbol (e.g., “NVDA”) and returns:
  • Top headlines
  • A brief summary of price movements and key financial metrics
This tool makes live HTTP requests to Yahoo Finance. Excessive usage may trigger rate limiting or IP bans.
