Two simple REST endpoints. Sign up, grab an API key, and start validating deliverability or discovering emails from a name + domain — instantly.
Syntax, DNS/MX and SMTP checks in one call. Know if an address is deliverable before you send.
Give us a full name and domain. We try 17 permutations and return the first valid address.
Simple monthly plans. Every plan includes both endpoints and catch-all resolution.
Overages billed at $0.008 per additional call. Catch-all resolution depth is capped at 1 on Starter, 3 on Growth, and 5 on Scale and Enterprise.
Authenticate every request with the x-api-key header.
/api/public/v1/verify-emailVerify a single email address.

}/api/public/v1/find-emailFind a person's email from name + domain. Stops at the first valid match. Optional `depth` (1-5, default 1) sets how many patterns get deep-verified on catch-all domains.
