Retail packs meter input on this host (up to $0.42/M; output free). You pay for instant access, prepaid metering, playground/tools/batch/editor, and keys that never expose upstream credentials. Larger packs show lower $/M. Packs are prepaid credits metered 1:1 for Jev; OpenAI Decisions debits ceil(input_tokens × 3) from the same balance — check usage.billed_tokens on each response.

输入 token: $0.175–$0.42/M
输出 token: 免费
单次决策（均值）: ≈$0.0004
延迟: 70–500ms

各档大约能跑多少次

按典型分诊约 952 token/次（$0.42/M 时约 $0.0004）估算。从小包接线开始，流量真实后再升级。

$5 入门 ≈ 12,500 次典型 /decide（接线 + 冒烟）
$100 Production 及以上解锁更高 RPM 与日烧额度
state 更短 → 同样金额次数更多；一次多问题仍只算一轮

Decide 次数对比

先从 $5–$20 开始；离开 staging 时升一档——单价更低、限额更高。

调用托管 decide API

预付并在「账户」创建 jv_live_ 密钥后，向 /api/v1/decide 发起 POST。同一余额也用于现成工具。

curl

curl https://jevtypesafe.org/api/v1/decide \
  -H "Authorization: Bearer jv_live_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{"state":"Customer: my card was charged twice",
       "questions":{"topic":{"type":"choice",
         "instructions":"Route this message",
         "criteria":{"billing":"money","bug":"broken","account":"login"}}}}'

Python

import os, requests

r = requests.post(
    "https://jevtypesafe.org/api/v1/decide",
    headers={"Authorization": f"Bearer {os.environ['JEV_API_KEY']}"},  # jv_live_...
    json={
        "state": "Customer: my card was charged twice",
        "questions": {
            "topic": {
                "type": "choice",
                "instructions": "Route this message",
                "criteria": {"billing": "money", "bug": "broken", "account": "login"},
            }
        },
    },
)
print(r.json())

TypeScript

const r = await fetch("https://jevtypesafe.org/api/v1/decide", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.JEV_API_KEY}`, // jv_live_...
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    state: "Customer: my card was charged twice",

        instructions: "Route this message",

});
console.log(await r.json());

创建 API 密钥 →API 接入指南

实际含义

输入 token 单价为 $0.42/百万时，典型分诊类决策约 $0.0004（与公开基准一致）。输出免费，因此一次调用里多问几个问题仍然便宜。

1,000 次决策 ≈ $0.40
100 万次决策 ≈ $400
匿名访客可免费真调 API 运行工具 5 次（免注册）— 先试用再购买
注册账户每月约赠 10k 输入 token（冒烟测试，非生产额度）
在「账户」创建 jv_live_ API 密钥，调用 /api/v1/decide、batch、gate 或现成 /api/v1/*——与工具共用同一预付余额

你买到的是什么（以及不是什么）

你买的是本非官方社区托管站的预付容量：即时 jv_live_ 密钥、托管 decide/batch/gate 与现成模板——无需官方 waitlist。不是 TypeSafe SLA，也不是原始上游密钥（留在本站服务器）。我们与 TypeSafe AI 无隶属关系。
