How this service works
HTTP status, redirect chain with timings, total response time and security headers present or missing, for any public URL, measured from our server.
Output
Returns the final HTTP status code, the full redirect chain with per-hop timing data, the total end-to-end response time, and a breakdown of which HTTP security headers (e.g. HSTS, CSP, X-Frame-Options, X-Content-Type-Options) are present or absent for the given URL.
Example use cases
Security header audit for a new site
“Run a check on https://checkout.mystore.com and tell me which security headers like HSTS, CSP, or X-Frame-Options are missing — I want to know what I need to fix before launch.”
Redirect chain investigation
“Can you trace the full redirect chain for http://old.mybrand.com and tell me how many hops there are, where it ends up, and how long each step takes?”
External uptime spot-check
“Is https://api.partnercompany.io/health actually returning a 200 right now, and how fast is it responding from your servers?”
Technical details
Endpoint
GEThttps://api.cra-agent.tech/v1/paid/web/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an external, server-side measurement of a URL's HTTP status, redirect behavior, response time, or security header configuration — especially useful for auditing third-party sites, verifying redirects are set up correctly, or checking security posture without running the check from your own infrastructure.
Side effects
- Non-public or firewall-blocked URLs will fail to reach the target and return an error or timeout
- URLs on non-default ports may be rejected per the schema constraint
- Malformed or non-HTTP/HTTPS URLs will fail input validation
- Very slow URLs may time out before a response is recorded
- Internal/localhost URLs will not be reachable from the external server
