Marketstack

What is Marketstack?

Marketstack is a REST API that delivers real-time, intraday, and end-of-day stock market data, plus EDGAR SEC filings, in lightweight JSON format. It solves the problem of accessing reliable, scalable financial data without managing complex infrastructure — perfect for developers, financial analysts, and fintech startups.

Who is it for?

Marketstack is built for developers integrating stock data into apps, traders needing intraday quotes, researchers pulling historical data, and compliance teams retrieving SEC filings. It is not a trading platform or portfolio manager — it is a data API only.
