How this service works
HTTP security header audit for any URL - HSTS, CSP, clickjacking, referrer policy, cookies and a letter grade
Output
A JSON object containing the final audited URL, a letter grade (A–F), a numeric score (0–100), a boolean HTTPS flag, a summary of passing/warning/failing check counts, and an array of per-header findings — each with the header name, observed detail, pass/warn/fail/info status, and a recommended fix value where applicable. Also includes redirect count, HTTP status code, and timestamp.
Example use cases
Pre-launch security compliance check
“Before we go live, can you audit the security headers on https://myapp.company.com and tell me the letter grade, score, and anything we need to fix — especially HSTS and CSP?”
Third-party vendor security vetting
“I need to verify the HTTP security posture of a vendor site before we integrate with them — can you audit https://vendor-portal.example.com and flag any failing headers or cookie issues?”
Continuous monitoring of a competitor
“Can you check what security header grade https://competitorsite.com is getting right now, including whether they have clickjacking protection and a referrer policy in place?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/audit/headers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured HTTP security header assessment of a public URL with machine-readable per-header findings and an actionable letter grade. It is ideal for automated security compliance checks, pre-launch audits, or continuous monitoring workflows. Prefer it over generic web scanners when you specifically need header-level detail (HSTS, CSP, clickjacking, referrer policy, cookie flags) returned as structured JSON rather than an HTML report.
Side effects
- Private, loopback, or link-local IP addresses are refused
- Malformed or non-HTTP/HTTPS URLs are rejected by pattern validation
- Unreachable or offline URLs may return an error or incomplete findings
- Rate-limit or network timeouts on slow external servers
- Redirect chains that exceed a limit may be truncated
