How this service works
Fetch a URL and grade its HTTP security headers: CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and COOP/CORP. Returns a 0–100 score, a letter grade, and a concrete recommendation for every missing header. Use this when an agent needs to grade a site's HTTP security headers + fix hints.
Output
Returns a numeric score from 0 to 100, a letter grade (e.g. A, B, C, D, F), and for each of the key HTTP security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, CORP) — whether it is present, its current value if set, and a concrete remediation recommendation if it is missing or misconfigured.
Example use cases
Pre-launch security header audit
“We're about to launch our new SaaS product at app.launchpad.io — can you scan its HTTP security headers, give it a grade, and tell us what we need to fix before we go live?”
Competitor security posture check
“I want to know how well our competitor's site stripe.com does on HTTP security headers — what's their score and letter grade, and are they missing anything important like CSP or HSTS?”
Recurring compliance header check
“Can you audit the security headers on https://portal.healthapp.com and list every missing header with a concrete recommendation so our DevOps team knows what to add?”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/security/security-headers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured, scored audit of a specific website's HTTP security headers with actionable fix recommendations — especially useful in DevSecOps pipelines, pre-launch checklists, compliance audits, or when evaluating third-party sites. Prefer this over a generic HTTP request when you want graded analysis rather than raw header values.
Side effects
- Invalid or unreachable URL returns an error response
- Private/internal IP addresses blocked by SSRF guard
- Malformed URL input causes validation failure
- Target site returns non-HTTP response (e.g. DNS failure)
- Rate limit exceeded for the API key
