# 订单

通过 Orders 端点购买流量（住宅 / 移动）或 ISP 批次。不同产品使用不同子资源，但都共用 `/orders` 信封。

## 通用形态

```bash
curl -X POST -H "Authorization: Bearer API_KEY" \
     -H "Content-Type: application/json" \
     -H "Idempotency-Key: order-2026-05-28-001" \
     -d '{ "product": "residential", "gb": 50 }' \
     https://api.helodata.com/v1/orders
```

响应：

```json
{
  "id":         "ord_01HX2K3PQ4M5",
  "product":    "residential",
  "status":     "completed",
  "total_usd":  225.00,
  "details":    { "gb": 50, "price_per_gb": 4.50 },
  "created_at": "2026-05-28T10:00:00Z"
}
```

## 住宅 / 移动（按流量）

```bash
-d '{
  "product": "residential",        // 或 "mobile"
  "gb":      50
}'
```

带宽立即加入子账号池，账号下该产品的所有子账号共用。

## ISP 批次

ISP 订单会创建一个**批次**——一组专属静态 IP。

```bash
curl -X POST -H "Authorization: Bearer API_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "product":  "isp",
       "country":  "us",
       "city":     "newyork",
       "asn":      7922,
       "quantity": 20,
       "months":   1,
       "subuser":  "sub_01HX2K3PQ4M5"
     }' \
     https://api.helodata.com/v1/orders
```

返回订单信封 + `batch_id`（后续 IP 管理需用）：

```json
{
  "id":         "ord_01HXabc",
  "product":    "isp",
  "status":     "provisioning",
  "total_usd":  120.00,
  "details": {
    "batch_id": "bat_01HXabc",
    "quantity": 20,
    "country":  "us",
    "city":     "newyork",
    "asn":      7922,
    "expires_at": "2026-06-28T10:00:00Z"
  }
}
```

`status` 流转：`provisioning` → `completed`（T1 通常 1–5 分钟，长尾国家最长 24 小时）。
