Can I use and distribute data from IEX Cloud in commercial applications?
Users on the Start plan are only permitted to use data from IEX Cloud for personal, non-commercial use. Paid plan users can use IEX Cloud data for commercial use, including displaying publicly to users.
No user may provide IEX Cloud data via their own API to users, or provide a mechanism for mass downloads, for example as a CSV. For more information please see our terms of service.
Attribution is required for all users. It is as simple as putting “Data provided by IEX Cloud” somewhere on your site or app and linking that text to https://iexcloud.io.
