jev_elixir

Small idiomatic Elixir client for Jev via TypeSafe or OpenRouter, with boolean ask? and analyze helpers.

Overview

jev_elixir is a compact Elixir interface for typed decisions with Jev. It exposes application-level functions such as Jev.ask?/2, which returns a real boolean against a threshold for use in case expressions or Phoenix controllers, and Jev.analyze/3 for richer questions. Provider adapters handle the wire format.

The first release supports TypeSafe's System One API and OpenRouter's alpha Decisions API (defaulting to typesafe/jev-1.13), both with Noul, Choice and Score. Configuration is done at runtime so the API key stays out of compiled releases, and calls can override provider, key, model, endpoint or timeout. The README's example marks a comment as spam when ask? passes at a 0.95 threshold.

How it works

  1. Add jev_elixir and configure provider and key in runtime.exs
  2. Call Jev.ask? or Jev.analyze with a state
  3. Adapter sends the request to TypeSafe or OpenRouter
  4. Branch on the boolean or typed result

Strengths

  • Idiomatic boolean API for Phoenix code
  • Two provider adapters
  • Keys kept out of compiled releases

Caveats

  • OpenRouter Decisions API is alpha and may change
  • Version 0.1.0

Getting started

Add `{:jev_elixir, "~> 0.1.0"}` and set `config :jev_elixir, provider: :typesafe, api_key: System.fetch_env!("TYPESAFE_API_KEY")`.

Frequently asked questions

Which providers are supported?

TypeSafe's System One API and OpenRouter's Decisions API.

What does ask? return?

A real boolean based on the Noul probability and your threshold.

How is the key handled?

Through runtime configuration so it is not compiled into releases.
