# 秘鲁 DNI 验证 API - 实时数据库核验

> Didit 提供秘鲁权威数据库核验，通过 Didit 身份基础设施验证 DNI。按次计费，起价 $0.20，无合同，无最低消费。

根据 RENIEC 民事登记处核验秘鲁 DNI。Didit 通过 `POST /v3/database-validation/` 提供此服务，便于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。输入格式：`personal_number` 填写秘鲁 DNI（恰好 8 位数字）。

## 覆盖范围

* **覆盖范围：** —
* **国家/地区：** 秘鲁
* **服务 ID：** `per_dni`
* **数据领域：** 身份
* **类别：** NationalIDRegistry

## 输入

| 字段 | 必填 | 示例 |
| - | -: | - |
| `personal_number` | 是 | `11111111` |
| `first_name` | 否 | `John` |
| `last_name` | 否 | `Doe` |
| `vendor_data` | 否 | `user-1234` |

* **必填输入：** `personal_number`
* **可选输入：** `first_name`、`last_name`、`vendor_data`
* **同意：** 不需要
* **工作流可用性：** 可在工作流中使用
* **覆盖范围：** —
* **价格：** 每次成功查询 \$0.20

## 请求体参数

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

此数据库服务的 ISO 3166-1 alpha-3 国家代码。

示例：`PER`

**services** `string` *required* (default: per\_dni)

包含此服务 ID 的数组。固定该服务可将请求限定在此特定数据库内。

示例：`per_dni`

**personal\_number** `string` *required* (default: 11111111)

特定国家/地区的个人身份编号。

示例：`11111111`

**first\_name** `string`

需要核验的名字。

示例：`John`

**last\_name** `string`

需要核验的姓氏。

示例：`Doe`

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

您为此人设置的稳定用户标识，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，并减少重复检测噪声。

示例：`user-1234`

## 输入规则与验证说明

* 秘鲁 DNI（恰好 8 位数字）
* `personal_number` 只能包含数字；发送请求前请去除空格、连字符和标点符号。
* `personal_number` 长度必须恰好为 8 个字符。

```

```python Python theme={null}
from didit import Didit

# Reads DIDIT_API_KEY.
client = Didit()

result = client.database_validation.validate(
    issuing_state="PER",
    services=["per_dni"],
    personal_number="11111111",
    vendor_data="user-1234",
)
print(result)
```

```javascript Node.js theme={null}
import Didit from "@didit-protocol/sdk-node";

	VendorData:     didit.String("user-1234"),
})
if err != nil {
	log.Fatal(err)
}
fmt.Printf("%+v\n", result)
```

```java Java theme={null}
import java.util.List;

// Reads DIDIT_API_KEY.
Didit client = new Didit();

        .issuingState("PER")
        .services(List.of("per_dni"))
        .personalNumber("11111111")
        .vendorData("user-1234")
        .build());

```

```php PHP theme={null}
<?php

require 'vendor/autoload.php';

use Didit\DiditClient;

// Reads DIDIT_API_KEY.
$didit = new DiditClient();

$result = $didit->databaseValidation->validate([
    'issuing_state' => 'PER',
    'services' => ['per_dni'],
    'personal_number' => '11111111',
    'vendor_data' => 'user-1234',
]);
print_r($result->toArray());
```

```ruby Ruby theme={null}
require "didit"

# Reads DIDIT_API_KEY.
didit = Didit::Client.new

result = didit.database_validation.validate(

  services: ["per_dni"],
  personal_number: "11111111",
  vendor_data: "user-1234"
)
puts result.to_h
```

```csharp .NET theme={null}
using System;

{
    IssuingState = "PER",
    Services = new string[] { "per_dni" },
    PersonalNumber = "11111111",
    VendorData = "user-1234",
});
Console.WriteLine(JsonSerializer.Serialize(result));
```

每次成功调用都会返回 HTTP `200`。**`outcome_code`** 字段说明实际发生的情况，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)可以覆盖该状态。

**`MATCH`** — 注册局确认了身份，且所有已检查字段均匹配。

```json 200 OK — MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "PER",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "per_dni",
      "service_name": "Peru - DNI verification",
      "source_data": {
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe",
        "maternal_name": "Doe Maternal",
        "paternal_name": "Doe Paternal",
        "verification_letter": "G",
        "verification_number": 2
      },
      "validation": {
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`NO_MATCH`** — 注册局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": "PER",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "per_dni",
      "service_name": "Peru - DNI verification",
      "source_data": {
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "identification_number": "no_match"
      }
    }
  ]
}
```

**`DOCUMENT_NOT_FOUND`** — 所提交的证件号码在注册局中没有对应记录。

```json 200 OK — DOCUMENT_NOT_FOUND theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "PER",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "DOCUMENT_NOT_FOUND",
      "service_id": "per_dni",
      "service_name": "Peru - DNI verification",
      "source_data": {
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "identification_number": "no_match"
      }
    }
  ]
}
```

## 返回数据

`source_data` 中实际返回的字段取决于注册局返回的内容。`per_dni` 的生成示例目前记录了以下标准化结构：

* `first_name`
* `identification_number`
* `last_name`
* `maternal_name`
* `paternal_name`
* `verification_letter`
* `verification_number`

## 定价与服务级别协议

秘鲁 DNI 验证查询仅在 Didit 从验证源收到确定结果时计费。

* **单次调用价格：** \$0.20 USD。
* **计费方式：** 按每次成功查询计费。若注册局无法访问、缺少必填字段，或请求在到达数据源之前被拒绝，则不收费。
* **延迟：** 典型 p95 \< 2 秒。
* **可用性：** Didit 方面每季度 99.9%；下游数据源的可用性因国家/地区和数据集而异。
