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://cve-intel.agentdiet.dev/v1/email)
Output
Returns a structured object indicating whether the email has valid syntax, whether the domain has live MX records, the presence and validity of SPF and DMARC DNS records, whether the address belongs to a known disposable or burner email provider, and whether it appears to be a role-based account (e.g. info@, admin@).
Example use cases
Block disposable emails at signup
“Before I let this user register with the email temp.user123@mailnull.com, can you check if it's a throwaway or burner address, and whether it has live MX records that can actually receive mail?”
Email security audit before outreach
“I'm about to send a cold email campaign to prospects@acmecorp.io — can you verify that this address has valid MX records and that the domain has SPF and DMARC configured so my emails won't bounce or get flagged?”
Detect role account before CRM import
“We're importing a batch of leads and one of them has the address info@bigclient.com — can you tell me if this is a role account, if the domain's MX is live, and whether it's likely to be deliverable?”

Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call email verification that combines syntax checking, live DNS MX/SPF/DMARC lookups, disposable provider detection, and role account flagging — especially in agent workflows requiring fraud prevention, lead qualification, or deliverability assurance before sending email communications. Prefer this over simple regex-only validators when real-time DNS confirmation is required.
Side effects
- Invalid or malformed email address returns a syntax error
- Domain does not exist or has no DNS records, resulting in MX lookup failure
- Disposable provider list may not cover newly created burner services
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- DNS lookup timeouts for slow or unreachable nameservers
