每次成功的调用都会返回 HTTP `200`。**`outcome_code`** 字段会告诉您实际发生了什么，例如区分真实的生物识别不匹配（`BIOMETRIC_NO_MATCH`）与无法读取的自拍照（`BIOMETRIC_IMAGE_UNUSABLE`）。所示的 `status` 是默认功能状态；您配置的[部分匹配/无匹配操作](https://docs.didit.me/zh/core-technology/database-validation/database-validation-warnings.md)可以覆盖它。

**`MATCH`**：登记机构确认了身份，且所有被检查的字段均匹配。

```json 200 OK — MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "AUS",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "aus_vevo",
      "service_name": "Australia VEVO",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "identification_number": "SAMPLE-ID-12345",
        "name_match_score": "1.000",
        "verifications": {
          "date_of_birth": true,
          "full_name": true,
          "identification_number": true
        }
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "full_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`PARTIAL_MATCH`**：已找到识别号码，但一个或多个个人字段（通常是姓名或出生日期）未完全匹配。

```json 200 OK — PARTIAL_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "AUS",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "aus_vevo",
      "service_name": "Australia VEVO",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "identification_number": "SAMPLE-ID-12345",
        "name_match_score": "1.000",
        "verifications": {
          "date_of_birth": true,
          "full_name": false,
          "identification_number": true
        }
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "no_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`NO_MATCH`**：登记机构未返回与所提交数据匹配的结果。

```json 200 OK — NO_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "AUS",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "aus_vevo",
      "service_name": "Australia VEVO",
      "source_data": {
        "date_of_birth": "NO_MATCH",
        "full_name": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "date_of_birth": "no_match",
        "full_name": "no_match",
        "identification_number": "no_match"
      }
    }
  ]
}
```

## 返回数据

`source_data` 中实际返回的字段取决于登记机构返回的内容。`aus_vevo` 的生成示例目前记录了以下标准化结构：

* `date_of_birth`
* `identification_number`
* `name_match_score`

## 定价与 SLA

仅当 Didit 从校验数据源收到确定性结果时，才对澳大利亚 VEVO 查询计费。

* **每次调用价格：** \$0.32 美元。
* **计费：** 按每次成功的查询计费。登记机构无法访问、必填字段缺失或请求在到达数据源之前被拒绝时，不收费。
* **延迟：** 典型 p95 \< 2 秒。
* **可用性：** Didit 侧每季度 99.9%；下游数据源的可用性因国家和数据集而异。
