How this service works
Enterprise SOCKS5 proxy pool (540K+ proxies, 146 countries) and real-time email validation. Pay per use in USDC on Base mainnet. No subscription required.
Output
Returns a JSON object with the validated email address, a boolean indicating overall validity, whether MX records were found for the domain, whether the address belongs to a known disposable/temporary email provider, and whether the address is considered deliverable.
Example use cases
Signup form fraud prevention
“Before creating an account for this user, can you check if 'freestuff99@mailinator.com' is a real deliverable email or a throwaway disposable address?”
CRM data quality check
“I have a lead who gave me the email 'sarah.jones@globex.io' — can you verify it's actually valid and that the domain accepts mail before I reach out?”
Pre-send campaign validation
“I'm about to send an outreach email to 'contact@startupxyz.com' — can you confirm it's deliverable and not going to bounce?”
Technical details
Endpoint
GEThttps://gatewaypay.online/x402/email/validate/%7Bemail%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use, no-subscription email validation with disposable address detection and MX record verification returned in a single structured response. Ideal for agents that only occasionally validate emails and want to avoid monthly subscription costs. Useful for signup fraud prevention, CRM hygiene, and pre-send deliverability checks where real-time results are required.
Side effects
- Malformed email input may return valid:false without detailed diagnostics
- Disposable provider databases may be outdated, causing false negatives
- MX record checks depend on DNS availability and may time out
- Payment failure (402) if USDC balance is insufficient on Base mainnet
- Cold/new domains may have MX records but not be truly deliverable
