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://agentdiet.dev/v1/email-check)
Output
Returns a structured report indicating whether the email passes syntax validation, whether the domain belongs to a known disposable or burner provider, whether the address is a role account (e.g. admin@, noreply@), and the live DNS lookup results for MX, SPF, and DMARC records including their values and presence/absence.
Example use cases
Signup form email gating
“Before we create an account for them, check if the email address newuser@mailinator.com is from a disposable provider, is a role account, and whether the domain has working MX records.”
Lead list hygiene audit
“I have a sales lead with the email contact@acmecorp.io — can you verify it's deliverable, not a throwaway, and that the domain has SPF and DMARC configured properly?”
Email security posture check
“Check whether the domain for support@startupxyz.co has MX records pointing somewhere real, and whether SPF and DMARC are set up correctly — I want to know if emails from there are likely to land in inboxes.”

Endpoint
GEThttps://agentdiet.dev/v1/email-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal email check combining syntax, disposable provider detection, role account flagging, and live DNS validation in a single call — especially useful for lead qualification, signup gating, or email list hygiene where you need more than just syntax checking.
Side effects
- Missing or malformed email parameter returns an error
- DNS timeout for domains with unresponsive nameservers may return partial results
- Unknown or very new disposable providers may not be flagged
- Private or internal domains may not have publicly resolvable DNS records
