GET /enrich/email

live

Validate and classify an email DOMAIN from public DNS: MX hosts + mail-provider, SPF and DMARC policy, plus disposable / free-webmail / role-account flags and a deliverability signal. No SMTP probing of individual mailboxes (privacy + ToS).

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
