Intro
Semrush offers the following API options:
- Standard API
- Trends API
- Listing Management API
- Map Rank Tracker API
Standard API
Standard API access is available to users of the SEO Toolkit who have a Business subscription.
1. Upgrade to SEO Business plan
- Go to the Pricing page.
- Upgrade to the SEO Business plan to buy API units and generate an API key.
Note that after upgrading to the SEO Business plan the number of units will still be zero.
2. Buy API unit package
Now you can buy API units according to your needs:
- 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.
3. Copy API key
Once you have purchased API units, copy your API key to use it in your API requests:
Trends API
The Trends API comes in two plans:
- Trends Basic API offers access to broad traffic summaries that include website traffic metrics and user behavior data. Ideal for marketers focused on analyzing competitor web traffic, benchmarking traffic statistics, and understanding user behavior on competitor domains.
- 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.
To learn more about Trends Basic API and Trends Premium API, refer to Trends API subscription plans.
Get access to Trends API
If you don’t have a Semrush subscription:
- You can buy access to Trends API Basic directly from this page.
- For Trends API Premium, contact the Sales team using the Sales Inquiry form. The team will provide you with a personalized quote that fits your needs.
If you already have access to the Trends API, you can purchase additional API units directly from the Subscription info page.
The monthly limit rate included by default is 10,000 requests. The Trends API doesn't use Standard API units.
You can always upgrade your plan from Basic to Premium or increase your limits by choosing the corresponding option on the Subscription info page.
