Click the icon at the top right of the Semrush interface to access your account.
Select Subscription info and go to the API Units tab.
Select an API unit package and click Buy more.

How many API units do you need?

The cost of requests is measured in units. Units are determined by the type of report or request. Delivering historical data from the analytics tools requires more units than live data.

For example, one line of response in the Domain Organic Search Keywords report costs 10 units for live results and 50 units for historical data. If you’d like to list 1,000 organic keywords for 100 domains, you will be charged for 1,000,000 and 5,000,000 units, respectively (1,000 keywords * 10 API units for live data * 100 domains = 1,000,000 units; 1,000 keywords * 50 API units for historical data * 100 domains = 5,000,000 units).

We recommend calculating your API request limit before purchasing an API unit package. You can increase your request limit by purchasing API units.

Note that you don’t need to buy API units to use the Listing Management API. It’s available for all Semrush Local Premium Plan users.
