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-verify)
Output
Returns a structured object indicating: whether the email passes syntax checks, whether the domain belongs to a known disposable/burner provider, whether it is a role-based address (e.g. admin@, info@), and the live DNS lookup results for MX, SPF, and DMARC records, collectively indicating whether the address is safe to email and likely to be delivered.
Example use cases
Lead list email hygiene scrub
“Before we import this lead list, can you verify whether contact@acmecorp.io is actually deliverable — check if it's a real inbox, not a role address or throwaway, and confirm the domain has proper MX and DMARC records set up?”
Signup fraud detection filter
“A new user just registered with the email noreply@guerrillamail.com — can you tell me if that's a disposable or burner email and whether it's a role account we should block from signing up?”
Cold outreach domain warm-up check
“I'm about to send cold emails to a list of prospects — can you verify that sarah.jones@prospectco.com has live MX records and the domain has SPF and DMARC configured so my emails won't bounce or get flagged?”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/email-verify?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 lookups — rather than separate tools for each layer. Particularly valuable for lead enrichment pipelines, signup fraud prevention, and pre-send deliverability screening where a false positive (emailing an invalid or risky address) has meaningful cost.
Side effects
- Invalid or missing email field returns a validation error
- DNS lookup timeout for obscure or newly registered domains may result in inconclusive MX/SPF/DMARC results
- Newly created disposable providers not yet in blocklists may pass the burner check
- Private/internal domains with no public MX records will appear undeliverable even if valid
- Rate limiting or payment failure (402) if x402 USDC balance is insufficient
