What you get

$0.05 website audit preflight for one public HTTPS URL. Runs seven deterministic HEAD-only website release checks for reachability, redirects, HSTS, CSP, nosniff and frame policy. Returns observed evidence, copy-paste fixes, an evidence ID and SHA-256 report integrity. Use it as the low-cost sampler before the same seller's $5 Site Quality Audit.
