Why CORSPROXY

vs. Traditional Web Scraping

Traditional approach

  • Set up Puppeteer or Playwright
  • Manage headless Chrome instances
  • Build & maintain proxy rotation
  • Handle CAPTCHAs manually
  • Parse raw HTML with custom selectors
  • Pay for separate scraping infrastructure

With CORSPROXY

  • One URL prefix — no setup required
  • Structured JSON output, ready to use
  • Custom request headers per call
  • Runs from the browser or server
  • No proxy rotation needed
  • Included in your CORSPROXY plan

Structured Extraction JSON output
// Extract structured data from any page
const url =
  'https://corsproxy.io/' +
  '?key=YOUR_API_KEY' +
  '&extract=1' +
  '&format=json' +
  '&url=' + encodeURIComponent('https://play.google.com/store/apps/details?id=com.example.app');

const res = await fetch(url);
const data = await res.json();
console.log(data.title, data.description, data.rating);
Custom Headers Bypass bot detection
// Add custom headers to bypass bot detection
const params = new URLSearchParams({
  key: 'YOUR_API_KEY',
  extract: '1',
  format: 'json',
  reqHeaders: 'accept-language:en-US,en;q=0.9',
  url: 'https://www.amazon.com/dp/B0EXAMPLE',
});

const res = await fetch(`https://corsproxy.io/?${params}`);
const data = await res.json();
Raw HTML + Parse DOMParser in browser
// Fetch raw HTML from any URL
// Useful for custom parsing in your own code
const url =
  'https://corsproxy.io/' +
  '?key=YOUR_API_KEY' +
  '&url=' + encodeURIComponent('https://news.ycombinator.com/');

const res = await fetch(url);
const html = await res.text();

// Parse with DOMParser in the browser
const parser = new DOMParser();
const doc = parser.parseFromString(html, 'text/html');
const titles = [...doc.querySelectorAll('.titleline a')]
  .map(a => a.textContent);

Responsible Use

Only scrape sites you have permission to access. Respect robots.txt, terms of service, and applicable law. CORSPROXY is intended for legitimate data collection — not for bypassing access controls or scraping personal data without consent.

Production plan

Start scraping in minutes.

No Puppeteer. No proxy pools. No infra. Just your API key and a URL.
