Data to light your path.

Yes, we provide pre-market and after-hours data. Live quotes cover the IEX extended session, which runs from 8:00–9:30 AM and 4:00–5:00 PM ET (shorter than the full extended trading hours available on other exchanges). For the full pre- and post-market day, our candles data includes all activity reported by the official exchanges (SIPs). You can access this through the API or directly in Google Sheets using our add-on.

We offer historical stock and options data and going back to 2010. For some stocks, data may be available further back, depending on the symbol.

Our self-service plans are designed for personal and internal use. If you'd like to use Market Data for commercial purposes, redistribution, or public display, we'll work with you to find the right option for your use case and budget. Depending on your needs, exchange licenses may also be required. Please contact our sales team to get started.

All plans use the same high-quality data sources, but access levels vary.

Free plans are limited to historical data only. You can't access today's data, and yesterday's data becomes available after the market opens the following trading day at 9:30 a.m. Eastern Time. Historical access is also limited to a maximum of one year.

Paid plans include access to real-time and/or 15-minute delayed data, depending on the plan you choose. You'll also get access to the current day's data and historical coverage beyond one year.

Example: If today is Tuesday, free users can access Monday's data starting at 9:30 a.m. ET on Tuesday.

Yes, our low-cost Starter Plan includes 15-minute delayed options data—ideal for users who don't need real-time access to options and want to keep costs down. It includes access to a wide range of asset classes, including stocks, options, and mutual funds, making it a great entry point for personal projects or research.
