# 危地马拉 DPI + 人脸比对（RENAP）API：身份匹配

> 通过 Didit 查询危地马拉权威数据库：DPI + 人脸比对（RENAP）。按次计费，起价 $0.40，无合同、无最低消费。

核验危地马拉 CUI 是否存在于国家登记库（RENAP）中，并将申请人的自拍照与 RENAP 官方照片进行比对，同时将持有人的姓名和出生日期与登记库记录进行比较。Didit 通过 `POST /v3/database-validation/` 提供此服务，您可以将提交的数据与权威来源进行核对，并获得标准化的比对结果。

## 请求体参数

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

此数据库服务的 ISO 3166-1 alpha-3 国家代码。

示例：`GTM`

**services** `string` *required* (default: gtm\_dpi\_facial)

包含此服务 ID 的数组。指定该服务可确保请求限定到这一特定数据库。

示例：`gtm_dpi_facial`

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

终端用户对此服务的明确同意。

示例：`true`

**document\_number** `string` *required* (default: 1234567890101)

从用户处提取或由用户提供的证件号码。

示例：`1234567890101`

**selfie** `file` *required*

要上传的用于生物识别数据库核验的自拍照文件。支持的格式：JPEG、PNG 或 WebP。

示例：`@./selfie.jpg`

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

需要核验的名字。

示例：`John`

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

需要核验的姓氏。

示例：`Doe`

**date\_of\_birth** `string` (default: 1990-01-01)

出生日期，格式为 `YYYY-MM-DD`。

示例：`1990-01-01`

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

您为该用户设定的稳定用户标识，例如您的内部用户 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

* 危地马拉 DPI（恰好 13 位数字）
* `document_number` 只能包含数字；发送请求前请删除空格、连字符和标点符号。
* `document_number` 长度必须恰好为 13 个字符。
* `document_number` 必须匹配 `\d{13}`。

每次成功的调用都返回 HTTP `200`。**`outcome_code`** 字段说明实际发生的结果，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` 为默认功能状态；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`**：登记库确认了身份，且所有检查的字段均已匹配。

```json 200 OK — MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "GTM",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "gtm_dpi_facial",
      "service_name": "Guatemala - DPI + face match (RENAP)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "document_expiration_date": "2031-11-24",
        "face_match": true,
        "face_match_score": 98.5,
        "first_name": "JOHN",
        "full_name": "JOHN DOE",
        "gender": "M",
        "identification_number": "1234567890101",
        "last_name": "DOE"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "full_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`PARTIAL_MATCH`**：已找到证件号码，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": "GTM",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "gtm_dpi_facial",
      "service_name": "Guatemala - DPI + face match (RENAP)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "document_expiration_date": "2031-11-24",
        "face_match": true,
        "face_match_score": 98.5,
        "first_name": "JOHN",
        "full_name": "JOHN DOE",
        "gender": "M",
        "identification_number": "1234567890101",
        "last_name": "DOE"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "no_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`NO_MATCH`**：登记库未返回与所提交数据匹配的记录。

```json 200 OK — NO_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "GTM",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "gtm_dpi_facial",
      "service_name": "Guatemala - DPI + face match (RENAP)",
      "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"
      }
    }
  ]
}
```

**`BIOMETRIC_NO_MATCH`**：人脸比对分数低于接受阈值，即自拍照与登记库照片不是同一人。

```json 200 OK — BIOMETRIC_NO_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "GTM",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "BIOMETRIC_NO_MATCH",
      "service_id": "gtm_dpi_facial",
      "service_name": "Guatemala - DPI + face match (RENAP)",
      "source_data": {
        "date_of_birth": "NO_MATCH",
        "face_match": false,
        "face_match_score": 0,
        "first_name": "NO_MATCH",
        "identification_number": "NO_MATCH",
        "last_name": "NO_MATCH"
      },
      "validation": {
        "date_of_birth": "no_match",
        "full_name": "no_match",
        "identification_number": "no_match"
      }
    }
  ]
}
```

**`DOCUMENT_NOT_FOUND`**：所提交的证件号码在登记库中没有对应记录。

```json 200 OK — DOCUMENT_NOT_FOUND theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "GTM",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "DOCUMENT_NOT_FOUND",
      "service_id": "gtm_dpi_facial",
      "service_name": "Guatemala - DPI + face match (RENAP)",
      "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"
      }
    }
  ]
}
```

**`DECEASED`**：身份已匹配，但登记库将该人员标记为已故。

```json 200 OK — DECEASED theme={null}
{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "GTM",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "DECEASED",
      "service_id": "gtm_dpi_facial",
      "service_name": "Guatemala - DPI + face match (RENAP)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "document_expiration_date": "2031-11-24",
        "face_match": true,
        "face_match_score": 98.5,
        "first_name": "JOHN",
        "full_name": "JOHN DOE",
        "gender": "M",
        "identification_number": "1234567890101",
        "last_name": "DOE"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "full_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

## 返回数据

`source_data` 中实际返回的字段取决于登记库返回的内容。`gtm_dpi_facial` 的自动生成示例目前记录了以下标准化结构：

* `date_of_birth`
* `document_expiration_date`
* `face_match`
* `face_match_score`
* `first_name`
* `full_name`
* `gender`
* `identification_number`
* `last_name`

## 定价与 SLA

危地马拉 - DPI + 人脸比对（RENAP）查询仅在 Didit 从核验来源收到确定结果时计费。

* **单次调用价格：** \$0.40 USD。
* **计费方式：** 按每次成功的查询计费。登记库无法访问、必填字段缺失或请求在到达数据源前被拒绝时，不收费。
* **延迟：** 典型 p95 低于 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。
