Historical Stock Data API

[Seanzy]

Does anyone know of a free API to obtain historical stock prices that are adjusted?

I’d try Yahoo Finance first. IB has an API too but it’s clunky, poorly documented, and likely overkill unless you are trying to build a trading bot. Sites like Koyfin have more data and I’m not sure if they have an API but it should be possible to scrape a few numbers from them using appropriate tools.
