Site audit: Audit one public http or https page: Lighthouse scores, DNS, SPF, DMARC, DKIM selectors, TLS, security headers and subdomains. Verza calls a render worker and does not fetch the page itself. An empty body is a 402 when the worker can run. A private or loopback host is HTTP 400 after payment is verified and is not settled. A busy or unreachable worker is HTTP 503 with Retry-After and is not settled.
