GET /email/verify

live

Email verification / validation API for lead lists (up to 20 addresses per call, ~1 s): syntax, domain mail setup (MX), mailbox provider (Google, Microsoft, Zoho, gateways), disposable / temporary domains (~10k), free webmail, role accounts (info@, sales@), typo suggestions (gmial.com -> gmail.com). Verdict valid / risky / invalid + score. No SMTP probing, no mail sent.

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

Try it (unpaid: shows the 402)

curl -si -X GET 'https://agent-data.centorprat.workers.dev/email/verify' -H 'accept: application/json'

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
