Get started

Your API key lets you send requests through the Semrush API.

To get your key:

1. Click the icon at the top right of the Semrush interface to access your account.
2. Select Subscription info and go to the API Units tab.
3. Copy your API key.

When running an API request, each particular line will cost API unit*.
The total amount of units that you will need to spend per request will depend on the exact number of lines in the report.

Make sure that you have a sufficient number of API units: within the Subscription info tab or via API request (Check API unit balance).

*Billing Traffic analytics API works differently, read more here.

Each report type provides an example of a request. This is a great starting point for your own requests.

1) Begin with the base URL. It depends on the product

2) Enter ?key followed by you API key

3) Enter report type

4) Enter request parameters

5) Enter the domain name

6) Enter the database

Certain types of reports within Semrush API have “display_limit”. Display limits are used when the report you are pulling data from analyzes data in specific order

Use display_limit to limit the amount of lines to save API units

Example:

Adding “&display_limit=10” will limit your request to the top 10 results.

If you recive an error code saying there was a problem within your API request, refer to the Error page to view description that will help to fix the problem.
