# AIway Open API（codegen）

`BASE=https://www.ryfs.cn/api/v1`  
`Authorization: Bearer <sk_...>`  
`Content-Type: application/json`

```text
AI_SCHEDULER_URL=https://www.ryfs.cn/api/v1
AI_SCHEDULER_TOKEN=sk_xxx
```

Token 仅服务端。SDK：`https://www.ryfs.cn/sdk/aiway-client.ts` → `lib/aiway-client.ts`

| 方法 | 路径 | SDK |

## POST /run — Task

需 `modes.can_use_task`。提示词在 AIway，业务站只传字段。

```json
{ "task": "ping", "input": { "message": "hi" }, "trace_id": "optional" }
```

| 字段 | 必填 |
|------|------|
| `task` | 是 |
| `input` | 是（缺必填字段 → 400） |
| `trace_id` | 否 |
| `mode` | 否，默认 `task` |

成功：

```json
{
  "request_id": "uuid",
  "mode": "task",
  "output_text": "...",
  "output_json": {},
  "output_format": "json",
  "prompt_scope": "global",
  "usage": { "input_tokens": 0, "output_tokens": 0, "total_tokens": 0, "cost": 0, "model_id": "..." },
  "balance": 0
}
```

`output_json` 解析失败为 `null`；`output_format` 为 `json|text`；`prompt_scope` 为 `global|site`。

### 预置 task

## POST /chat/completions

OpenAI 兼容。计费同 Raw（需 `can_use_raw`）。

视觉表单：服务商=OpenAI 兼容；`model=google/gemini-2.5-flash`；`api_key=sk_...`；`base_url=https://www.ryfs.cn/api/v1`（不要填 `/api/v1/run`）。短名如 `gemini-2.5-flash` 可解析。

```json
{
  "model": "google/gemini-2.5-flash",
  "messages": [
    { "role": "system", "content": "" },
    {
      "role": "user",
      "content": [
        { "type": "text", "text": "" },
        { "type": "image_url", "image_url": { "url": "https://cdn.example.com/a.jpg" } }
      ]
    }
  ],
  "temperature": 0.7,
  "max_tokens": 2048
}
```

```json
{
  "id": "chatcmpl-uuid",
  "object": "chat.completion",
  "created": 0,
  "model": "google/gemini-2.5-flash",
  "choices": [{ "index": 0, "message": { "role": "assistant", "content": "" }, "finish_reason": "stop" }],
  "usage": { "prompt_tokens": 0, "completion_tokens": 0, "total_tokens": 0 },
  "request_id": "uuid"
}
```

错误体：`{"error":{"message":"...","type":"api_error","code":"502"}}`

## GET /account

```json
{
  "site_code": "",
  "site_name": "",
  "status": "active",
  "balance": 0,
  "month_quota": null,
  "month_used": 0,
  "month_remaining": null,
  "modes": {
    "task_mode_enabled": true,
    "raw_mode_enabled": true,
    "site_raw_enabled": true,
    "can_use_task": true,
    "can_use_raw": true
  }
}
```

`can_use_raw = raw_mode_enabled && site_raw_enabled`。`status!=="active"` 或 `balance<=0` 不要调 `/run`。

---

## GET /usage

Query：`from` `to`（ISO）`page` `page_size`（默认 20，最大 100）`task`（Raw 为 `raw`）。

```json
{
  "page": 1,
  "page_size": 20,
  "items": [{ "request_id": "", "task": "", "model_id": "", "input_tokens": 0, "output_tokens": 0, "total_tokens": 0, "cost": 0, "status": "", "created_at": "" }],
  "summary": { "total_calls": 0, "total_cost": 0, "total_tokens": 0 }
}
```

`GET /usage/{request_id}` 另含 `error_code` `error_message` `trace_id` `latency_ms`。

---

## 错误

`/run` `/account` `/usage`：

```json
{ "error": { "code": "402", "message": "Insufficient balance" } }
```
