Prerequisites

1. API Key

First, you'll need a ScrapeCreators API key to authenticate your requests.

Sign up at app.scrapecreators.com to get your free API key with 100 requests.

2. Development Environment

Make sure you have the following installed:

  • • JavaScript and its dependencies
  • • A code editor (VS Code, Sublime, etc.)
  • • Basic understanding of API requests
  • • Command line interface access

Step 1: Install HTTP Client

Axios is a promise-based HTTP client for Node.js

npm
npm install axios

Step 2: API Implementation

Now let's make a request to the Google Ad Library API using JavaScript. Replace YOUR_API_KEY with your actual API key.

JavaScript
import axios from 'axios';

const API_KEY = 'YOUR_API_KEY';

async function scrape() {
  try {
    const response = await axios.get(`https://api.scrapecreators.com/v1/google/adLibrary/advertisers/search?query=lululemon&region=AU`, {
      headers: {
        'x-api-key': API_KEY,
        'Content-Type': 'application/json'
      }
    });

    console.log('Response:', response.data);
    return response.data;
  } catch (error) {
    console.error('Error:', error.response?.data || error.message);
  }
}

// Usage
scrape();

Step 3: Testing Your Code

API Parameters

This endpoint accepts the following parameters:

queryRequired(string)

The query to search for

Example: lululemon

regionOptional(string)

2-letter country code to search in. Defaults to US when omitted.

Example: AU

Run Your Code

Execute your script to test the API connection. You should see a JSON response with Google Ad Library search results data.

✅ Success: You should receive a structured JSON response containing the requested data.

Expected Response

Here's an example of the JSON response you'll receive:

Best Practices

1

Error Handling

Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.

2

Caching

Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.

3

Security

Never expose your API key in client-side code. Use environment variables and secure key management practices.

Performance Tips

Batch Requests

When scraping multiple search results, consider batching requests to maximize throughput while staying within rate limits.

Async Processing

Use asynchronous processing in JavaScript to handle multiple requests concurrently and improve overall performance.
