X402 Data API
POST api.x402dataapi.com/v1/mail-security
Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
Paid x402 API for AI agents that checks MX records, SPF, DMARC, email security, phishing risk, domain mail configuration and anti-spoofing posture for a public domain.
