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-spy.agentdiet.dev/v1/disposable-email)
Output
Returns a structured object indicating whether the email passed syntax validation, whether the domain is a known disposable/burner provider, whether the address is a role account (e.g. info@, noreply@), and the live DNS status of MX, SPF, and DMARC records for the email's domain.
Example use cases
Screen sign-up emails for fake accounts
“Someone just signed up with the email free99@guerrillamail.com — can you check if it's a disposable burner address or a real deliverable inbox before I let them through?”
Validate B2B lead email before outreach
“I have a prospect email, ceo@acmecorp.io — can you verify it's syntactically valid, not a role account, and that the domain has live MX and SPF records so I know it's worth reaching out to?”
Pre-send email list quality audit
“Before I blast this campaign, check support@newsletter-example.com for me — is it a role account, does the domain have DMARC set up, and will the email actually be deliverable?”

Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/disposable-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 flagging, and live DNS MX/SPF/DMARC verification — especially useful before onboarding users, enriching B2B leads, or filtering email lists to remove junk or undeliverable addresses.
Side effects
- Missing or empty email parameter returns a validation error
- Malformed email string may return syntax-invalid without DNS lookup
- Temporary DNS timeouts may cause MX/SPF/DMARC checks to fail or return inconclusive
- Unknown or very new domains may not have MX/SPF/DMARC records and return absent status
- Payment not provided or insufficient results in HTTP 402 response
