HTTP Headers Checker

Inspect HTTP response headers, security headers, redirect chain and TLS info for any URL. Free online HTTP headers checker with API access.

This tool fetches the URL from our server. Only the URL you enter is sent — no data is stored.

API Usage (cURL)

curl -X POST https://wivrix.com/api/headers \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "method": "HEAD", "follow_redirects": true}'

How to Use the HTTP Headers Checker

  1. Enter a full URL (e.g. https://example.com).
  2. Choose HEAD (faster) or GET (follows redirects more reliably).
  3. Click Check Headers to inspect the response.

Security Headers Explained

  • Strict-Transport-Security — forces HTTPS for all future requests
  • Content-Security-Policy — prevents XSS and injection by whitelisting allowed sources
  • X-Content-Type-Options — prevents MIME-type sniffing
  • X-Frame-Options — prevents clickjacking by disabling iframe embedding
  • Referrer-Policy — controls how much referrer info is sent with links
  • Permissions-Policy — controls which browser features (camera, mic, etc.) can be used

API Integration

Send a POST request to /api/headers with url, optional method (HEAD/GET), and follow_redirects. The response includes all headers, redirect chain, TLS info, security header analysis with a score, and timing data. Rate limited to 30 requests per minute.

Privacy: Only the URL you enter is sent to the server. No data is stored.
