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://shopify-intel.agentdiet.dev/v1/email-check)
Output
Returns a structured object indicating whether the email passes syntax checks, whether the domain has live MX records (confirming the domain can receive email), SPF and DMARC DNS record presence, whether the provider is a known disposable/burner service, and whether the address is a role-based account (e.g. admin@, noreply@).
Example use cases
Screening signups for fake emails
“Before we send the welcome email, can you verify that the new signup address throwaway123@mailnesia.com is legitimate — check if it's a disposable provider and whether the domain actually has MX records?”
B2B lead email validation before outreach
“I have a sales lead with the email sarah.jones@globalventures.io — can you confirm it's syntactically valid, not a role address, and that the domain has working MX, SPF, and DMARC records set up?”
Email security audit for a contact list
“Check support@techinnovators.com for me — I want to know if it's a role account and whether their domain has proper SPF and DMARC DNS records configured before we add them to our outreach list.”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/email-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, real-time single-email check that combines syntax validation, disposable/burner detection, role account flagging, and live DNS MX/SPF/DMARC lookup in one call. Prefer it over simple regex-only validators when deliverability and email security posture both matter, and over bulk list-cleaning services when checking individual addresses on-demand at low cost per call.
Side effects
- Missing or invalid email parameter returns a 400-level error
- DNS lookup timeouts may cause MX/SPF/DMARC checks to fail or return inconclusive results
- Unknown or newly created domains may not have indexed DNS records yet
- Payment not processed (HTTP 402) if x402 micropayment flow fails
- Email addresses with unusual but valid syntax may be incorrectly flagged by syntax parser
