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://company-enrich.agentdiet.dev/v1/email)
Output
Returns a structured object indicating whether the email address passes syntax checks, whether the domain is associated with a known disposable/burner provider, whether it is a role account (e.g. admin@, support@), and live DNS lookup results for MX, SPF, and DMARC records indicating overall deliverability health.
Example use cases
Signup fraud prevention screening
“Before creating an account for the user who signed up with temp-mail123@guerrillamail.com, check if that email is from a disposable or burner provider and whether it has valid MX records.”
Sales outreach list cleanup
“I'm about to send a cold outreach sequence — can you validate that cto@startupxyz.io is a real deliverable address with proper MX and DMARC records, and not a role or catch-all account?”
Email infrastructure health audit
“Check the email security posture for contact@bigclient.com — I need to know if the domain has valid SPF and DMARC DNS records set up and whether the address is actually reachable.”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call check of both email syntax and live DNS deliverability signals (MX, SPF, DMARC) along with disposable-provider and role-account detection — especially in B2B lead enrichment, CRM hygiene, or signup fraud prevention workflows where a fast, low-cost per-email validation is needed without spinning up a full email verification service.
Side effects
- Missing or malformed email parameter returns a validation error
- DNS lookup timeout if the domain's nameservers are unresponsive
- Unrecognized TLD or private domain may produce incomplete DNS results
- Payment failure via x402 if USDC balance is insufficient ($0.005 per call)
- Disposable provider database may not cover newly created burner services
