Let’s dive into why developers, fintech startups, and global enterprises choose Marketstack and how it’s helping to shape the future of finance.
Why Financial Applications Need a Robust Stock Market API
Before we get into the details, let's talk about why financial APIs are critical today.
A powerful stock market API enables you to:

Access Historical Market Data: Analyze long-term trends and build smart algorithms.
Simplify Financial Data Collection: No need to scrape websites or rely on unstable sources.
