Introduction

Semrush API (Application Programming Interface) is a method of extracting raw Semrush data without manually logging into the platform. It empowers marketers, analysts, and developers to automate insights and seamlessly integrate Semrush data into their own systems and workflows.

More than just an SEO audit API, Semrush API:

• Provides access to a comprehensive ecosystem of data—from SERP insights, such as keyword rankings and backlinks, to website traffic, including AI search traffic data from AI-powered search engines and assistants like ChatGPT, Gemini, and Copilot.
• Delivers website audience insights, key traffic channels, and market trends, enabling you to evaluate your domain performance across industries.
• Supports local listing management, helping you maintain consistent business information across locations and track your location ranking on Google Maps.

API access is available on paid Semrush plans. Each API request consumes a specific number of API units depending on the endpoint and your plan. For details, refer to the Pricing page or contact our sales representatives.

Semrush provides APIs for several Semrush toolkits:

Two Semrush API versions are available: version 3 and version 4.

The main difference between versions is the authorization method, availability of major changes inside the feature APIs, and list of available feature reports.

Each version consists of product groups, products themselves, and product reports.

Semrush APIs return data in different formats depending on their version and purpose.

Semrush offers the following API options:

• Standard API
• Trends API
• Listing Management API
• Map Rank Tracker API

To learn how to start using the API, refer to How to get API.

Standard API consists of the Analytics (version 3) and Projects APIs (version 3 and version 4).

This API is available as an add-on to a Business subscription. Additionally, to make API calls, you need API units that are purchased separately. To learn more, refer to Standard API.
