Data API

Access all the industry standard options data and a plethora of proprietary data, including forecasts, implied volatility summaries, and historical volatility readings. We offer both delayed and historical end-of-day and intraday (one minute) options data, all accessible through a RESTful API call.

Industry Leading Data

Unparalleled Data Quality

Every day since 2007, we’ve taken a snapshot 14 minutes before the close of all bid asks of all standard options and accompanying stock prices. We process all this data through our Smoothed Market Values (SMV) system, producing the best greeks and theoretical values.

Hundreds of Proprietary Indicators

With over 15 categories of data, we calculate component weighted averages, forward and flat volatilities, contango, constant maturity implied volatilities, and much more.

Organized Around REST

Our API is designed to have predictable, resource-oriented URLs and to use HTTP response codes to indicate API success and errors. We process over 100,000 requests per day, and offer a flexible pricing structure so you only pay for what you need.

Data API
