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 address passes syntax validation, whether the provider is a known disposable/burner service, whether it is a role account (e.g. info@, admin@), and the live DNS lookup results for MX records (deliverability), SPF record presence and validity, and DMARC policy configuration.
Example use cases
Signup fraud screening for SaaS
“Before I create an account for the user who just signed up with temp-mail@guerrillamail.com, check if that email is from a burner or disposable provider and whether it's a role address.”
Pre-send deliverability audit
“I'm about to send an outreach email to cto@acmecorp.io — can you confirm the domain has working MX records and that SPF and DMARC are properly configured so my message won't bounce or get flagged as spam?”
Email security posture check
“I want to know if the domain fintech-startup.com has its email security properly locked down — check if they have valid SPF and DMARC DNS records in place.”

Endpoint
POSThttps://sec-intel.agentdiet.dev/v1/spf-dmarc-auditor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call email health check that combines syntax validation, live DNS MX/SPF/DMARC verification, and disposable/role-account detection — especially in agentic workflows that require micropayment-native (x402) access without managing separate DNS lookup, blocklist, or DMARC-checker services.
Side effects
- Invalid or malformed email string returns a syntax error flag
- Domain does not exist or has no DNS records, resulting in MX lookup failure
- Rate limiting or payment failure (HTTP 402) if micropayment is not attached
- Transient DNS resolution timeouts causing incomplete record results
- Disposable provider list may lag behind newly created throwaway services
