Simple REST API for end-of-day, intraday and real-time stock prices on global exchanges, with a free 100-request plan and paid plans from $9.99 a month.
What it is
Marketstack, an APILayer product, is a JSON REST API for stock prices. Its core is end-of-day data for tickers on exchanges worldwide, with 750+ market indices, splits and dividends, and exchange, currency and timezone reference data. Paid plans add intraday prices for US stocks sourced from the IEX exchange, bonds, ETF holdings and, on the higher tiers, real-time prices, commodities and company fundamentals. Six SEC EDGAR endpoints for 10-K, 10-Q and 8-K filings were added recently. It does not offer options data.
Plans differ mainly by monthly request allowance and history depth. The free plan is 100 requests a month, end-of-day only, one year of history and non-commercial use. Basic adds 10,000 requests, 10 years of history, commercial use and IEX intraday data. Intraday intervals shorter than 15 minutes, which Marketstack calls real-time updates, start with Professional; Business adds company ratings, statements and facts.
Usage is counted per symbol, not per call: each ticker in a request uses one request, so a 100-symbol query uses 100. Paid plans bill overage per extra request instead of cutting you off. Intraday history is limited to the last 10,000 data points per interval. Version 1 of the API was deprecated after June 30, 2025, and new features are documented for version 2 only.
