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://github-audit.agentdiet.dev/v1/disposable-email)
Output
Returns a structured object indicating: whether the email address has valid syntax, whether the domain is a known disposable/burner provider, whether the address is a role account (e.g. admin@, support@), and the live DNS status of MX, SPF, and DMARC records for the email domain — giving an overall deliverability and risk assessment.
Example use cases
Block burner emails at signup
“Before creating this account, check whether the email signup@guerrillamail.com is a disposable or burner address and whether its domain has legit MX records — I want to block throwaway signups.”
Validate leads before outreach
“I have a sales lead with email cfo@acmecorp.io — can you confirm it passes syntax validation, isn't a role account, and that acmecorp.io has proper MX and SPF records so my outreach will actually land?”
Audit domain email security posture
“Check the email admin@startupxyz.com and tell me whether that domain has SPF and DMARC records configured correctly, so I can assess their email security posture.”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/disposable-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call email health check that combines syntax validation, disposable provider detection, role-account flagging, and live DNS MX/SPF/DMARC verification. Prefer it over basic syntax-only validators when deliverability and fraud risk matter, and over domain-only DNS tools when you need the full email-level picture in one request.
Side effects
- Missing or malformed email parameter returns a 400 validation error
- DNS lookup timeouts for uncommon or slow-responding domains may cause incomplete MX/SPF/DMARC results
- Very new or obscure domains may not have SPF/DMARC records, returning absent rather than invalid
- Payment required (HTTP 402) if x402 credentials are not provided or balance is insufficient
- False negatives possible for disposable providers not yet in the blocklist database
