Messages are the fundamental units used to access data and make API calls on IEX Cloud. Every API endpoint has a “data weight” that indicates how many messages are used every time you make that API call.

The message system allows you to customize how you use your IEX Cloud subscription. You can use a higher volume of lower-weighted endpoints, fewer higher-weighted endpoints, or a combination.

IEX Cloud automatically keeps track of how many messages you have used and how many remain with your plan in your IEX Cloud Console. Before getting started, check out our API documentation to see how many messages are needed for the data you want to use.

Each IEX Cloud plan includes a monthly allocation of core messages, or a set number of messages that are automatically included with your subscription, as well as a designated set of tools and available datasets. Higher plans offer a cheaper cost-per-message, a larger core number of messages, and a broader set of tools and data.

You can determine which plan is right for you by approximating how many messages you will need on a monthly basis. Estimate your monthly usage by first choosing the data you would like to use, referencing those endpoints’ message weightings in our documentation, and taking into account how frequently you will request this data.

If you use all your core messages, you can continue accessing data using pay-as-you-go messages.

You can request to upgrade, downgrade, or cancel at any time in the IEX Cloud Console. Upgrades will be applied to your account immediately and are charged for the current month on a prorated basis.

Downgrades and cancellations will be applied to your account at the end of the month for monthly users and at the end of the annual billing cycle for annual users. We are unable to provide prorated refunds for downgrades or cancellations.

Core Data, such as stock data, cryptocurrency data, and FX data, can be accessed using the messages that you are allocated as part of your monthly subscription. If you run out of messages for the month, you can pay for Core Data at the pay-as-you-go rate.

Premium Data is specialized data sourced from various Data Partners, made available through the IEX Cloud API separately from our Core Data. Premium Data cannot be accessed using the messages you are allocated automatically through your subscription and uses the pay-as-you-go rate included with your IEX Cloud plan. To enable access to Premium Data, go to the Premium Data tab in the IEX Cloud Console.

Both Core and Premium data have designated message weighting that can be found in our documentation.

If you purchase a plan or upgrade mid-month, you pay a prorated amount based on when you purchased your new plan in the current calendar month. Your cost-per-message and core messages will be immediately updated to the reflect your new plan. Moving forward, your core message allocations will reset at the upgraded plan’s level at the beginning of each calendar month.
