Why and when it is better to choose the service
    IVolatility API offers two tiers of data that are designed for two different kinds of use-cases.

    The first tier is geared towards real-time data users. In the entry-level version, users will have access to unlimited delayed stocks and equity options data that includes NBBO, open interest, and volume. The full version includes unlimited real-time stocks and options data, and, additionally, implied volatility and greeks. Both delayed and real-time packages include limited access to trial historical daily and intraday data.

    The second tier is intended for users who work with historical data, in which IVolatility offers the base and extended Rest API packages. Both packages provide access to unlimited end-of-day stocks and options data. The extended package also includes implied volatilities and greeks, as well as additional datasets, such as implied volatility surface (IVS) and IVX - IVolatility's proprietary volatility index. Moreover, with a 1000 intraday monthly request limit, the base package also offers users to trial historical intraday data. If the user is satisfied with the quality of IVolatility's intraday data, s/he may upgrade to the extended historical data package, which raises the monthly intraday limit to 100k requests.
