# 哥斯达黎加 Cédula 验证 API：数据匹配

> 哥斯达黎加 Cédula 验证：通过 Didit 查询哥斯达黎加权威数据库。按次付费，起价 $0.20，无合同，无最低消费。

根据 Tribunal Supremo de Elecciones 的政府记录核验哥斯达黎加国民身份证信息。Didit 通过 `POST /v3/database-validation/` 提供此服务，便于您将提交的数据与权威来源进行比对，并获得标准化的匹配结果。输入格式：`personal_number` 填写哥斯达黎加 Cédula（9-12 位数字）。

## 覆盖范围

* **覆盖范围：** 90-95%
* **国家/地区：** 哥斯达黎加
* **服务 ID：** `cri_cedula`
* **数据域：** 身份
* **类别：** NationalIDRegistry

## 输入

| 字段 | 必填 | 示例 |
| - | -: | - |
| `personal_number` | 是 | `111111111` |
| `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：** 无需
* **工作流可用性：** 可在工作流中使用
* **覆盖范围：** 90-95%
* **价格：** 每次成功查询 \$0.20

## 请求体参数

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

此数据库服务的 ISO 3166-1 alpha-3 国家代码。

示例：`CRI`

**services** `string` *required* (default: cri\_cedula)

包含此服务 ID 的数组。指定该服务可将请求限定为仅使用此特定数据库。

示例：`cri_cedula`

**personal\_number** `string` *required* (default: 111111111)

特定国家的个人身份号码。

示例：`111111111`

**first\_name** `string`

待验证的名字。

示例：`John`

**last\_name** `string`

待验证的姓氏。

示例：`Doe`

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

您为该用户提供的稳定用户标识，例如您内部的用户 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`

## 输入规则与验证说明

* 哥斯达黎加 Cédula（9-12 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` 长度必须为 9-12 个字符。

})
if err != nil {
	log.Fatal(err)
}
fmt.Printf("%+v\n", result)

    PersonalNumber = "111111111",
    VendorData = "user-1234",
});
Console.WriteLine(JsonSerializer.Serialize(result));
```

每次成功调用都返回 HTTP `200`。**`outcome_code`** 字段说明实际发生的情况，例如能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`）。显示的 `status` 是默认功能状态；您配置的[部分匹配/未匹配操作](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": "CRI",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "cri_cedula",
      "service_name": "Costa Rica - Cédula verification",
      "source_data": {
        "first_name": "John",
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe"
      },
      "validation": {
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`NO_MATCH`** — 注册机构未返回与提交数据匹配的记录。

```json 200 OK — NO_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "CRI",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "cri_cedula",
      "service_name": "Costa Rica - Cédula verification",
      "source_data": {
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "identification_number": "no_match"
      }
    }
  ]
}
```

**`DOCUMENT_NOT_FOUND`** — 提交的证件号码与注册机构中的任何记录都不对应。

```json 200 OK — DOCUMENT_NOT_FOUND theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "CRI",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "DOCUMENT_NOT_FOUND",
      "service_id": "cri_cedula",
      "service_name": "Costa Rica - Cédula 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机构返回的内容。`cri_cedula` 的生成示例目前记录了以下标准化结构：

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

## 定价与 SLA

哥斯达黎加 - Cédula 验证查询仅在 Didit 从验证来源收到明确结果时计费。

* **单次调用价格：** \$0.20 USD。
* **计费：** 按每次成功查询计费。以下情况不收费：注册机构无法访问、缺少必填字段，或请求在到达数据来源前即被拒绝。
* **延迟：** 典型 p95 小于 2 秒。
* **可用性：** Didit 一侧每季度 99.9%；下游数据源的可用性因国家和数据集而异。
