Description
JEV API is designed to facilitate fast, typed decisions within software applications. Unlike traditional models that generate text, JEV API focuses on converting complex application states into bounded decisions. Developers can define legal answers, and JEV evaluates them to return a selected answer along with a probability distribution and confidence signal.

The API features three main components: Noul, Choice, and Score. Noul provides a probability for yes-or-no statements, Choice selects an option from a set and returns the probability distribution, and Score evaluates an ordered scale, preserving uncertainty across levels. This structured approach allows developers to maintain control over permissions, thresholds, retries, logs, and side effects while using JEV for bounded judgment.
JEV API is particularly useful for scenarios where outcomes are known, decisions are repetitive, and software requires probability rather than prose. It is ideal for agent systems, safety gates, operations scoring, and quality verification. The API is accessible through BeatAPI, where developers can manage accounts, billing, and API keys.
Pricing for JEV API is available on BeatAPI, offering a free tier with account rate limits and a paid option. While JEV primarily supports English, it can handle other languages, though accuracy may vary. Developers are encouraged to test their language and domain before relying on thresholds. JEV API is developed by TypeSafe AI and is part of their System One model, focusing on fast, direct judgments over declared options.
