GET /email/verify
live
Email verification / validation API for lead lists (up to 20 addresses per call, ~1 s): syntax, domain mail setup (MX), mailbox provider (Google, Microsoft, Zoho, gateways), disposable / temporary domains (~10k), free webmail, role accounts (info@, sales@), typo suggestions (gmial.com -> gmail.com). Verdict valid / risky / invalid + score. No SMTP probing, no mail sent.
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
