com.contrastcyber/api · Verify this server

One-call email validation combining syntax + MX records + disposable check + role-address detection (admin@/info@/...) + free-provider classification (gmail/outlook/yahoo/...). Use BEFORE adding an email to a contact list, sending an outbound message, or auditing a lead-list dump — replaces 2-3 tool calls (email_mx + email_disposable + manual role parse) with one structured response. Deliberately does NOT do SMTP `RCPT TO` deliverability probing — Hunter.io / NeverBounce-style mailbox enumeration is an ethical grey area we declined; use those services if you need that specific signal. role_address=true on `admin@`, `info@`, `noreply@`, `support@`, etc. (Gmail-style `+tag` is stripped before classification). free_provider=true on consumer-mailbox domains (B2B detection signal — a 'work' email at `@gmail.com` likely isn't a corporate user). Free: 30/hr, Pro: 500/hr. Returns {email, domain, syntax_valid, mx_records, disposable, disposable_provider, role_address, role_type, free_provider, summary}.
