# 澳大利亚结婚证 API - DVS 数据库核验

> Didit 提供澳大利亚 DVS 结婚证数据库核验，调用澳大利亚权威数据库查询，按次付费，起价 $0.75，无需合同，无最低消费。

根据 Document Verification Service (DVS) 校验输入数据。Didit 通过 `POST /v3/database-validation/` 提供此服务，方便您将提交的数据与权威数据源进行核对，并获得标准化的匹配结果。

## 覆盖范围

* **覆盖范围：** 100%\*
* **国家/地区：** 澳大利亚
* **服务 ID：** `aus_marriage_certificate`
* **数据领域：** 身份
* **类别：** CivilRegistry

## 输入

| 字段 | 必填 | 示例 |
| - | -: | - |
| `first_name` | 是 | `John` |
| `last_name` | 是 | `Doe` |
| `first_partner_name` | 是 | `Jamie` |
| `last_partner_name` | 是 | `Example` |
| `marriage_certificate_number` | 是 | `SAMPLE-MARRIAGE-12345` |
| `birth_registration_number` | 是 | `SAMPLE-BIRTH-12345` |
| `birth_registration_state` | 是 | `Sample State` |
| `birth_registration_date` | 是 | `1990-01-01` |
| `vendor_data` | 否 | `user-1234` |

* **必填输入：** `first_name`、`last_name`、`first_partner_name`、`last_partner_name`、`marriage_certificate_number`、`birth_registration_number`、`birth_registration_state`、`birth_registration_date`
* **可选输入：** `vendor_data`
* **同意：** 必需
* **工作流可用性：** 可在工作流中通过字段映射使用
* **覆盖范围：** 100%\*
* **价格：** 每次成功查询 \$0.75

在工作流中，`first_partner_name`、`last_partner_name`、`birth_registration_state` 和 `birth_registration_date` 不会印在身份证件上，因此没有任何步骤能单独产生这些值。请从问卷答案、Document AI 提取字段，或创建会话时您发送的值中采集这些数据，并在数据库核验步骤中分别映射。在完成映射之前，工作流编辑器会将此服务显示为禁用状态，并指出缺少的输入。运行时若缺少输入，该检查会在任何查询之前被跳过，因此您永远不会为无法查询的数据库付费。

## 请求体参数

**issuing\_state** `string` *required* (default: AUS)

此数据库服务使用的 ISO 3166-1 alpha-3 国家/地区代码。

示例：`AUS`

**services** `string` *required* (default: aus\_marriage\_certificate)

包含此服务 ID 的数组。固定服务可确保请求仅限于此特定数据库。

示例：`aus_marriage_certificate`

**consent** `boolean` *required* (default: true)

终端用户对此服务的明确同意。

示例：`true`

**first\_name** `string` *required* (default: John)

需要校验的名字。

示例：`John`

**last\_name** `string` *required* (default: Doe)

需要校验的姓氏。

示例：`Doe`

**first\_partner\_name** `string` *required* (default: Jamie)

此数据库服务所需的 `first_partner_name` 值。

示例：`Jamie`

**last\_partner\_name** `string` *required* (default: Example)

此数据库服务所需的 `last_partner_name` 值。

示例：`Example`

**marriage\_certificate\_number** `string` *required* (default: SAMPLE-MARRIAGE-12345)

此数据库服务所需的 `marriage_certificate_number` 值。

示例：`SAMPLE-MARRIAGE-12345`

**birth\_registration\_number** `string` *required* (default: SAMPLE-BIRTH-12345)

此数据库服务所需的 `birth_registration_number` 值。

示例：`SAMPLE-BIRTH-12345`

**birth\_registration\_state** `string` *required* (default: Sample State)

此数据库服务所需的 `birth_registration_state` 值。

示例：`Sample State`

**birth\_registration\_date** `string` *required* (default: 1990-01-01)

此数据库服务所需的 `birth_registration_date` 值。

示例：`1990-01-01`

**vendor\_data** `string` (default: user-1234)

您为该用户设置的稳定用户标识，例如内部用户 ID。Didit 使用它将独立检查关联到同一终端用户，并减少重复检测的干扰。

示例：`user-1234`

## 输入规则与校验说明

* 请按从用户或证件中采集的原样发送上述字段。
* Didit 会在调用数据库之前校验必填字段。在查询数据源之前被拒绝的请求不收费。

每次成功调用都返回 HTTP `200`。**`outcome_code`** 字段说明实际发生了什么，例如可以区分真正的生物识别不匹配（`BIOMETRIC_NO_MATCH`）与无法读取的自拍照（`BIOMETRIC_IMAGE_UNUSABLE`）。所显示的 `status` 是默认的功能状态；您配置的[部分匹配 / 不匹配操作](https://docs.didit.me/zh/core-technology/database-validation/database-validation-warnings.md)可以覆盖该状态。

**`MATCH`**：注册机构已确认身份，且所有被核对的字段均匹配。

```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_marriage_certificate",
      "service_name": "Australia - DVS – Marriage Certificate",
      "source_data": {
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe"
      },
      "validation": {
        "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_marriage_certificate",
      "service_name": "Australia - DVS – Marriage Certificate",
      "source_data": {
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe"
      },
      "validation": {
        "full_name": "no_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`NO_MATCH`**：注册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_marriage_certificate",
      "service_name": "Australia - DVS – Marriage Certificate",
      "source_data": {
        "full_name": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "full_name": "no_match",
        "identification_number": "no_match"
      }
    }
  ]
}
```

## 返回数据

`source_data` 中实际返回的具体字段取决于注册机构的返回内容。`aus_marriage_certificate` 生成的示例目前记录了以下标准化结构：

* `first_name`
* `identification_number`
* `last_name`

## 定价与 SLA

Australia - DVS – Marriage Certificate 查询仅在 Didit 从验证来源收到确定结果后计费。

* **单次调用价格：** \$0.75 USD。
* **计费方式：** 按成功查询计费。以下情况不收费：注册机构无法访问、缺少必填字段，或请求在到达数据源前被拒绝。
* **延迟：** 典型 p95 低于 2 秒。
* **可用性：** Didit 方面每季度的可用性为 99.9%；下游数据源的可用性因国家和数据集而异。
