EmailValidation API
EmailValidation API is a REST service for developers validating email addresses through web and API access.
What EmailValidation API is
EmailValidation API is a REST service for developers validating email addresses through web and API access. Each check examines syntax, DNS and MX records, SMTP reachability, disposable domains, role-based addresses, typo suggestions, and MX behavior. Real-time SMTP RCPT TO checks and FCrDNS-validated HELO are used for providers including Gmail, Outlook, and iCloud. Responses include confidence levels and reason codes for uncertain cases such as anti-probe or catch-all servers. Integration uses Bearer authentication without an SDK, with examples for PHP, Python, Node.js, Ruby, and Go. Typical latency is 80–400 ms per email; repeated checks of the same address within one hour are stated to return in under 10 ms. Every validation consumes one credit, including catch-all and anti-probe results. Bulk list upload and real-time form checks are available, while the asynchronous batch endpoint is described as coming soon. The maker is based in France.

Who it suits
EmailValidation API suits developers cleaning signup forms or mailing lists and preventing fake accounts. It fits integrations needing REST access, real-time checks, or bulk list uploads.
Verdict
