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/email-validator)
Output
Returns a structured object indicating email syntax validity, whether the domain uses a known disposable/burner provider, whether the address is a role account (e.g. info@, admin@), and live DNS lookup results for MX, SPF, and DMARC records — giving a full deliverability and risk profile for the address.
Example use cases
Pre-send lead list scrubbing
“Before we send this marketing campaign, check if contact@newsletter-deals.io is a real deliverable address or a disposable burner — and whether its domain has proper MX and DMARC records set up.”
Signup fraud detection
“A new user just registered with temp-mail123@guerrillamail.com — can you verify whether that's a disposable or throwaway email address I should flag before approving their account?”
B2B domain mail hygiene audit
“I'm about to cold-email noreply@bigcorp.com — can you tell me if that's a role account, whether the domain has working MX records, and if SPF and DMARC are properly configured?”

Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/email-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive single-call email check that combines syntax validation, disposable provider detection, role account identification, and live DNS MX/SPF/DMARC record verification — especially useful for lead qualification, fraud prevention, or email list hygiene in agentic workflows that support HTTP 402 micropayments.
Side effects
- Missing or malformed email parameter returns a 400 validation error
- DNS lookup timeouts for unresponsive domains may yield partial results
- Unknown or newly registered disposable providers may not be flagged
- Payment not completed (HTTP 402) blocks the response
- Domains with intentionally hidden DNS records may return incomplete MX/SPF/DMARC data
