How this service works
Email verification API: syntax check + DNS MX record lookup + disposable email detection. Validate email lists, catch bounces. $0.001/call, USDC on Base. No account or API key needed.
Output
Returns whether the email passes syntax validation, whether the domain has valid MX DNS records (meaning it can receive mail), and whether the address is from a known disposable/throwaway email provider — together forming a deliverability verdict.
Example use cases
Pre-send list scrubbing for email campaign
“Before I send this newsletter, can you check if subscriber@tempmail.io is valid — I want to know if it passes syntax, has working MX records, and whether it's a throwaway address?”
Blocking disposable emails at signup
“A new user just registered with user123@guerrillamail.com — can you tell me if that's a disposable or fake email so I can decide whether to block the account?”
CRM data quality audit
“I've got the email address contact@bigcorp.net in my CRM — can you verify it's syntactically correct, the domain actually accepts mail, and it's not a disposable provider?”
Technical details
Endpoint
POSThttps://api.mekongtradeintel.com/emailverify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-account-required email validation that combines three checks (syntax, DNS MX, disposable detection) in a single call for $0.001 USDC. Ideal for agents that need to validate individual emails on-the-fly without managing API keys or subscriptions. Prefer this over full SMTP handshake validators when speed matters and you don't need inbox-level confirmation.
Side effects
- Invalid or missing email query parameter returns an error response
- DNS lookup timeout if the email domain's nameservers are slow or unresponsive
- False negatives on newly created disposable domains not yet in the blocklist
- Payment failure or insufficient USDC balance prevents the call from completing
- Malformed email strings may return syntax-fail without attempting DNS lookup
