IEX here. Thanks for mentioning our API. We are excited to see what everyone will build. Just to reiterate, the API is free for personal and commercial use, doesn't require an API key, and is reliable enough to drive our own applications.

Real time quotes and trades are available from our own market data, but we also provide market wide prices (SIP) on 15 minute delay in addition to the company info mentioned above.

We are very actively developing the API, and will continue to improve data sets, features, and performance. If you experience any issues we have community support at https://github.com/iexg/IEX-API/issues which we actively monitor.

Thanks for building this! I noticed that the charting api have EOD prices for past 5 years, is there a plan to support longer durations?

We are currently working on new datasets including EOD data for the past 20 years. Our market data is available now through REST and WebSockets, but we are working on adding more data via WebSocket, and introducing HTTP streaming in the near future.
