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://hn-pulse.agentdiet.dev/v1/email-validator)
Output
Returns a structured object indicating whether the email passed syntax validation, whether the provider is a known disposable/burner service, 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's domain — giving a comprehensive deliverability and legitimacy assessment.
Example use cases
Lead quality check before CRM import
“Before I import this lead list, can you verify that sarah.jones@acmecorp.io is a legitimate, deliverable email — not a throwaway address — and that its domain has proper MX and DMARC records set up?”
Disposable email detection at signup
“A new user just signed up with temp-mail123@guerrillamail.com — can you tell me if that's a burner or disposable email provider so I can decide whether to block the registration?”
Email infrastructure audit for outreach
“I'm about to send a cold outreach campaign to marketing@startupxyz.co — can you verify the syntax is valid, check whether it's a role account, and confirm the domain has working MX and SPF records so my emails won't bounce?”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/email-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, all-in-one email validation that goes beyond simple syntax checking — combining disposable/burner detection, role account flagging, and live DNS MX/SPF/DMARC verification in a single call. Ideal for pre-import lead validation, signup fraud prevention, and outreach deliverability checks where multiple signal types are needed simultaneously.
Side effects
- Invalid or missing email parameter returns a validation error
- DNS lookup timeouts may occur for newly registered or slow-responding domains
- Disposable provider list may not cover every burner domain
- Role account detection may produce false positives for legitimate addresses
- Domains with no public DNS records may return incomplete MX/SPF/DMARC results
