How this service works
Inspect a public URL: HEAD redirect trace, DNS A/AAAA observations and security headers in one report. At most 4 targets, no page body. Includes timestamps, partial-result warnings and factual findings; no safety or reputation verdict.
Output
A structured report covering: the full HEAD redirect trace (each hop's status code and location), observed DNS A and AAAA records (IP addresses), detected HTTP security headers (e.g. HSTS, CSP, X-Frame-Options), timestamps for each observation, and any partial-result warnings if some checks could not complete. No page body is fetched. No safety or reputation verdict is included.
Example use cases
Redirect chain audit before link sharing
“Before I put this link in the newsletter, can you trace where https://bit.ly/3xY9zAB actually redirects to and show me every hop?”
Security header check for third-party site
“I'm about to embed a widget from https://widgets.vendor.com — can you tell me if it has security headers like Content-Security-Policy, X-Frame-Options, and HSTS set?”
DNS resolution check for a domain
“Can you look up what IP addresses https://api.partner-service.io resolves to and let me know if it returns both IPv4 and IPv6 addresses?”
Technical details
Endpoint
GEThttps://toolvend.dev/url/inspect?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, factual technical inspection of a public URL — specifically the redirect path, DNS IP resolution, and security header presence — without fetching page content. Prefer this over a full-page scraper when you only need infrastructure-level signals. Prefer it over a standalone DNS lookup when you want redirect tracing and HTTP headers bundled together. Not suitable for reputation scoring, malware detection, or page content analysis.
Side effects
- URL points to a private/internal destination — rejected with an error
- URL uses non-standard port — rejected
- URL contains credentials — rejected
- DNS resolution fails for the target domain — partial result with warning
- Target server does not respond to HEAD within timeout — partial result
- More than 4 target URLs submitted — rejected or truncated
- Malformed URL input — validation error
