jev-go (guillemus)

Minimal unofficial Go SDK for Jev supporting Noul, Choice, Score, structured inputs and model listing.

View on GitHub ↗

Overview

This unofficial Go SDK for TypeSafe's Jev API keeps abstractions deliberately minimal. A client created with the API key calls SystemOne with a state and a map of questions, and returns answers such as the chosen category for a support message. It supports Noul, Choice and Score questions, structured state inputs and listing available models, with a configurable client for custom settings.

It requires Go 1.26 or newer and links to examples and the pkg.go.dev reference.
