GET /validate-email

live

Validate email address: checks syntax, whether the domain exists and accepts mail (MX records), disposable or temporary email domains, role addresses (info@, admin@), free webmail providers and SPF/DMARC presence, then returns deliverable / risky / undeliverable with the reason. Email validation for signups, lead lists and CRM cleaning, no API key. $0.01 per address.

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