# 6.4 路由 API（Auto 模式）

## **6.4 路由 API（Auto 模式）**

**端点：** `POST /v1/route`

专用路由查询接口，在发送实际请求前先查询平台推荐的模型（不消耗实际 Token）：

```
curl https://api.tooken.ai/v1/route \
  -H "Authorization: Bearer sk-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "task_type": "code_generation",
    "estimated_input_tokens": 2000,
    "constraints": {
      "max_cost_credits": 50,
      "max_latency_ms": 5000,
      "required_languages": ["python", "javascript"]
    }
  }'
```

**响应：**

```
{
  "recommended_model": "claude-opus-4",
  "reasoning": "代码生成任务，Claude Opus 在 Python/JavaScript 综合表现最佳",
  "estimated_cost_credits": 38.5,
  "estimated_latency_ms": 3200,
  "alternatives": [
    {
      "model": "deepseek-v3",
      "estimated_cost_credits": 5.5,
      "quality_trade_off": "代码质量约 85% 水平，成本降低 86%"
    }
  ]
}
```
