yfinance

yfinance is the free-data workhorse — built on unofficial Yahoo endpoints that broke with the February 2025 redesign and have thrown YFRateLimitError waves into mid-2026. EventTrader's API is the boring alternative: documented endpoints, an issued key, published limits, and Tuatara signals you can't scrape anywhere.
