402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.DESCRIPTION
Detects disposable and throwaway email addresses before they get through your signup form. Checks the email's domain against a 100k+ disposable-domain blocklist, flags role-style local-parts (admin@, info@, noreply@, support@), and verifies a live MX record via Cloudflare DNS-over-HTTPS so dead domains can't pass. Use it as a temp-mail, fake email, or 10minutemail filter, a Mailinator + Guerrilla Mail + Yopmail blocklist, fraud signup defense, role-account flagger, MX-record validator, or signup-form abuse guard.
