Endpoint
api.kadec0.xyz/v1/email-validate
Email validation and email list cleaning. Checks each email address for RFC syntax, a live MX record lookup returning the real mail hosts, disposable-domain detection, role-account flags (info@, sales@, noreply@), and a free-provider flag, rolled into a per-address ok/risky/invalid verdict with reasons. Batch up to 25 email addresses per call. Domain-level DNS only, no SMTP mailbox probe. Keyless.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
