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://sec-intel.agentdiet.dev/v1/disposable-email)
Output
Returns a structured object indicating whether the email passes syntax validation, whether the domain is associated with a disposable or burner provider, whether it is a role-based account (e.g. admin@, info@), and the live DNS status of MX, SPF, and DMARC records for the domain — giving a comprehensive deliverability and risk assessment.
Example use cases
Signup fraud screening for SaaS product
“Before I create an account for someone who just signed up with the email user@guerrillamail.com, can you check whether it's a disposable burner address and whether the domain has valid MX records?”
Lead quality check before CRM import
“I've got a new lead with the email sales-contact@bizpro.io — can you verify it's a real deliverable address with proper DNS mail records before I add it to our CRM?”
Email list hygiene before campaign send
“Before we send out our newsletter, check whether newsletter@noreply-updates.net is a valid, non-role-account email with working MX and DMARC records so we don't waste sends or hurt our sender reputation.”

Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/disposable-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a multi-signal email check combining syntax validation, real-time DNS lookups (MX, SPF, DMARC), disposable provider detection, and role account flagging in a single call — particularly useful for agent workflows requiring fraud screening at signup, lead qualification, or pre-send list hygiene. Prefer it over simple regex validators when live DNS verification and burner-email detection are both required.
Side effects
- Missing or malformed email parameter returns a validation error
- DNS timeout or unreachable nameserver may result in incomplete MX/SPF/DMARC data
- Newly registered disposable domains not yet in blocklists may not be flagged
- Very long or unusual TLDs may produce unexpected syntax results
- Rate limiting or payment failure (402) if quota exceeded without valid x402 payment
