yfinance

Provides intuitive classes like Ticker and Tickers that abstract HTTP requests, allowing data fetching with minimal code, as shown in the clean API examples in the README.

Supports historical prices, dividends, splits, real-time streaming via WebSocket, and market screening tools, covering most financial analysis needs without requiring multiple libraries.

With high PyPI download counts and regular updates, the library is well-maintained by contributors, and the new documentation website indicates ongoing development.

Unlike paid services, yfinance is completely free to use and modify, lowering barriers for research and education, as emphasized in its Apache license.
