Getting started

While Semrush is primarily a web-based platform with a GUI, its API allows for programmatic access to its data for custom applications or integrating into existing systems. The following example demonstrates a basic API call to retrieve keyword data using Python, assuming you have an API key and the requests library installed.

import requests
import json

API_KEY = "YOUR_SEMRUSH_API_KEY" # Replace with your actual API key
DOMAIN = "example.com"
DATABASE = "us"

def get_domain_organic_keywords(domain, api_key, database):
    url = f"https://api.semrush.com/analytics/v1/?type=domain_organic_keywords&key={api_key}&domain={domain}&database={database}&display_limit=10"
    try:
        response = requests.get(url)
        response.raise_for_status() # Raise an exception for HTTP errors
        
        # Semrush API can return data in various formats (CSV, JSON, XML). 
        # For JSON, ensure the 'display_columns' parameter is set to JSON output fields.
        # This example assumes a default text output that might need parsing.
        # For a structured JSON response, usually 'display_columns=json' or similar is needed.
        
        # Assuming the default output is CSV-like text, parsing it into a list of dicts
        lines = response.text.strip().split('\n')
        if len(lines) < 2: # Check if there's header and at least one data row
            return []

        headers = [h.strip() for h in lines[0].split(';')]
        keywords_data = []
        for line in lines[1:]:
            values = [v.strip() for v in line.split(';')]
            if len(values) == len(headers):
                keywords_data.append(dict(zip(headers, values)))
        
        return keywords_data

    except requests.exceptions.HTTPError as http_err:
        print(f"HTTP error occurred: {http_err}")
    except Exception as err:
        print(f"Other error occurred: {err}")
    return None

if __name__ == "__main__":
    organic_keywords = get_domain_organic_keywords(DOMAIN, API_KEY, DATABASE)
    if organic_keywords:
        print(f"Top 10 organic keywords for {DOMAIN} in {DATABASE.upper()} database:")
        for i, keyword in enumerate(organic_keywords):
            print(f"  {i+1}. Keyword: {keyword.get('Keyword')}, Position: {keyword.get('Position')}, Volume: {keyword.get('Search Volume')}")
    else:
        print("Could not retrieve organic keywords.")

This Python snippet illustrates how to query the Semrush API for a domain's organic keywords. You would replace "YOUR_SEMRUSH_API_KEY" with your actual API key obtained from your Semrush account. The DOMAIN and DATABASE parameters specify the target website and the regional search database to query, respectively. The output is a list of dictionaries, each representing a keyword with its associated metrics like position and search volume. Always consult the official Semrush API documentation for the most current endpoints, parameters, and response formats.
