Struggling to manage all your SEO data manually? If you’re anything like me, you probably wish there was a way to pull all that valuable information from Semrush straight into your own tools or custom dashboards without clicking around for hours. Well, good news! The Semrush API documentation is your golden ticket to automating so much of your digital marketing workflow. It’s like having a direct line to Semrush’s massive database, letting you pull specific data points and integrate them into whatever system you’re using, whether it’s for reporting, competitor analysis, or even building your own custom SEO tools.
This guide will walk you through everything you need to know about the Semrush API, from what it is and why you’d want to use it, to understanding its pricing and even getting started with a practical Python example. We’ll even cover the different types of APIs Semrush offers and tackle questions like “is Semrush free” when it comes to API access. By the time we’re done, you’ll have a clear picture of how to leverage this powerful tool to make data-driven decisions faster and more efficiently, ultimately boosting your SEO efforts and saving you a ton of time.
What Exactly is the Semrush API?
Think of the Semrush API, or Application Programming Interface, as a special bridge. It’s a software intermediary that lets different applications talk to each other directly. Instead of you logging into the Semrush website, navigating through reports, and manually exporting CSVs, the API lets your own software — maybe a custom script, a dashboard, or even another marketing tool you’re building — request and receive Semrush data automatically.
It’s essentially programmatic access to Semrush’s incredible wealth of data and tools. This means you can integrate Semrush functionalities right into your applications, websites, or internal systems, unlocking automation and advanced analysis possibilities that just aren’t as straightforward with the standard user interface.

Why Bother with the Semrush API? Beyond Manual Reporting
So, why would you, a busy marketer, developer, or agency owner, care about an API? Simply put, it changes the game for how you handle SEO data. Here’s why it’s a big deal:
- Automation is Your Friend: Remember those repetitive tasks like pulling keyword research data every month, checking backlink profiles for new links, or running site audits? The API lets you automate all of that. You can set up scripts to fetch data regularly, freeing you up to focus on strategy instead of manual data collection. For example, you can schedule API calls to grab keyword data weekly, helping you spot trends and opportunities without even thinking about it.
- Customization is King: The standard Semrush interface is fantastic, but what if you need data presented in a very specific way for your clients or internal teams? With the API, you can pull raw data and build custom dashboards, reports, and tools that perfectly fit your needs. Imagine creating a unique report that combines Semrush data with your analytics platform, all in one custom view!
- Efficiency on Steroids: Manually extracting and processing large datasets can be a real drag. The API streamlines your workflow, drastically cutting down the time it takes to get the information you need. This means quicker insights and faster decision-making.
- Scale Your Efforts: If you’re managing many websites or have massive data requirements, trying to do everything manually just won’t cut it. The Semrush API allows you to handle large volumes of data and perform complex analyses that would be incredibly cumbersome otherwise, making it ideal for scaling your SEO operations.
- Deeper Data-Driven Insights: By integrating Semrush data into your own systems, you can combine it with other data sources for even richer insights. This helps you make more informed decisions, enhancing your SEO strategy in ways that aren’t possible with isolated data.

The Core Components: What Data Does the Semrush API Offer?
Semrush doesn’t just offer one big, generic API. It actually provides several specialized APIs to cater to different needs and data types. Understanding these will help you figure out which one is right for your projects.
Standard API: Your SEO Powerhouse
This is probably what most people think of when they hear “Semrush API.” It’s the most commonly used option and is broken down into a couple of key areas:
- Analytics API: This is where you get a treasure trove of competitive intelligence. You can pull data on domains, keywords, and backlinks.
- Domain Analytics: Need to know how a competitor’s site is performing? You can grab data on their traffic, top keywords, organic search performance, paid search data, and even their advertising history. You can get insights into a domain’s organic search performance, including top keywords and traffic.
- Keyword Analytics: This is a goldmine for keyword research. You can retrieve essential keyword data like search volume, difficulty, CPC Cost Per Click, and competition. It helps you identify high-potential keywords with low competition, a real win for optimizing your SEO strategies. You can even perform bulk keyword research, pulling data for up to 50,000 keywords in a minute, complete with search volume, competition, and CPC.
- Backlink Analytics: Want to analyze a domain’s backlink profile? The API lets you get detailed backlink data, including referring domains, anchor text, and even run backlink audits to identify potentially harmful links. You can use metrics like Authority Score to gauge the reliability of backlinks.
- Projects API: This part of the API focuses on data related to your Semrush projects.
- Position Tracking: If you’re tracking keyword rankings for your site or competitors, you can automate this with the Projects API. This means getting daily updates on website position changes without manually checking reports.
- Site Audit: Need to keep an eye on your site’s technical SEO health? The Site Audit API lets you perform comprehensive site audits to identify issues.
The .Trends API: Unpacking Market Insights
The .Trends API is a separate beast, focusing more on market and traffic insights. It’s perfect if you’re trying to understand broader market dynamics or competitor strategies.
- Trends Basic API: This gives you access to broad traffic summaries, including website traffic metrics and user behavior data. It’s great for quickly analyzing competitor web traffic and benchmarking.
- Trends Premium API: If you need to dig deeper, the Premium version offers everything in Basic plus 16 additional data types. This allows for more in-depth analysis of market dynamics, competitor strategies, and web traffic flows.
Listing Management API: Local SEO on Autopilot
For businesses heavily focused on local SEO, the Listing Management API is a must. It’s designed for users of Semrush’s Local Premium Plan.
- This API lets you manage local business listings and synchronize location data, which is super helpful for businesses with multiple physical locations. The cool thing here is that requests to the Listing Management API don’t use up your standard API units. You just need the Semrush Local Advanced add-on.

Getting Your Hands Dirty: How to Get Started with the Semrush API
you’re convinced the Semrush API is a powerful tool. Now, how do you actually start using it? It’s a pretty straightforward process, but there are a couple of prerequisites you need to know about.
The Essential First Step: A Semrush Business Plan
Here’s the first crucial piece of information: the standard Semrush API is an add-on that’s only available if you have a Semrush Business plan. You can’t get API access with the Pro or Guru plans, or during a free trial.
The Business plan is designed for larger agencies and enterprises, costing around $499.95/month, or a bit less if you pay annually around $416.66/month. This plan offers much higher limits for projects, keyword tracking, and report results, along with features like white-label reports and API access. So, if you’re planning to dive into the API, make sure your Semrush subscription is at the Business level.
Securing Your Key: Where to Find Your Semrush API Key
Once you have a Business plan, you’ll need an API key. This key acts like a password, authenticating your requests and making sure only you can access your data.
You can usually find your Semrush API key in your account. Here’s the typical path: Ahrefs vs semrush 2024
- Log in to your Semrush account.
- Navigate to your Subscription info page.
- Look for a section related to “API Units” or “API Key.”
It’s super important to keep your API key confidential to maintain the security and integrity of your API usage. Treat it like your bank password!
Understanding Semrush API Units: The Currency of Data
Just having a Business plan and an API key isn’t quite enough for the Standard API. You also need to purchase API units separately. Think of these units as credits you use up with each API request. They’re not included in your monthly Business subscription fee.
- API Unit Pricing: The cost for API units is typically around $1 for every 20,000 credits. So, if you needed 10,000,000 units, that would cost you an additional $500 on top of your Business plan.
- How Units are Consumed: The number of units an API call consumes depends on the type of report you’re requesting and the amount of data it returns.
- Live vs. Historical Data Costs: This is a big one. Retrieving historical data almost always costs more units than requesting live data. For instance, if you’re pulling organic keyword data, one line of a report might cost 10 units for live results, but 50 units for historical data. This means if you want 1,000 organic keywords for 100 domains, it could cost 1,000,000 units for live data or 5,000,000 units for historical data.
- Checking Your Balance: You can check your current API units balance through your “Subscription Info” tab or by making a free API request specifically for your unit balance. It’s a good idea to calculate your expected API request limit before buying a package.
You can buy more API units via your Semrush subscription info page, or by contacting their sales team directly for larger needs.
Is Semrush API Free? The Scoop on Access and Trials
This is a common question, and the short answer is no, the standard Semrush API is not free. Connecting Zoho Books and HubSpot: Your Options
While Semrush does offer a free plan for its platform, it’s quite limited and primarily for basic SEO exploration. This free plan, and even the free trials for the Pro and Guru plans, do not include access to the Semrush API.
As we just discussed, to even access the Standard API, you need a paid Business subscription, and then you have to purchase API units separately. The only exception here is the Listing Management API, which doesn’t require separate API units, but still needs the Semrush Local Advanced add-on. The Trends API is generally included in paid subscriptions but might have different plans Basic/Premium depending on your needs.
So, if your goal is to use the API for programmatic data extraction and automation, be prepared for a paid investment in both a Business plan and API units.
Semrush API Documentation: Your Best Friend for Integration
Once you’re set up with a Business plan and API units, your next stop should be the official Semrush API documentation. I can’t stress this enough: it’s your go-to resource for everything related to making API calls. Connecting Zoho CRM and HubSpot: A Guide to Smarter Business Workflows
The documentation will give you all the details on:
- Available Endpoints: These are the specific URLs you’ll send your requests to, each corresponding to a different report or data type e.g., keyword overview, domain overview, backlink analytics.
- Request Parameters: For each endpoint, you’ll find a list of parameters you can use to refine your data request. This includes things like the domain name, keyword, database, display limits, and more.
- Response Formats: It explains how the data will be returned usually in JSON format, so you know how to parse and use it in your applications.
- Cost per Request: Crucially, the documentation will tell you how many API units each specific report or request consumes, helping you manage your budget.
- Rate Limits: Semrush sets limits on how many requests you can make per second often 10 inquiries per second from one IP address. The documentation will detail these limits to help you avoid errors.
Always keep a tab open with the Semrush API Documentation when you’re working on integrations. While it might not have comprehensive examples for every use case, it gives you the vital inputs you need for your code to work.
Putting It into Practice: Semrush API with Python
Many marketers and developers like to use Python for API integrations because it’s so readable and has a ton of useful libraries. Let’s walk through a simple example of how you might pull some data using the Semrush API with Python.
HubSpot Free vs. Zoho Free: Which One Wins for Your Business?
Setting Up Your Environment
First things first, you’ll need Python installed. If you don’t have it, a quick search for “install Python” will guide you.
Next, you’ll likely want to install a library to help you make HTTP requests. The requests library is a popular choice, or for a more direct Semrush approach, you might find community-built wrappers like semrush-cli useful.
You can install them using pip:
pip install requests
# Or for the specific CLI wrapper:
# pip install semrush-cli
A Simple Python Example: Pulling Domain Data
Let’s say you want to quickly grab an organic search report for a specific domain. You’ll need your API key and the domain you’re interested in.
import requests
import json
import os
# --- IMPORTANT: Replace 'YOUR_SEMRUSH_API_KEY' with your actual API key ---
# It's best practice to store your API key as an environment variable
# For this example, we'll put it directly, but for real projects, use:
# api_key = os.environ.get'SEMRUSH_API_KEY'
api_key = 'YOUR_SEMRUSH_API_KEY'
domain_to_analyze = 'example.com' # Replace with the domain you want to check
database = 'us' # For example, 'us' for United States, 'uk' for United Kingdom
# Base URL for the Semrush Analytics API check documentation for specific endpoints
# This example uses the organic_report endpoint
url = f"https://api.semrush.com/analytics/v1/organic_report?key={api_key}&domain={domain_to_analyze}&database={database}&display_limit=10"
printf"Making API request to: {url}"
try:
response = requests.geturl
response.raise_for_status # Raises HTTPError for bad responses 4xx or 5xx
# Semrush API often returns data in a CSV-like format by default for some reports,
# but for many analytical reports, it's JSON. Always check the specific report documentation.
# Let's assume for this example, it's a simple text response that might need parsing.
# If it's JSON, you'd use response.json
# For a CSV-like text response common for some reports:
data_text = response.text
print"\n--- Raw Data from API ---"
printdata_text
# To make it more structured, you'd typically parse this.
# For example, if it's CSV, you could use pandas:
# import pandas as pd
# from io import StringIO
# df = pd.read_csvStringIOdata_text, sep='.'
# print"\n--- Data as DataFrame ---"
# printdf.head
except requests.exceptions.HTTPError as errh:
printf"HTTP Error: {errh}"
except requests.exceptions.ConnectionError as errc:
printf"Error Connecting: {errc}"
except requests.exceptions.Timeout as errt:
printf"Timeout Error: {errt}"
except requests.exceptions.RequestException as err:
printf"Something unexpected happened: {err}"
# Example using semrush-cli if installed and configured
# from semrush.api import SemrushClient
# client = SemrushClientapi_key
# try:
# domain_overview = client.domain_ranksdomain_to_analyze
# print"\n--- Data from semrush-cli ---"
# printdomain_overview # This would typically be a JSON-like object
# except Exception as e:
# printf"Oops! Something went wrong with semrush-cli: {e}"
This simple script shows you how to construct an API request URL, send it, and print the raw response. Remember, you’ll need to adjust the URL and parameters based on the specific report you want and the exact format of your API key. Always refer to the official Semrush API documentation for the precise endpoints and parameters for each report type.
Key Benefits of Using the Semrush API for Your Business
Let's tie it all together and talk about how these technical capabilities translate into real-world advantages for your business. The Semrush API isn't just for developers. it’s a strategic asset for any business serious about digital growth.
# Automating Tedious Tasks
Imagine an intern spending days each month just downloading competitor keyword lists or checking backlink growth. With the API, those hours can turn into minutes. You can automate daily keyword monitoring, backlink monitoring, and competitor analysis. This means your team can shift their focus from repetitive data collection to more high-value, strategic thinking, like identifying new content opportunities or refining your link-building strategy.
# Custom Dashboards and Reporting
Generic reports only get you so far. The API lets you pull Semrush data and integrate it into your own business intelligence tools like Tableau, Microsoft Power BI, Google Sheets, or custom-built dashboards. This allows you to visualize data exactly how you need it, focusing on the metrics that are most critical to your organization's specific goals. For instance, you could combine organic traffic data from Semrush with conversion data from your CRM to get a holistic view of your marketing ROI.
# Deep Dive into Competitive Intelligence
The ability to programmatically access competitor data is powerful. You can integrate competitor profiles directly into your CRM to empower sales teams, or track and visualize competitor trends over time. Want to analyze keyword gaps among your top competitors or evaluate your performance against them? The API makes it possible to pull this data consistently and at scale, giving you a competitive edge.
# Scaling Your SEO Efforts
As your business grows, so does the volume of data you need to process. The Semrush API is built for scalability, allowing you to handle massive datasets and perform complex analyses that would be impossible manually. This is especially beneficial for agencies managing multiple client websites or large enterprises with extensive SEO needs. You can process millions of keywords or analyze thousands of domains without breaking a sweat, enabling your SEO strategy to grow with your business.
Is Semrush Reliable? Trusting Your Data
When you're making important business decisions based on data, reliability is key. So, how reliable is the data you get from the Semrush API?
Generally, Semrush is widely regarded as a highly reliable and accurate tool in the digital marketing industry. It's a comprehensive suite for competitive intelligence, keyword research, site audits, and more. The API provides extensive access to this data, which is consistently updated.
While no tool is 100% perfect all the time, Semrush's vast databases over 27 billion keywords, 808 million domains, and 43 trillion backlinks, with historical data since 2012 for some regions give it a strong foundation for accuracy. They gather data from a massive scale, and their algorithms are constantly refined.
However, like any data source, it's always good practice to cross-reference critical data points with other sources when possible and understand the specific metrics you're looking at. For example, search volume estimates are just that—estimates—and can vary slightly between tools. But for consistent, actionable insights across a broad range of SEO metrics, Semrush's data, accessed via its API, is a trustworthy foundation for your digital marketing strategies.
