Overview

Kiprio’s Email Validate checks email addresses — syntax, disposable, and MX records. Auth is an API key.

Note (verified 2026-08): the endpoint 301-redirects to the trailing-slash version (/v1/email-validate/) — follow redirects (curl -L) for clean responses.

Quick Start

Validate (replace YOUR_KEY):

curl -L "https://kiprio.com/v1/[email protected]&apiKey=YOUR_KEY"
{
  "email": "[email protected]",
  "valid": true,
  "disposable": false,
  "mx": "aspmx.l.google.com"
}

Authentication

  • Register at kiprio.com → API key.
  • Send it as the apiKey query parameter.

Rate Limits & Notes

  • Free tier with limits (check the docs); paid plans scale.
  • Follow the 301 to the canonical URL (verified).

FAQ

Is Kiprio free? Free tier with limits; more is paid.

Why 301? The endpoint canonicalizes to a trailing slash (verified) — use curl -L.

What does it check? Syntax, disposable domains, and MX records.
