IEX retires IEX API, TOPS Viewer, and Stocks Applications
Effective November 19, 2021, IEX Exchange will retire the internet-based data products (i.e., IEX API, TOPS Viewer, Stocks application) that it currently publishes in parallel with its direct market data feeds.
IEX has proposed to retire the Data Platform because IEX has determined that because IEX offers the same data in the Data Platform through other data products, the costs associated with maintaining and updating the Data Platform outweigh the benefits of offering the Data Platform.
IEX provides all of the data available in TOPS Viewer and the API through other market data products. Specifically, IEX’s “TOPS” feed contains all the data visible in the TOPS Viewer, and IEX’s “DEEP” feed contains all the data accessible via the API. Additionally, IEX’s “HIST” offers TOPS and DEEP data on a T+1 basis for download from the Exchange’s public website.
