Email Verify

by Forest Web in Email & messaging

x402 APIPassing, checked 2 h ago

Verify email syntax and public DNS readiness with a bounded deterministic preflight. Forest checks normalized syntax, MX/address records including explicit null MX, and curated role/free/disposable-domain signals, then returns a conservative safe-to-attempt decision. It never connects to SMTP, sends mail, authenticates, stores customer mailboxes or claims that a mailbox exists. Base mainnet USDC
