GET /api/x402/audit
unprobed
Full site quality audit across SEO (titles, descriptions, canonical, Open Graph, JSON-LD…), accessibility (alt text, form labels, heading order, landmarks…) and security headers (HSTS, CSP, XCTO…) — scored 0-100 per section with a copy-paste fix for every finding. $5 per audit. Fetch-based (served HTML; SPA shells noted). The agent-readiness scan is separate and free at /api/x402/deep-scan.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
