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)
Output
Returns a structured report covering: email syntax validity, whether the domain is a known disposable/burner provider, whether the address is a role account (e.g. admin@, noreply@), and live DNS lookup results including MX records (mail server presence), SPF record content, and DMARC policy — effectively assessing real-world deliverability.
Example use cases
Screening signups for fake emails
“Before we add this user to our database, can you verify whether signup@guerrillamail.com is a throwaway burner address and whether the domain has proper MX records set up?”
Pre-send deliverability check for campaigns
“I'm about to send a marketing email to contact@acmecorp.io — can you confirm it's syntactically valid, not a role account, and that the domain's MX and SPF records are correctly configured?”
Lead quality validation for sales pipeline
“We just got a new lead with the email ceo@somestartup.biz — can you run a full email verification on it to check if it's deliverable, check for DMARC, and flag it if it's a role or disposable address?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/email?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 record verification (MX, SPF, DMARC) in one response. Prefer it over simple regex or syntax-only validators when deliverability assurance and fraud/burner detection are required, especially in B2B lead enrichment, user registration flows, or pre-send campaign validation.
Side effects
- Missing or malformed email parameter returns a validation error
- DNS lookup timeout if the domain's nameservers are slow or unresponsive
- Domain does not exist (NXDOMAIN) resulting in no MX/SPF/DMARC data
- Payment not settled via x402 results in HTTP 402 response blocking the call
- Rate limiting if too many requests are made in a short window
