POST /tools/email-auth-dmarc-spf-check

blocked

Give it domains. For each it reads SPF, DMARC, DKIM and MX over keyless DNS-over-HTTPS and composes an anti-spoofing posture with specific findings and a signal (protected / mostly-protected / monitoring-only / spoofable / no-email-configured). Read-only DNS, agent-callable. One search per call (result caps in the input schema); failed lookups are not charged.

Verdict: not verified by an unpaid GET. 401/403/429: auth or bot protection. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
