Email Address Check — syntax, MX, disposable, role ✓ Verified Official

by FiatDock · $0.001 / call

About this service

A pay-per-call MCP tool that answers whether an email address is worth sending to: syntax, the domain's DNS (MX, then A/AAAA), disposable-provider and role-mailbox lists, a free-provider flag, a typo suggestion (gmial.com -> gmail.com), a normalized form (Gmail dots and +tags collapsed), and a risk verdict — low / medium / high / undeliverable — with reasons. No SMTP probe: it vouches for the domain, never the mailbox. An invalid address is a paid verdict (that is the answer); a DNS failure answers 502 and is not charged. Tool: email_check — $0.001 USDC/call via x402 (paid automatically by the fiatdock-mcp package). Non-custodial; read-only; no address is stored.
