How this service works
HTTP security headers check for a website: HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, plus server and content-type headers, status and final URL. Web security audit, compliance checks and hardening reports. $0.01 per URL.
Output
A JSON object containing the presence and values of key HTTP security headers (HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy), plus the server and content-type response headers, the HTTP status code, and the final resolved URL after any redirects.
Example use cases
Pre-launch security header audit
“Before we go live, can you audit the security headers on https://staging.myapp.com and tell me which ones like HSTS, CSP, and X-Frame-Options are missing or misconfigured?”
Compliance check for client website
“I need to verify that https://www.clientsite.com has all the required security headers for our compliance report — check for HSTS, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.”
Monitoring competitor security posture
“Can you look up what HTTP security headers https://www.competitor.com has configured, including their server header and final URL after any redirects?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/http-headersWhen to prefer
Choose this endpoint when you need a quick, structured snapshot of a website's HTTP security header configuration for auditing, compliance reporting, or hardening recommendations. It is purpose-built for security header analysis and returns all the major headers in one call, unlike a general URL status checker or a full vulnerability scanner.
Side effects
- URL is unreachable or times out — endpoint may return an error or empty headers
- Invalid URL format provided — request may fail validation
- Website blocks automated requests — headers may be incomplete or absent
- Non-HTTP/HTTPS schemes not supported
- Target server uses non-standard header casing — some headers may not be detected
