Infrastructure pricing.

Common questions

What counts as a "decision record"?
Any AI decision event captured by the UTP pipeline — a credit scoring output, a loan approval, a risk classification, a fraud detection event. We count the evidence record written to the ledger, not API calls or model invocations.
Do I need to change my AI models or infrastructure?
Your models do not change. Your integration sends decision events to KairoNull by REST API, webhook or the Python and Node.js SDKs, so some code in your workflow changes. A first test record takes a few lines; a real workflow depends on the system and is scoped in advance.
Is there a free trial?
We offer a 30-minute evidence briefing where we walk through the pipeline with your governance context. Pilot deployments are scoped on a case-by-case basis during the initial phase.
What about data sovereignty?
Today the evidence ledger is hosted by KairoNull in one EU Supabase project. Hosting inside your own infrastructure is not a standard service; it would be scoped and agreed in writing before any commitment.
