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/disposable-email)
Output
Returns a structured object indicating whether the email passes syntax validation, whether the domain is a known disposable or burner provider, whether the address appears to be a role account (e.g. info@, admin@), and the live DNS status of MX, SPF, and DMARC records for the domain.
Example use cases
Fraud screening at user signup
“Before I create an account for this user, can you verify that their email address — signup123@guerrillamail.com — is not a disposable or burner provider and that it has valid MX records so I know it can actually receive mail?”
Sales lead email validation
“I have a lead with the contact email ceo@acmecorp.io — can you check if it's a real deliverable address, confirm the domain has proper MX and SPF records, and flag it if it looks like a role account?”
Pre-send deliverability audit
“Before I send our newsletter campaign, can you validate the email address newsletter-bounce@contoso.com and tell me whether the domain has DMARC configured and whether MX records are live?”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/disposable-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, real-time check of email syntax validity, disposable/burner provider detection, role-account flagging, and live DNS MX/SPF/DMARC verification in a single call. It is particularly useful for fraud prevention at signup, sales lead qualification, or pre-campaign deliverability auditing where you need DNS ground truth rather than just a static blocklist lookup.
Side effects
- Missing or malformed email field returns a validation error
- DNS lookup timeouts if the domain's nameservers are unresponsive
- Unknown or very new domains may return incomplete MX/SPF/DMARC data
- Disposable provider database may not include newly registered throwaway domains
- Network errors result in a 5xx response with no deliverability data
