API

This API is available as an add-on to the Business tier of the SEO Toolkit subscription. The standard API option comes with Analytics and Projects APIs. Upgrading to the Business tier will give you an opportunity to buy API units and generate an API key.

Note that after upgrading to the Business tier, the number of units will still be zero. You should buy a suitable amount of API units according to your needs—note that the amount of units purchased becomes a part of your recurring subscription. If a certain amount of units is included in your subscription, it will renew on the same day as your plan. Unused units will expire instead of being added to the renewed amount.

Whenever you run out of units, you can buy more from the Subscription Info page or by contacting us.

• Analytics API allows you to pull data from Analytics reports including:

  • Domain Analytics 
  • Keyword Analytics 
  • Backlink Analytics

• Projects API can pull data from Position Tracking and Site Audit campaigns created in Projects. You can also manage your projects (create, update, or delete them, for example) with the help of the Projects API.

It is possible to get the subfolder, subdomain, and URL data via the API. Check the Subdomain, Subfolder, or URL section in the API Documentation to see what reports you can pull data from.

Analytics and Projects API calls each have a cost in API units. The total amount of units that you will need to spend will depend on the type of request or the exact number of lines in the report.



You can check your API units balance either within the Subscription info tab or via a free API request (API units balance).

Trends API (Traffic & Market Toolkit data) is available only to paid Semrush users and comes in 2 plans:

• Trends Basic API: Offers access to broad traffic summaries that include website traffic metrics and user behavior data
• Trends Premium API: Offers everything included in the Trends Basic API, along with 16 additional data types that allow you to dig deeper into market dynamics, competitor strategies, and web traffic flows 

Trends Basic API

The Trends Basic API provides estimates of a website's traffic and visitor behavior. These include monthly visits, unique visits, pages per visit, average visit duration, mobile vs. desktop traffic %, bounce rate, and a domain's category.

You can pull traffic data for up to 200 domains in a single request using the Summary reports. This data gives you a quick look into the general level of interaction between a website and its visitors.

Trends Basic API calls work for root, subdomains, and subfolders except for Traffic Rank, Audience Insights, and Data Accuracy.
