How this service works
Pay-per-call data & tool APIs
Output
Returns a JSON object with a results array containing per-email details: syntax validity, MX record presence and list, deliverability verdict (e.g. 'valid_syntax_and_mx'), detected email provider, disposable flag, role account flag, catch-all risk, domain resolution status, mailbox check status, and timestamp. Meta includes run time and item count.
Example use cases
Pre-send list hygiene check
“Before I send this marketing campaign, verify that user@acmecorp.com is a valid deliverable email — I need to know if the syntax is correct, if the domain has MX records, and whether it's a disposable or role address.”
Signup form abuse prevention
“A new user just registered with the email burner123@mailnull.com — can you check if it's a disposable or throwaway email address so I can decide whether to block the signup?”
B2B prospect email validation
“I have a sales prospect with the email info@startup.io — verify if it's a real deliverable address, whether it's a role account, and what email provider they're using.”
Technical details
Endpoint
POSThttps://api.timzinin.com/api/email-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email validation that goes beyond syntax checking to include MX record lookup, disposable email detection, and role account flagging — without requiring a subscription. Ideal for agents validating individual addresses on demand rather than batch list processing.
Side effects
- Invalid or malformed email format returns syntax error verdict
- Domain with no MX records returns mxFound: false
- Network timeout on DNS lookup may return incomplete results
- Payment failure (x402) results in no response if USDC balance insufficient
- Catch-all domains cannot confirm individual mailbox existence so mailboxChecked remains false
