SDK Examples

Ready-to-use code examples for integrating DevUtils API in your preferred programming language.

JavaScript / Node.js

Examples using native fetch API (Node.js 18+). For older versions, use node-fetch or axios.

Screenshot API

// Using fetch (Node.js 18+)
async function captureScreenshot(url) {
  const response = await fetch('https://api.devutils.io/v1/screenshot', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.DEVUTILS_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      url: url,
      fullPage: true,
      viewport: { width: 1920, height: 1080 }
    })
  });

  const data = await response.json();
  
  if (!data.success) {
    throw new Error(data.error.message);
  }
  
  return data.data.image_url;
}

// Usage
const imageUrl = await captureScreenshot('https://example.com');
console.log('Screenshot:', imageUrl);

HTML to PDF API

// Convert webpage to PDF
async function convertToPdf(url) {
  const response = await fetch('https://api.devutils.io/v1/pdf', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.DEVUTILS_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      url: url,
      pageSize: 'A4',
      orientation: 'portrait'
    })
  });

  const data = await response.json();
  
  if (!data.success) {
    throw new Error(data.error.message);
  }
  
  return data.data.pdf_url;
}

// Usage
const pdfUrl = await convertToPdf('https://example.com');
console.log('PDF:', pdfUrl);

Python

Examples using the requests library. Install with: pip install requests

Screenshot API

import os
import requests

def capture_screenshot(url: str) -> str:
    """Capture a screenshot of a webpage."""
    response = requests.post(
        'https://api.devutils.io/v1/screenshot',
        headers={
            'Authorization': f'Bearer {os.environ["DEVUTILS_API_KEY"]}',
            'Content-Type': 'application/json'
        },
        json={
            'url': url,
            'fullPage': True,
            'viewport': {'width': 1920, 'height': 1080}
        }
    )
    
    data = response.json()
    
    if not data['success']:
        raise Exception(data['error']['message'])
    
    return data['data']['image_url']

# Usage
image_url = capture_screenshot('https://example.com')
print(f'Screenshot: {image_url}')

HTML to PDF API

import os
import requests

def convert_to_pdf(url: str) -> str:
    """Convert a webpage to PDF."""
    response = requests.post(
        'https://api.devutils.io/v1/pdf',
        headers={
            'Authorization': f'Bearer {os.environ["DEVUTILS_API_KEY"]}',
            'Content-Type': 'application/json'
        },
        json={
            'url': url,
            'pageSize': 'A4',
            'orientation': 'portrait'
        }
    )
    
    data = response.json()
    
    if not data['success']:
        raise Exception(data['error']['message'])
    
    return data['data']['pdf_url']

# Usage
pdf_url = convert_to_pdf('https://example.com')
print(f'PDF: {pdf_url}')

cURL

Command-line examples for quick testing and debugging.

Screenshot API
