How this service works
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.
Output
A JSON object containing the queried domain name, an array of MX records, and boolean presence indicators for SPF and DMARC records (e.g. {"domain": "example.com", "mx": [...], "spf": {"present": true}, "dmarc": {"present": true}}).
Example use cases
Example prompt
“Can you check the email security setup for stripe.com — specifically whether it has SPF and DMARC records configured, and what MX records are in use?”
Technical details
Endpoint
POSThttps://api.x402dataapi.com/v1/mail-securityWhen to prefer
Use this endpoint when you need a quick, pay-per-request DNS-level mail security audit for a single domain — specifically to check MX, SPF, and DMARC presence — without setting up a subscription-based service or running your own DNS queries. Ideal for AI agents needing on-demand email security intelligence at low cost ($0.001 USDC per call).
Side effects
- Invalid or non-existent domain returns empty or error response
- Domain with no DNS records may return empty mx array and false for SPF/DMARC
- Network timeout if DNS resolution is slow
- Malformed domain string may cause 4xx validation error
- Payment failure via x402 protocol blocks the request
