POST /email-verify-api

open

Verifies an email address with syntax, MX, disposable-domain, role-account, SPF, DMARC, and DKIM checks. Same DNS-safe email deliverability backend as email-verify, indexed for agents searching exact email verification wording. Use it as an email verify API or to validate email address input.

Verdict: not verified by an unpaid GET. 200: serves without a payment challenge. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://x402.agentutility.ai/email-verify-api' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. 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.
