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://agentdiet.dev/v1/disposable-email)
Output
Returns a structured JSON response indicating email syntax validity, whether the domain belongs to a known disposable/burner email provider, whether the address is a role account (e.g. admin@, noreply@), and live DNS lookup results including MX records presence, SPF record content, and DMARC policy record.
Example use cases
Signup fraud prevention for SaaS
“Before I activate this new user account, check if the email they signed up with — free2use@guerrillamail.com — is a disposable or burner address and whether it has working mail server records.”
Email list hygiene before campaign send
“I'm about to send a marketing email to newsletter@contoso.biz — can you verify it's not a role account, confirm the domain has valid MX records, and check if SPF and DMARC are properly set up?”
Lead qualification in B2B pipeline
“We got a demo request from info@startupxyz.io — is that a role account? Does the domain actually have MX records and email authentication configured so I know it's a real business?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/disposable-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, combined email validation that covers syntax, disposable/burner detection, role account identification, and live DNS MX/SPF/DMARC checks in a single call — particularly for agent workflows doing signup fraud prevention, lead qualification, or pre-send deliverability checks. Prefer over manual DNS lookups or separate disposable-email lists when you need all signals in one low-cost API call.
Side effects
- Invalid or malformed email address provided — returns syntax error
- Domain has no MX records — flagged as undeliverable
- DNS lookup timeout for MX/SPF/DMARC — partial results returned
- Unknown disposable provider not in blocklist — may produce false negative
- Missing email query parameter — returns 400 bad request
