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://github-audit.agentdiet.dev/v1/email-check)
Output
Returns a structured object indicating whether the email passed syntax validation, whether the domain is from a known disposable/burner provider, whether it is a role account (e.g. admin@, info@), and live DNS lookup results for MX, SPF, and DMARC records — giving a composite deliverability assessment.
Example use cases
Screening signups for burner emails
“Before I add this new user signup to my CRM, can you verify that noreply@mailinator.com isn't a disposable or fake email address and that the domain actually has working MX records?”
Lead list email hygiene
“I have a lead with the email contact@startupxyz.io — can you check if it's a real deliverable address, whether it's a role account, and if the domain has SPF and DMARC set up properly?”
Email infrastructure audit before outreach
“We're about to send a cold outreach campaign to prospects@bigcorp.com — can you verify the domain's MX, SPF, and DMARC DNS records are all properly configured so our emails won't bounce or get flagged?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/email-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive single-call email check that covers syntax, disposable provider detection, role account flagging, and live DNS MX/SPF/DMARC verification together — especially in B2A or agent-driven workflows where micropayment via x402 is already supported and you need actionable deliverability signals before sending outreach or onboarding a user.
Side effects
- Missing or malformed email parameter returns a validation error
- DNS lookup timeouts for domains with slow or unreachable nameservers
- False negatives for newly created disposable domains not yet in blocklists
- Domains with no MX records flagged as undeliverable even if they accept mail via other means
- Rate limiting or HTTP 402 payment required if micropayment not fulfilled
