How this service works
Fetch a URL with browser-like headers and return final URL, HTTP status and all response headers.
Output
Returns the final URL after any redirects, the HTTP status code, and a complete map of all response headers returned by the server — all fetched using browser-like request headers to avoid bot-blocking.
Example use cases
Detect redirect destination of a URL
“I need to know where https://bit.ly/3xKjP2q actually redirects to — can you fetch it with browser headers and tell me the final URL and status code?”
Check if a page is behind a CDN
“Can you fetch https://shop.acme.com and show me all the response headers so I can see if it's being served through Cloudflare or another CDN?”
Verify a URL is live before linking
“Before I publish this blog post, can you check that https://docs.myproduct.com/setup returns a 200 status and show me its response headers?”
Technical details
Endpoint
GEThttps://164.160.90.241.sslip.io/api/web-browser-header-fetch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect HTTP response headers, detect redirects, or verify a URL's reachability without downloading its full body. It's ideal for infrastructure checks, redirect tracing, CDN detection, and header auditing. It differs from a full web scraper in that it returns headers only (not page content), making it faster and lighter for pure HTTP-level inspection.
Side effects
- URL is unreachable or times out — returns an error with no status
- URL returns a non-standard status (e.g. 5xx) — returned as-is
- URL requires authentication or is behind a login wall — headers from the redirect/auth page are returned instead
- Invalid or malformed URL — likely returns a validation error
- Server returns no headers or minimal headers — empty header map
