Use IEX Cloud Core Financial Data#

IEX Cloud comes with 5+ terabytes of production-ready financial data to power fintech applications. It includes real-time financial data and historical time series financial data. Both data types are described here.


We are in the process of migrating legacy IEX Cloud Core Data to IEX Cloud Core Datasets in Apperate. IEX Cloud’s API reference is currently split between Apperate’s API Reference and the Legacy API Reference. If the API Reference doesn’t list the data you want, please check the Legacy API Reference.

Real-Time Financial Data#

The Legacy API Reference describes everything you need to get IEX Cloud real-time financial data.

Here’s an overview:

Each endpoint reference includes the HTTP request structure, data weighting (for legacy plans), data timing and schedule, data sources, examples, path/query parameters, and response attributes.

To start calling these endpoints, see Get Real-Time IEX Cloud Core Financial Data.

Historical Financial Data#

Apperate’s built-in historical time series data is available as datasets (a.k.a. Core Datasets) that you can query and join with other datasets to create views. The datasets are available in the console at Data → Datasets → Core and in the API Reference at IEX Cloud Core Datasets.

In the console, each dataset Overview page provides an example request URL that you can click to get data from the dataset.


A dataset’s Database page (the tab is next to Overview) provides a SQL editor for querying the dataset and joining with data from other datasets to create views.

The Overview page’s Open Docs button opens the dataset’s GET /data endpoint reference page.

You can query the dataset using the GET /data parameters.

Now you’re familiar with Apperate’s core financial data.

Upgrade to Access All Core Data#

If you’re using Apperate via the free trial plan, some Core datasets are inaccessible (see the grayed-out datasets in the image below).

You can access these datasets by upgrading to a paid plan. To upgrade, click one of the grayed-out datasets and click the Upgrade button that appears in the window (see image below).

Alternatively, you can upgrade your plan at AccountManage Plan.

What’s Next#

Data Bundles describes each of the data bundles and links to their REST endpoint docs and guides to start using those endpoints.

Get Real-Time IEX Cloud Core Financial Data demonstrates querying real-time financial data.

Get Historical IEX Cloud Core Financial Data shows how to get historical time series financial data.

Normalized Financial Symbols shows how to query on and join datasets on financial symbols using any supported financial identifier type.
