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://cve-intel.agentdiet.dev/v1/spf-dmarc-auditor)
Output
Returns a structured object containing: email syntax validity, whether the provider is a known disposable/burner service, whether the address is a role account (e.g. info@, admin@), live MX record lookup results indicating deliverability, and DNS SPF and DMARC record presence and configuration status for the email's domain.
Example use cases
SaaS signup fraud screening
“Before I onboard this new user, can you verify that signup@tempmail.xyz is a real, deliverable email and not a disposable or burner account? Also tell me if DMARC and SPF are configured on that domain.”
B2B lead list email hygiene
“I've got a lead I want to reach out to — can you check whether ceo@startupco.com is actually deliverable, has working MX records, and isn't a role-based or throwaway address?”
Email infrastructure audit before cold outreach
“We're about to send a cold email campaign. Can you audit whether the recipient domain on james@bigcorp.net has SPF and DMARC records in place and confirm the address is reachable via live MX lookup?”

Endpoint
POSThttps://cve-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 covering syntax, disposable provider detection, role-account identification, and live DNS MX/SPF/DMARC auditing — especially in B2B lead enrichment, signup validation, or pre-send deliverability workflows. Prefer this over simple regex-only validators or domain-only checkers when live DNS verification and anti-spam record auditing matter.
Side effects
- Invalid or malformed email address causes a validation error response
- Domain has no MX records, indicating undeliverable address
- DNS lookup timeout or failure for SPF/DMARC records
- Unknown or newly registered domain with incomplete DNS propagation
- Payment failure via x402 if USDC balance is insufficient
