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-validator)
Output
Returns a structured object indicating: whether the email passes syntax validation, whether the domain has live MX records (deliverability), whether SPF and DMARC DNS records exist and are correctly configured, whether the provider is a known disposable/burner service, and whether the address is a role account (e.g. info@, admin@, noreply@).
Example use cases
Pre-send email list scrubbing
“Before I send my newsletter campaign, can you validate user@tempmail.com to make sure it's not a disposable burner address and that the domain actually has working MX records?”
CRM lead quality gate
“We just got a form submission from contact@noreply-domain.biz — can you check if that email is real, deliverable, and not a role account before I add it to our CRM?”
B2B outreach deliverability check
“I'm about to cold-email ceo@startupxyz.io — can you verify the syntax is correct, confirm the domain has MX records, and check whether SPF and DMARC are set up so my email won't bounce or land in spam?”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/email-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, real-time email validation that goes beyond simple regex — specifically when you need live DNS MX/SPF/DMARC lookups combined with disposable-provider and role-account detection in a single call. Prefer it over static list-based validators when deliverability accuracy matters (e.g. before CRM ingestion, outbound campaigns, or user registration flows).
Side effects
- DNS lookup timeout if the domain has slow or unresponsive nameservers
- False negatives on newly created disposable domains not yet in blocklists
- Invalid or malformed email input returns a syntax error
- Domain exists but has no MX records, flagged as undeliverable
- Payment failure via x402 if USDC balance is insufficient
