Documentação da API Jev

Core decide para perguntas customizadas, mais APIs de aplicação prontas. Auth com chave jv_live_ — tokens de entrada pré-pagos, saída grátis. body.model opcional alterna Jev (padrão) ou OpenAI Decisions (tokens cobrados 3×). Clientes Choice / Score / Noul mantêm o mesmo schema de perguntas.

Autenticação

Crie chaves em Conta após comprar um pacote pré-pago (ou usar tokens mensais grátis).

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

Core API — /v1/decide

Cada chamada é um POST para https://jevtypesafe.org/api/v1/decide, autenticado com Bearer. Coloque a chave em JEV_API_KEY (nunca faça commit).

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

Exemplos

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?"
      }
    }
  }'

Teste sua chave — execute este request exato no endpoint ao vivo, uma vez:

Envia o request acima para https://jevtypesafe.org/api/v1/decide com sua chave e cobra uma decisão pequena (≈ $0.0004 média). A chave fica no navegador. Em produção, mantenha no servidor.

Corpo da requisição

Dois campos obrigatórios (mais model e assets beta opcionais):

  • state — string de contexto (texto do ticket, corpo do e-mail, review etc.). Máx. 8,000 caracteres.
  • questions — mapa de nomes → objetos de pergunta. Todas as perguntas no mesmo request compartilham o state e rodam em um round-trip.
  • assets (opcional, beta) — imagens nomeadas { type: "image", format, data_base64 }. Referencie nomes em state / instructions. model (opcional) — "jev" (padrão, 1×) ou "openai-decisions" (3×: billed_tokens = ceil(input_tokens × 3); lista ~$0.30/M).

Tipos de pergunta (Choice / Score / Noul + Box beta)

Image inputs and Box questions are beta and dreamer-ready, not recommended for production.

choice — escolher uma opção

Passe um mapa criteria de opções rotuladas. A resposta inclui a chave vencedora, probabilidades por opção e confiança.

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 — posição em uma escala

Passe um array criteria ordenado (2–10 níveis). Retorna score numérico mais distribuição pelos níveis.

score
"severity": {
  "type": "score",
  "instructions": "How urgent is this?",
  "criteria": [
    "routine",
    "handle today",
    "urgent",
    "critical, about to churn"
  ]
}

noul — sim / não calibrado

Sem criteria — só instructions. Resposta é probabilidade em [0, 1].

noul
"escalate": {
  "type": "noul",
  "instructions": "Escalate to a human immediately?"
}

box — bounding box (beta)

Somente Jev 1.14. Retorna um box { top, bottom, left, right } mais confidence. Coordenadas normalizadas 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"
}

Exemplo beta — 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"
      }
    }
  }'

Resposta

Respostas tipadas permitem ramificar no código — sem parsear JSON em string. Forma de exemplo:

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
  }
}

O saldo move por usage.billed_tokens, não só input_tokens. Jev: billed_tokens = input_tokens (credit_multiplier 1). openai-decisions: billed_tokens = ceil(input_tokens × 3) (credit_multiplier 3). Tokens de saída são grátis. Exemplo: 1000 input em openai-decisions remove 3000 créditos pré-pagos.

Batch decide — /v1/batch/decide

Envie vários states em uma chamada autenticada. As mesmas questions para cada linha. Medição pré-paga por decide upstream.

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

Passe answers do decide mais policy opcional. Retorna allow | review | block. Sem chamada upstream e sem queima de tokens.

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"] } }
    }
  }'

Erros e limites

  • Limite de taxa ≈ 120/min por chave (mais tetos de IP / conta / global).
  • Tetos suaves de burn (Starter) ≈ 5,000,000 tokens/hora e 80,000,000 tokens/dia. Saldos Production / Scale liberam tetos maiores — veja o tier em Conta.
  • Enxugue o state — você paga por token de entrada.
  • Agrupe várias perguntas em uma chamada para compartilhar o custo do state.
  • Use limiares de confidence / noul para tratar casos fáceis automaticamente e escalar o resto.

APIs de aplicação prontas
