鉴权
购买预付包（或使用每月赠送 token）后，在「账户」创建密钥。
Authorization: Bearer jv_live_your_key_here
Content-Type: application/jsonCore API — /v1/decide
每次调用均为 POST 到 https://jevtypesafe.org/api/v1/decide，使用 Bearer 鉴权。把密钥放在环境变量 JEV_API_KEY（切勿提交进仓库）。

请求体
两个必填字段（另可加 beta assets）：
- state — 字符串、对象或数组（工单、聊天 JSON、记录）。序列化后最长 8,000 字符。
- questions — 名称 → 问题对象。instructions 可以是字符串或结构化 JSON。同一次请求共享 state。
- assets（可选，beta）— 具名图片 { type: "image", format, data_base64 }。可在 state / instructions 中引用。model（可选）— "jev"（默认，1× 扣费）或 "openai-decisions"（3×：billed_tokens = ceil(input_tokens × 3)）。
问题类型（Choice / Score / Noul + beta Box）
Image inputs and Box questions are beta and dreamer-ready, not recommended for production.（图片输入与 Box 为 beta / dreamer-ready，不建议用于生产。）
choice — 单选
传入带标签的 criteria 映射（值可为 null）。响应含获胜键、各选项概率与置信度。
"topic": {
"type": "choice",
"instructions": "What is the primary issue?",
"criteria": {
"billing": "billing or payment problem",
"bug": "the product is broken",
"account": "login or access"
}
}score — 量表打分
传入有序 criteria 数组（2–10 档）。响应含数值分数与各档分布。
"severity": {
"type": "score",
"instructions": "How urgent is this?",
"criteria": [
"routine",
"handle today",
"urgent",
"critical, about to churn"
]
}noul — 校准的是/否
必填 instructions；可选 criteria { true, false }。响应为 [0, 1] 概率。
"escalate": {
"type": "noul",
"instructions": "Escalate to a human immediately?"
}box — 边界框（beta）
仅 Jev 1.14。返回单个 box { top, bottom, left, right } 与 confidence。坐标为 0–1。
Image inputs and Box questions are beta and dreamer-ready, not recommended for production.（图片输入与 Box 为 beta / dreamer-ready，不建议用于生产。）
"region": {
"type": "box",
"instructions": "Find the primary object in photo"

}余额按 usage.billed_tokens 扣除，不要只看 input_tokens。Jev：billed_tokens = input_tokens（credit_multiplier 1）。openai-decisions：billed_tokens = ceil(input_tokens × 3)（credit_multiplier 3）。输出免费。例如 openai-decisions 上游 1000 input → 扣 3000 预付 credits。

- 速率约每密钥 120 次/分钟（另有 IP / 账户 / 全局上限）。
- 软燃烧上限（Starter）约每小时 5,000,000 token、每天 80,000,000 token。Production / Scale 余额档位更高 — 以 Account 页当前档位为准。
- 精简 state——按输入 token 计费。
- 多 state 用 /v1/batch/decide；单 state 多问题用一次 /v1/decide。
- 把 answers 交给 /v1/gate，在 agent 行动前自动 allow / review / block。
