About

Marketstack is a straightforward API for historical and end-of-day stock data from exchanges around the world. You can use it to chart a stock's price history over the past year, to build a simple portfolio returns tracker, or to back-test a basic trading idea on daily data. The free plan only includes end-of-day data (no live intraday prices) and a small monthly request budget, so it suits casual tracking more than active trading.

Details
