250 free calls / period · no credit card

Stop paying to email addresses that do not exist.

One REST call tells you whether an address can actually receive mail - syntax, MX reachability, disposable providers, role accounts, typos - plus checksum validation for CPF, CNPJ, IBAN, VAT, cards, ISBN and EAN, and phone parsing to E.164.

What you get

Email verification

RFC 5322 syntax, live MX with the RFC 7505 null-MX rule, 190 disposable providers, role accounts, gibberish detection, typo correction and a 0-100 deliverability score.

Identity & finance

CPF, CNPJ, IBAN (mod-97 across 80+ countries), EU VAT with national checksums, card Luhn + issuer BIN, ISBN-10/13, EAN-13, US EIN. Pure algorithms - no registry fees, no rate limits.

Phone numbers

Parse to E.164, country detection, national-number length rules, line-type inference and national formatting for the markets that matter.

Drop-in widget

One script tag puts the same typo and disposable detection inline in your own signup form - no account needed. See it.

Built to be integrated

Predictable JSON, idempotency keys, gzip, per-plan rate limits with Retry-After, batch endpoint, and an OpenAPI document.

Honest about the limits

We do not do SMTP callback verification. Mailbox-level probing is unreliable (catch-all domains, greylisting, tarpits) and gets sending IPs blocklisted. We tell you what is provable - syntax, DNS reachability, provider class, checksum validity - and we label everything else risky or unknown instead of inventing certainty.
