What it is
A collection of Go example programs demonstrating how to call TypeSafe's Jev (System One) HTTP API directly using only the Go standard library, since no official Go SDK exists. For Go developers exploring Jev.
How it uses Jev
Each example calls Client.SystemOne with a state string and a map of typed questions (Noul, Choice, Score). Jev returns calibrated probabilities and confidence per answer; examples use these to classify, score, route, or threshold decisions in code.
Primitives:choicescorenoul
Technique worth stealing
Fan out all possible questions in one request, then select relevant answers in code.
Try it
mise install; cp .env.example .env; mise run ex:all
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
