  • check_url_headersFetch and grade a URL's security headersread-only

    Send a HEAD request (GET when the server answers 405 or 501, or when method is GET) to a public http or https URL, follow up to max_redirects redirects (default 5) and grade the final response's security headers. Returns the final URL, status, redirect chain, every response header, and per-header pass/warn/fail/info checks with explanations, recommendations and an overall grade from A+ to F. Refuses URLs whose host is localhost, a .local or .internal name, or resolves to a private, loopback, link-local or cloud-metadata address. The response body is never downloaded.

  • explain_headerExplain a security headerread-only

    Describe what one response header does, the recommended value and a reference link. Headers: content-security-policy, strict-transport-security, x-frame-options, x-content-type-options, referrer-policy, permissions-policy, cross-origin-opener-policy, cross-origin-resource-policy, x-xss-protection, server, x-powered-by, set-cookie.

  • grade_headersGrade a supplied header setread-only

    Grade response headers you already have, without any network access. Pass headers as an object of name to value (names are case-insensitive; Set-Cookie may be an array). Returns the same per-header checks and overall grade as check_url_headers. Set https to false when the response came over plain HTTP.
