Pricing questions
Is there really a free tier?
Yes — 1,000 events a month, forever, no card required. It includes all five checks and verdicts so you can evaluate Kaidn on your own traffic. AI reasons and intelligence insights unlock on paid plans.
How am I billed, and what about tax?
Paid plans are billed in advance, monthly or annually, and renew automatically until you cancel. Payments are processed by Paddle, our Merchant of Record, which adds any applicable VAT or sales tax at checkout and sends your receipt. We never see your full card details.
What counts as an event?
One call to POST /v1/score is one event. The free-tool checkers and dashboard views do not count against your event allowance.
What happens if I go over my plan's limit?
We'll let you know before it bites. Depending on your plan we may throttle, queue overage for billing at the published rate, or ask you to upgrade — we won't silently stop scoring your traffic.
Can I cancel or get a refund?
Cancel anytime from your dashboard — you keep access until the end of the period you’ve paid for. Your first paid subscription is covered by a 14-day money-back window. See the Refund Policy for details.
Do you offer annual or custom pricing?
Annual billing and higher-volume or custom plans are available — email support@kaidn.io and we’ll sort it out. No sales call required.
