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://llms-generator.agentdiet.dev/v1/email)
Output
Returns a structured JSON object indicating email syntax validity, whether the domain belongs to a known disposable/burner provider, whether the address is a role account (e.g. info@, support@), and the live DNS lookup results for MX, SPF, and DMARC records — giving a complete deliverability and trust profile for the address.
Example use cases
Pre-send email list hygiene
“Before I send my newsletter campaign, run a check on subscriber@newsletters.io to confirm it's a real deliverable address, not disposable, and that the domain has proper MX and DMARC records set up.”
Signup fraud prevention
“A new user just registered with the email temp123@mailinator.com — can you verify whether that's a disposable or burner email address so I can decide whether to block the signup?”
B2B lead enrichment validation
“I scraped a lead with contact email info@acmecorp.com — check if it's a role account, whether the domain has live MX records, and if DMARC and SPF are configured, so I know if it's worth reaching out.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, comprehensive email validation covering syntax, live DNS deliverability (MX), authentication records (SPF/DMARC), and disposable/role-account risk signals — particularly in agent workflows where x402 micropayment billing per call is acceptable and you need structured machine-readable output suitable for downstream decision-making.
Side effects
- Missing required 'email' parameter returns a 400 or validation error
- Malformed email string may return syntax-invalid result with no DNS lookup performed
- DNS lookup timeout or unreachable nameserver may result in partial or null MX/SPF/DMARC data
- Payment not provided returns HTTP 402 requiring x402 USDC payment
- Very new or obscure domains may have incomplete disposable provider classification
