What it is
An unofficial PHP client for TypeSafe AI's System One API, letting PHP and Laravel developers ask typed questions about text or JSON and receive probabilities, labels, or rubric levels.
How it uses Jev
Jev answers Noul (yes/no probability), Choice (one of several labels), and Score (level on an ordered rubric) questions built fluently and keyed by name. The response exposes typed accessors like noul(), choice(), and score() to read the answers in code.
Primitives:choicescorenoul
Technique worth stealing
One call switches between TypeSafe and OpenRouter providers while keeping request and answer bodies identical.
Try it
composer require phox/typesafe-sdk-php, set TYPESAFE_API_KEY, then build a Client and call systemOne().
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.
