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。

headers
Authorization: Bearer jv_live_your_key_here
Content-Type: application/json

Core 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。

  • Authorization: Bearer jv_live_…
  • Content-Type: application/json

例

curl
curl https://jevtypesafe.org/api/v1/decide \
  -H "Authorization: Bearer jv_live_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "jev",
    "state": {
      "ticket": "I was charged twice and nobody has replied for 3 days.",
      "channel": "email"
    },
    "questions": {
      "route": {
        "type": "choice",
        "instructions": "Where should this go?",
        "criteria": { "billing": "money", "bug": "broken", "account": "login" }
      },
      "urgency": {
        "type": "score",
        "instructions": "How urgent is this?",
        "criteria": ["routine", "today", "urgent", "critical"]
      },
      "escalate": {
        "type": "noul",
        "instructions": "Escalate to a human now?"
      }
    }
  }'

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。

choice
"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。

score
"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。

noul
"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.

box
"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.

assets + box
curl https://jevtypesafe.org/api/v1/decide \
  -H "Authorization: Bearer jv_live_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{
    "state": { "photo": "product-shot" },
    "assets": {
      "product-shot": {
        "type": "image",
        "format": "png",
        "data_base64": "BASE64_PNG_HERE"
      }
    },
    "questions": {
      "region": {
        "type": "box",
        "instructions": "Find the primary product in photo"
      }
    }
  }'

レスポンス

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:

response
{
  "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。

POST https://jevtypesafe.org/api/v1/batch/decide

batch decide
curl https://jevtypesafe.org/api/v1/batch/decide \
  -H "Authorization: Bearer jv_live_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{
    "states": [
      "Passage A about API key rotation…",
      "Passage B about billing invoices…"
    ],
    "questions": {
      "relevant": {
        "type": "noul",
        "instructions": "Does this passage answer: How do I rotate my API key?"
      }
    }
  }'

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。

POST https://jevtypesafe.org/api/v1/gate

confidence gate
curl https://jevtypesafe.org/api/v1/gate \
  -H "Authorization: Bearer jv_live_YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{
    "answers": {
      "action": { "type": "choice", "choice": "allow", "confidence": 0.91 },
      "toxicity": { "type": "noul", "noul": 0.12 }
    },
    "policy": {
      "min_confidence": 0.55,
      "noul": { "toxicity": { "block_above": 0.85, "review_above": 0.4 } },
      "choice": { "action": { "allow": ["allow"], "block": ["block"], "review": ["review"] } }
    }
  }'

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

カテゴリ固定テンプレート — Core decide と同じ Bearer キーとプリペイド計量。ドメインフィールドを送り、構造化決定を返します。生の上流キーは不要。
