# 哥伦比亚 Cédula 核验 API：身份信息查询

> Didit 提供哥伦比亚 Cédula 权威数据库查询，基于其身份基础设施，按次计费，单次低至 $0.20，无合同、无最低消费。

根据 Registraduría General de la Nación / ANI 政府记录，核验哥伦比亚公民的身份数据。Didit 通过 `POST /v3/database-validation/` 提供此服务，以便您将提交的数据与权威数据源进行比对，并获得标准化的匹配结果。输入格式：`personal_number` 接受哥伦比亚身份证号（Cédula，6-10 位数字）。

## 覆盖范围

* **覆盖率：** 90-95%
* **国家/地区：** Colombia
* **服务 ID：** `col_cedula`
* **数据领域：** 身份
* **类别：** NationalIDRegistry

## 输入

| 字段 | 必填 | 示例 |
| - | -: | - |
| `personal_number` | 是 | `111111` |
| `date_of_issue` | 是 | `1990-01-01` |
| `first_name` | 否 | `John` |
| `last_name` | 否 | `Doe` |
| `vendor_data` | 否 | `user-1234` |

* **必填输入：** `personal_number`、`date_of_issue`
* **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
* **覆盖率：** 90-95%
* **价格：** 每次成功查询 \$0.20

## 请求体参数

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

此数据库服务所使用的 ISO 3166-1 alpha-3 国家代码。

示例：`COL`

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

包含此服务 ID 的数组。固定服务 ID 可将请求限定在此特定数据库范围内。

示例：`col_cedula`

**personal\_number** `string` *required* (default: 111111)

特定国家的个人身份编号。

示例：`111111`

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

此数据库服务所需的 `date_of_issue` 值。

示例：`1990-01-01`

**first\_name** `string`

待核验的名字。

示例：`John`

**last\_name** `string`

待核验的姓氏。

示例：`Doe`

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

您为该用户设置的稳定用户标识，例如您内部的用户 ID。Didit 使用它将独立核验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

* 哥伦比亚身份证号（Cédula，6-10 位数字）
* `personal_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。
* `personal_number` 长度必须为 6-10 个字符。

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` 为默认功能状态；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)可以覆盖它。

**`MATCH`**：登记机构已确认该身份，且所有核验字段均匹配。

```json 200 OK — MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "COL",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "col_cedula",
      "service_name": "Colombia - Cédula verification",
      "source_data": {
        "cedula_status": "sample_value",
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe",
        "verifications": {
          "identification_number": true
        }
      },
      "validation": {
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`PARTIAL_MATCH`**：此服务比对的一个或多个字段未完全匹配。在本示例中，`identification_number` 不匹配。

```json 200 OK — PARTIAL_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "COL",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "col_cedula",
      "service_name": "Colombia - Cédula verification",
      "source_data": {
        "cedula_status": "sample_value",
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe",
        "verifications": {
          "identification_number": false
        }
      },
      "validation": {
        "identification_number": "no_match"
      }
    }
  ]
}
```

**`NO_MATCH`**：登记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": "COL",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "col_cedula",
      "service_name": "Colombia - Cédula verification",
      "source_data": {
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "identification_number": "no_match"
      }
    }
  ]
}
```

**`INCONCLUSIVE`**：登记机构无法判断该人员是否匹配，结果确实不确定（其可能在登记机构中，也可能不在其中）。这不是无匹配结果，也不是技术性图像问题；没有任何字段被确认，因此 match\_type 为 null，该核验将送入人工审核。

```json 200 OK — INCONCLUSIVE theme={null}
{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "COL",
  "match_type": null,
  "validations": [
    {
      "outcome_code": "INCONCLUSIVE",
      "service_id": "col_cedula",
      "service_name": "Colombia - Cédula verification",
      "source_data": {},
      "validation": {}
    }
  ]
}
```

**`DOCUMENT_NOT_FOUND`**：提交的证件号码在登记机构中没有对应的任何记录。

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

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

## 定价与服务等级

哥伦比亚：Cédula 核验查询仅在 Didit 从核验数据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。若登记机构无法访问、缺少必填字段，或请求在到达数据源之前即被拒绝，则不收费。
* **延迟：** 典型 p95 延迟 \< 2 秒。
* **可用性：** Didit 一侧的可用性为每季度 99.9%；下游数据源的可用性因国家和数据集而异。
