# Decision Kernel

> The judgment API — a decision that was too expensive per row now fits in your pipeline.

Decision Kernel exposes TypeSafe Jev (a System One decision model) as a fast,
calibrated, low-cost judgment API. Send text; get department (triage), urgency,
spam, tone, and whether it needs human review — all in one request, ~0.5s, with
explicit confidence.

Built on Cloudflare Workers. Judgment proposals only — no money movement, no
financial/medical/legal accountability (classification + routing suggestions only).

## For AI agents
