IEX Cloud includes a breadth of data through a single easy-to-use API - ranging from simple stock prices for everyday investing, to Premium Data for more specialized use. 

This guide provides more detail on how Premium Data differs from Core Data and how to get started. 

Core Data vs. Premium Data

Core Data is the data included with IEX Cloud subscriptions. This includes any endpoints listed outside of the Premium Data section in our API documentation, such as stock data, cryptocurrency data, FX data, macroeconomic data and more. The credits (previously called messages) allocated with the IEX Cloud subscription can be used towards Core Data only. 

Premium Data is specialized data made available through the IEX Cloud API, sourced from various Data Partners directly. Premium Data consumption is on a pay-as-you-go basis using Premium Data credits, with different credit weights for each specific dataset. Premium Data is not included in the base IEX Cloud subscription.  

Premium Data is available to all customers with a paid plan on IEX Cloud. 

How do I start using Premium Data?

Follow the steps below to access Premium Data:

  1. Log into your paid IEX Cloud account. If you're new to the platform or currently on a free plan, sign up for an Individual or Business plan to access Premium Data.

  2. Add Premium Data credits to your account on the add-ons page. Premium Data usage is purchased with prepaid Premium Data credits. Learn more here in our Help Center, and purchase Premium Data credits here.

  3. Request access to data on the Premium Data page of the IEX Cloud Console. For many datasets, you'll be granted access right away. However, a couple require partner approval and it could be a few business days before your access is activated. You can request access here.

    Once the Data Partner that provides that dataset confirms your request, it will be marked as “Enabled."  

  4. Start accessing data! Your account will then be able to successfully make API requests to the dataset’s endpoints. You can start and stop using Premium Data at any time.  

Be sure to check Premium Dataset endpoints’ data weights before use. The endpoints for Premium Data and their weighting are documented here

Please note that each Data Partner has its own unique protocol for processing data access requests. You may be asked to complete a couple of extra steps or experience wait times when confirming access for different datasets.  

Pricing for Premium Data on IEX Cloud

Premium Data is available as an addition to the Core Data already accessible through the IEX Cloud subscriptions, and uses Premium Data credits. For legacy Launch, Grow, and Scale plan users, it also uses pay-as-you-go credits. Credits included with the IEX Cloud subscriptions are used for Core Data and cannot be used towards Premium Data. 

Premium Data makes it easy to access a wider range of financial data and alternative data all in one place. Premium Data may be priced higher than other endpoints used as a part of the IEX Cloud Core Data offering, as it provides curated, specialized data sourced directly from other data creators.   

How much data usage do I get with each dollar of Premium Data credits?

When you purchase Premium Data credits, you’ll notice that you purchase in dollar amounts. Our Premium Data endpoints, on the other hand, are priced in credits. For instance – you might purchase $50 worth of Premium Data credits, with the plan of using a Premium Data endpoint with a data weight of 100,000 credits per API call.

For our Business and Individual plans, you purchase credits for Premium Data use at $1 per 1 million credits. For instance, $20 would provide 20,000,000 credits.

For our legacy plans, the dollar-to-credit conversion depends on your plan. Premium Data is charged at the cost of your pay-as-you-go credit rate:

  • Launch: $1 per 1 million credits

  • Grow: $1 per 2 million credits

  • Scale: $1 per 3 million credits

What is the monthly credit budget on Premium Data use? (Legacy Launch, Grow, and Scale plans only)

Credit budgets are the same as message budgets.

With legacy Launch, Grow, and Scale plans that use pay-as-you-go credits, IEX Cloud allows you to set customizable limits for the number of credits used on Premium Data per month. Credit budgets can be used to help maintain a cap on your credits consumption for the month or prevent accidental runaway use of Premium Data. 

A default budget of 100,000,000 credits is set when you enable access to your first dataset. When this limit is reached, access to Premium Data will be paused until the end of the month or until the limit is modified. You can change this limit at any time in the IEX Cloud Console.
