yfinance

A popular open source Python library that provides a reliable way to download historical market data and financial statements from Yahoo Finance.

yfinance is the go to tool for developers needing quick access to market data without the overhead of a formal institutional subscription. Created by Ran Aroussi, this library wraps Yahoo Finance's public APIs to deliver historical price data, dividends, and stock splits directly into Pandas DataFrames. It handles complex tasks like ticker lookups (e.g., MSFT or AAPL) and multi-ticker downloads with a single line of code: yf.download. While it is an unofficial tool, its ability to fetch everything from intraday 1 minute intervals to 30 plus years of daily history makes it a staple for financial prototyping and algorithmic backtesting.
