Output
A JSON object containing the HTTP response headers returned by the target URL, as key-value pairs (e.g. Content-Type, Server, Cache-Control, X-Frame-Options, Strict-Transport-Security, etc.).
Example use cases
Security header audit for a website
“Check the HTTP headers returned by https://mycompany.com — I want to know if they have Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security headers set.”
Detect server software from headers
“What server software is https://competitor.io running? Fetch its HTTP headers and look for the Server or X-Powered-By header.”
Debug caching headers for a CDN
“I need to check whether https://cdn.mybrand.com/assets/main.js is returning the right Cache-Control and ETag headers — can you look them up?”
Technical details
Endpoint
POSThttps://yruz.one/api/toolkit/http-headers-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly inspect the HTTP response headers of any public URL without writing custom networking code. It is ideal for security audits, debugging CDN or caching configurations, checking server software, and verifying CORS or HSTS policies on a per-URL basis.
Side effects
- Invalid or unreachable URL returns empty or error result
- Non-HTTP/HTTPS URLs are not supported
- Target server may block or timeout requests from the lookup service
- Redirects may return headers for the redirect response rather than the final destination
- Some servers return minimal or misleading headers
