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://x402broker.com/v1/disposable-email)
Output
Returns a structured report including: email syntax validity, whether the domain belongs to a known disposable/burner email provider, whether it is a role-based address (e.g. admin@, noreply@), and live DNS lookup results for MX, SPF, and DMARC records — giving an overall deliverability and trustworthiness assessment.
Example use cases
Block burner emails at signup
“We're getting a ton of fake signups using throwaway email addresses. Can you check if signup@guerrillamail.com is a disposable or burner email before I allow it to register?”
Email deliverability audit before campaign
“I'm about to send a newsletter campaign and I need to know if contact@acmecorp.io is actually deliverable — check its MX records and whether the domain has SPF and DMARC properly set up.”
Flag role accounts in lead database
“Before we add support@bigcompany.com to our CRM, can you verify whether it's a role-based address and confirm the domain has working mail exchange records?”
Technical details
Endpoint
GEThttps://x402broker.com/v1/disposable-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single API call to simultaneously check email syntax, disposable/burner status, role account detection, AND live DNS-based deliverability signals (MX/SPF/DMARC). It is ideal for fraud prevention at registration, lead qualification, or pre-send email list hygiene where both deliverability and authenticity matter.
Side effects
- Invalid or malformed email address input returns a syntax error
- Domain with no DNS records returns MX lookup failure
- Disposable provider lists may not include newly created burner domains
- DNS timeouts may cause incomplete MX/SPF/DMARC results
- Missing email query parameter returns a bad request error
