2.5 REST - IEX

2.5.1 Overview

Our IEX Exchange API has two kinds of avenues for (1) Customers who are officially registered with the exchange and (2) Customers who want a simple, compliant solution, but do not want to formally register with the exchange.

1. Tiingo has a cross-correct directly to the IEX Exchange that gives us access to raw binary price feeds we can share with you all. We receive IEX TOPS (top of book), which means we get the last sale data AND top bid and ask quotes.

2. For customers that don't want to register with the exchange to receive full TOPS, you may use our derived reference price feed which provides a real-time reference price for the asset - giving you the benefit of a real-time feed without the added compliance or exchange fees required.

Benefits of Tiingo + IEX

  • 14,000+ tickers IEX provides quotes and trade data on.
  • Data includes Top-of-Book (Bid/Ask) and Last Sale (trade) Data.
  • Data now includes intraday OHLC bar historical data for all your needs.
  • Tiingo enriches the data, giving you more data for your convenience.
  • Quotes updated to the latest nanosecond.
  • Access to every field IEX gives us access to (including trade flags).
  • Data is served via a REST API & Websocket API.

As of February 1st, 2025 IEX Exchange has changed their market data policies. To receive the FULL TOPS Feed, you must now have a market data agreement signed with the IEX Exchange. Upon signing, you will then be able to receive the full TOPS feed in real-time.

For customers who do not want to sign a license agreement, you may use our derived data that calculates a reference price for each asset in real-time. While this is not a subsitute for the TOPS Feed, we do believe it will fulfill the needs of 95% of our customer base. There is no additional cost to the IEX Exchange if using our derived data.

You can find out about the full product offering on the Product - IEX page.
