Api Endpoint

P0 Email Verify

Use when you must check a list of email addresses before a mailing or import: up to 25 addresses in one POST, each checked exactly like /v1/email/verify (syntax, MX, disposable, role, free-provider and placeholder flags, verdict). DNS only, no SMTP mailbox probe. Fixed price per call for 1 to 25 addresses ($0.01 each at a full batch); bad input refused before any charge. $0.25 per call (USDC or USDT). Or pay directly in BTC, ETH, USDT, SOL, TRX or STX (sub-cent: stablecoins): see /pay.
