API リファレンス
Jev API ドキュメント
カスタム質問用の Core decide と既存アプリケーション API。jv_live_ キーで認証 — プリペイド入力、出力無料。任意の body.model で Jev(デフォルト)または OpenAI Decisions(課金トークン 3×)を切替。Choice / Score / Noul クライアントは同じ質問スキーマのままです。
認証
プリペイドパック購入(または月次無料トークン使用)後、アカウントでキーを作成します。
Authorization: Bearer jv_live_your_key_here
Content-Type: application/jsonCore API — /v1/decide
各呼び出しは POST を https://jevtypesafe.org/api/v1/decide へ送り、Bearer で認証します。キーは JEV_API_KEY に置き、コミットしないでください。

console.log(await res.json());キーをテスト — ライブエンドポイントにこのリクエストを一度実行:
上記リクエストを https://jevtypesafe.org/api/v1/decide にキー付きで送り、小さな 1 決定分を課金します(平均 ≈ $0.0004)。キーはブラウザ内のみ。本番ではサーバー側に保管。
リクエスト本文
必須フィールドは 2 つ(任意の model と beta assets を追加可):
- state — コンテキスト文字列(チケット文、メール本文、レビューなど)。最大 8,000 文字。
- questions — 名前 → 質問オブジェクトのマップ。1 リクエスト内の全質問が state を共有し、1 往復で実行。
- assets(任意、beta)— 名前付き画像 { type: "image", format, data_base64 }。state / instructions から名前を参照。model(任意)— "jev"(デフォルト、1× 課金)または "openai-decisions"(3×:billed_tokens = ceil(input_tokens × 3);一覧約 $0.30/M)。
質問タイプ(Choice / Score / Noul + beta Box)
Image inputs and Box questions are beta and dreamer-ready, not recommended for production.
choice — オプションを 1 つ選択
ラベル付きオプションの criteria マップを渡します。レスポンスは当選キー、各オプション確率、信頼度を含みます。
"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 — スケール上の位置
順序付き criteria 配列(2–10 段階)を渡します。数値スコアと各段階の分布を返します。
"severity": {
"type": "score",
"instructions": "How urgent is this?",
"criteria": [
"routine",
"handle today",
"urgent",
"critical, about to churn"
]
}noul — 校正された yes / no
criteria なし — instructions のみ。レスポンスは [0, 1] の確率。
"escalate": {
"type": "noul",
"instructions": "Escalate to a human immediately?"
}box — バウンディングボックス(beta)
Jev 1.14 のみ。単一の box { top, bottom, left, right } と confidence を返します。座標は正規化 0–1。
Image inputs and Box questions are beta and dreamer-ready, not recommended for production.
"region": {
"type": "box",
"instructions": "Find the primary object in photo"
}Beta 例 — assets + box
Image inputs and Box questions are beta and dreamer-ready, not recommended for production.

型付き回答なのでコードで分岐できます — 文字列内 JSON のパース不要。例の形:
{
"model": "jev-1.14.0",
"answers": {
"route": {
"type": "choice",
"choice": "billing",
"confidence": 1.0,
"probabilities": { "billing": 1.0, "bug": 0.0, "account": 0.0 }
},
"urgency": {
"type": "score",
"score": 2.0,
"confidence": 0.9,
"probabilities": { "0": 0.05, "1": 0.1, "2": 0.7, "3": 0.15 }
},
"escalate": { "type": "noul", "noul": 0.72 }
},
"usage": {
"input_tokens": 180,
"billed_tokens": 180,
"output_tokens": 0,
"remaining_tokens": 11999820
},
"meta": {
"decide_model": "jev",
"credit_multiplier": 1
}
}残高は input_tokens だけではなく usage.billed_tokens で動きます。Jev:billed_tokens = input_tokens(credit_multiplier 1)。openai-decisions:billed_tokens = ceil(input_tokens × 3)(credit_multiplier 3)。出力トークンは無料。例:openai-decisions で入力 1000 → プリペイド 3000 減算。
Batch decide — /v1/batch/decide
認証済みの 1 回の呼び出しで多数の state を送信。全行で同じ questions。上流 decide ごとにプリペイド計量。

}
}
}'Confidence gate — /v1/gate
decide の answers と任意の policy を渡すと allow | review | block を返します。上流呼び出しなし、トークン消費なし。

}'エラーと制限
- レート制限 ≈ キーあたり 120/分(加えて IP / アカウント / グローバル上限)。
- ソフトバーン上限(Starter)≈ 毎時 5,000,000 トークン、毎日 80,000,000 トークン。Production / Scale 残高で上限が上がります — ティアはアカウントで確認。
- state を短く — 入力トークン単位で課金されます。
- 複数質問を 1 呼び出しにまとめ、state コストを共有。
- confidence / noul しきい値で簡単なケースを自動処理し、残りをエスカレーション。
既存アプリケーション API
