How this service works
Validates email syntax, disposable/burner provider status, role accounts, and live DNS MX/SPF/DMARC records. (Live x402 v2, IETF MPP & MCP endpoint at https://sec-intel.agentdiet.dev/v1/spf-dmarc-auditor)
Output
Returns a structured object indicating whether the email passed syntax validation, whether the domain is associated with a known disposable/burner provider, whether the address is a role account (e.g. admin@, info@), and the live DNS status of MX, SPF, and DMARC records for the domain.
Example use cases
Screening signups for fake emails
“Before I approve this new user registration, can you check if the email they gave me — free2use@guerrillamail.com — is from a disposable or burner provider and whether it actually has working MX records?”
Pre-send lead email validation
“I'm about to send an outreach campaign to leads@acmecorp.io — can you verify that this email address is syntactically valid, not a role account, and that the domain has proper SPF and DMARC records configured?”
Email security audit for a domain
“I want to audit the email security posture for the domain bigbank.com — can you pull up their MX, SPF, and DMARC DNS records and tell me if anything looks misconfigured or missing?”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/spf-dmarc-auditor?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a comprehensive, single-call check covering syntax, live DNS deliverability (MX), email authentication policy (SPF/DMARC), and disposable/role account risk — especially in fraud prevention, lead qualification, or security auditing contexts where a full-stack email health assessment is needed rather than just a ping or format check.
Side effects
- Missing or invalid 'email' parameter returns a validation error
- DNS lookup timeouts for unresponsive nameservers may result in inconclusive MX/SPF/DMARC results
- Newly registered domains with propagating DNS may show false negatives for MX/SPF/DMARC
- Disposable provider database may not include newly created throwaway services
- Payment required (HTTP 402) if x402 micropayment header is missing or insufficient
