Application Programming Interface (API) is a method of extracting raw Semrush data without having to manually log into the software. Semrush offers two main API options:
Standard API Package (Analytics, Projects, Accounts APIs)
Traffic Analytics API
This API is available as an add-on to a Business subscription. The standard API package comes with three main APIs; Analytics, Projects, and Accounts APIs. When you add API to your subscription you will have a limited amount of API units that you can use to make calls. 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
Organic Research
Advertising Research
Keyword Gap Analysis
Keyword Analytics
Backlink Analytics
Projects API can pull data from Position Tracking and Site Audit campaigns created in Projects. Analytics and Projects API calls each have a cost in API units, which you will have a budget for when you purchase access to this API.
Accounts API can pull data such as your API export history, queries, and API unit balance. These calls will not charge you any API units.
See the full list of Semrush reports that API can pull here. Your API key can be found on your Subscription Info page.
Traffic Analytics API is available only to paid Semrush users and comes in 2 plans:
- Basic: provides only traffic summary data
- Extended: provides traffic summary data + 8 distinct reports
Basic API
Traffic Overview data will be able to show you estimates of a website's visitor behavior. These include monthly visits, unique visits, pages per visit, average visit duration, mobile vs. desktop traffic %, and bounce rate.
In the same way, the Traffic Analytics Overview report can compare up to 5 domains at a time, you can pull this 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.
Extended API
The extended API (full details in the API documentation) offers 8 distinct reports in addition to the Traffic Overview from the Basic API:
- Traffic Sources: the website traffic broken down into direct, referral, search, social, and paid traffic;
- Traffic Destinations: where users are going after visiting the domain you are looking at;
- Geographic Distribution: the countries, regions, or subcontinents where a website gets most of its visitors;
- Subdomains: the subdomains of the website that are responsible for acquiring the most traffic;
- Top Pages: the number of unique page views, unique visitors, entrances, and traffic sources for up to a site’s top 1000 pages based on traffic;
- Domain Rankings: top websites in the target location for the target period sorted by traffic;
- Audience Insights: additional visited domains, unique audience, shared audience %, and shared audience for the domains you entered;
- Data Accuracy: the estimated accuracy of the report based on the size of the domain and any filters you have applied (historical data, location, device).
The monthly limit rate included by default is 10,000 requests. This API does not use any API units associated with the standard Semrush API Package for Business subscriptions.
