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)
Output
Returns a structured object indicating whether the email address is syntactically valid, whether the domain has live MX records enabling mail delivery, SPF and DMARC DNS record presence and policy details, whether the provider is a known disposable or burner service, and whether the address appears to be a role account (e.g. admin@, noreply@).
Example use cases
Screening leads before CRM import
“Before I import these leads into our CRM, check whether contact@acmecorp.io is a real deliverable email — flag it if it's a role account, disposable domain, or missing MX records.”
Detecting fake signups at registration
“A new user just signed up with user123@guerrillamail.com — can you verify if that's a burner or disposable email address and whether it would actually receive mail?”
Email domain health audit for outreach
“I'm about to send a cold outreach campaign to sales@bigclient.com — can you confirm the domain has valid MX records, an SPF policy, and DMARC configured so my messages won't bounce or get flagged?”

Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, real-time email hygiene check that goes beyond simple syntax validation — specifically when you need live DNS MX resolution combined with SPF/DMARC policy checks and disposable-provider detection in a single call. It is well-suited for lead qualification pipelines, user registration fraud prevention, and email outreach pre-screening where deliverability and domain reputation all matter.
Side effects
- Invalid or malformed email input returns a syntax error response
- DNS lookup timeouts may cause MX/SPF/DMARC checks to fail or return incomplete results
- Unknown or very new domains may not resolve, producing uncertain deliverability status
- Rate limits or payment failures (HTTP 402) block the request
- Disposable provider lists may not include every burner service, producing false negatives
