Jev Php
A small PHP 8.1 library, extracted from LLPhant, giving typed value objects for Jev's Noul, Choice and Score answers, with probabilities and token usage. Unofficial and community-built; you supply a TypeSafe API key, or point it at Laya.

Highlights
- Typed value objects for Jev's three question types: Noul (yes/no), Choice (label plus probabilities) and Score (rubric grades).
- NoulAnswer::isTrue(0.80) takes a confidence floor; ScoreAnswer exposes score, confidence, legend and probabilities; every answer includes token usage.
- Noul questions accept an optional criteria object via NoulCriteria; every answer includes token usage: inputTokens and outputTokens.
- Reads the key from JEV_API_KEY by default or an explicit JevConfig; LayaConfig points the same classifier at Laya with LAYA_URL and an optional LAYA_API_KEY.
- PHP ^8.1 with Composer; extracted from the larger LLPhant project and explicitly unofficial, not affiliated with TypeSafe AI.
Quickstart
php
composer require f-lombardo/jev-phpWatch out
Copy reviewed against the repo README on 2026-10-15. The README labels the project unofficial and requires your own TypeSafe API key, and it documents no pricing, latency or benchmark figures. The library focuses on one use case — state in, structured answers out — so retry, batching and streaming behaviour is not described.

A small PHP library extracted from the larger LLPhant project that gives typed access to Jev's classification APIs. It focuses on one use case: send a state — typically text — and receive structured answers through value objects.
composer require f-lombardo/jev-php, with PHP 8.1 or later and Composer. JevClassifier reads the key from the JEV_API_KEY environment variable by default, or you can pass it explicitly through new JevConfig(apiKey: 'your_api_key').
Community-built, and explicitly so: the README says jev-php is not affiliated with, endorsed by or sponsored by TypeSafe AI, and TypeSafe and Jev belong to their owner. It ships under LGPL-2.1 and you need your own TypeSafe API key to use it.
Build an array of typed questions — NoulType for yes/no, ChoiceType with label descriptions, ScoreType with ScoreCriteria levels — then call askQuestions(state, questions). Answers come back keyed by question name as NoulAnswer, ChoiceAnswer or ScoreAnswer objects.
ChoiceAnswer exposes choice, confidence and probabilities; NoulAnswer has isTrue(minTrueScore) so you can test a threshold such as isTrue(0.80); ScoreAnswer exposes score, confidence, legend and probabilities. Every answer also carries inputTokens and outputTokens usage metadata.
Yes. JevClassifier accepts a LayaConfig: set LAYA_URL to your Laya systemone endpoint and optionally LAYA_API_KEY, then construct the classifier with new JevClassifier(new LayaConfig()). Laya's documentation has a Docker quickstart for laya-serve, which exposes a Jev-compatible API.
PHP ^8.1, Composer and a Jev API key. The library does one thing — typed state-in, structured answers out for Noul, Choice and Score — and the README documents nothing beyond that, so retries, batching, streaming or production hardening are not described.
