# 巴西死亡核查（CPF）API：实时身份查询

> Didit 提供巴西死亡核查（CPF）：通过权威的巴西数据库核验身份。按次计费，单次调用低至 $0.20，无合约、无最低消费。

检查 CPF 持有人是否被登记为已故，并将持有人的姓名和出生日期与 Receita Federal 的记录进行比对。Didit 通过 `POST /v3/database-validation/` 提供此服务，使您能够将提交的数据与权威来源进行核验，并获得标准化的匹配结果。

## 请求体参数

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

此数据库服务的 ISO 3166-1 alpha-3 国家/地区代码。

示例：`BRA`

**services** `string` *required* (default: bra\_death\_check)

包含此服务 ID 的数组。指定该服务可使请求仅限定于此确切数据库。

示例：`bra_death_check`

**tax\_number** `string` *required* (default: 12345678909)

税务或财政识别号码。

示例：`12345678909`

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

需要核验的名字。

示例：`John`

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

需要核验的姓氏。

示例：`Doe`

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

采用 `YYYY-MM-DD` 格式的出生日期。

示例：`1990-01-01`

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

您为此人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

* 巴西 CPF（恰好 11 位数字）
* `tax_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。
* `tax_number` 的长度必须恰好为 11 个字符。
* `tax_number` 必须匹配 `\d{3}\.?\d{3}\.?\d{3}-?\d{2}`。

每次成功调用都返回 HTTP `200`。**`outcome_code`** 字段说明实际发生的情况，例如能够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` 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)可以覆盖它。

**`MATCH`**：登记机构确认了身份，且所有核对字段均匹配。

```json 200 OK — MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "BRA",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "bra_death_check",
      "service_name": "Brazil - Death Check (CPF)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "first_name": "JOHN",
        "full_name": "JOHN DOE",
        "identification_number": "12345678909",
        "is_deceased": false,
        "last_name": "DOE",
        "tax_id_status": "REGULAR"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "full_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`PARTIAL_MATCH`**：找到了证件号码，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": "BRA",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "bra_death_check",
      "service_name": "Brazil - Death Check (CPF)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "first_name": "JOHN",
        "full_name": "JOHN DOE",
        "identification_number": "12345678909",
        "is_deceased": false,
        "last_name": "DOE",
        "tax_id_status": "REGULAR"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "no_match",
        "identification_number": "full_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": "BRA",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "bra_death_check",
      "service_name": "Brazil - Death Check (CPF)",
      "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"
      }
    }
  ]
}
```

**`DOCUMENT_NOT_FOUND`**：提交的证件号码与登记库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": "BRA",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "DOCUMENT_NOT_FOUND",
      "service_id": "bra_death_check",
      "service_name": "Brazil - Death Check (CPF)",
      "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，但登记机构将该人员标记为已故。

```json 200 OK — DECEASED theme={null}
{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "BRA",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "DECEASED",
      "service_id": "bra_death_check",
      "service_name": "Brazil - Death Check (CPF)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "death_year": 2021,
        "first_name": "JOHN",
        "full_name": "JOHN DOE",
        "identification_number": "12345678909",
        "is_deceased": true,
        "last_name": "DOE",
        "tax_id_status": "TITULAR FALECIDO"
      },
      "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机构返回的内容。`bra_death_check` 的自动生成示例目前记录了以下标准化结构：

* `date_of_birth`
* `death_year`
* `first_name`
* `full_name`
* `identification_number`
* `is_deceased`
* `last_name`
* `tax_id_status`

## 定价与服务等级协议

巴西 - 死亡核查（CPF）查询仅在 Didit 从核验来源收到明确结果时计费。

* **单次调用价格：** 每次 \$0.20 美元。
* **计费方式：** 按每次成功的查询计费。登记机构无法访问、必填字段缺失，或请求在到达来源前即被拒绝时，不收取费用。
* **延迟：** 典型 p95 延迟 \< 2 秒。
* **可用性：** Didit 方每季度 99.9%；下游来源的可用性因国家/地区和数据集而异。
