发送请求之前 将 JSON 发送到 POST https://api.genderapi.io/api/v2/gender 。请在 Authorization: Bearer YOUR_API_KEY 中使用您现有的 API 密钥,并发送 Content-Type : application/json。每个请求都会被独立处理。
在代码示例中选择编程语言。运行前,请在进程环境中设置 GENDERAPI_API_KEY 。缺失或无法识别的密钥可能会使用共享的 IP 试用,因此集成账户时请确认 meta.access.mode 为 api_key 。
根据电子邮箱地址判断性别 使用 type : email 。API 会在地址中查找可用的姓名信号。共享邮箱和含义不明的本地部分可能返回未知结果。这里同样可以选择使用 forceToGenderize ;即使没有真实名字,它也允许 AI 根据别名进行推断。
选择编程语言。 设置您的 API 密钥 ,然后在您的服务器上运行示例。
每个预测请求(包括重试)都是一次新的计费操作。这些示例不会自动重试。发送下一个请求之前,请先检查计费状态。
运行之前:访问与错误处理 请在您的服务器上运行这些示例。在进程环境中将 GENDERAPI_API_KEY 设置为您现有的 API 密钥。请确认 meta.access.mode 为 api_key :无法识别的密钥可能会转为使用 IP 试用。
对于 HTTP 4xx 和 5xx JSON 响应,示例会保留错误响应体并以非零状态退出。重试前请检查 code 、action 和 meta.usage.billing_status 。

} 电子邮箱地址验证与姓名信号 value 必须是语法有效的电子邮箱地址。语法无效时,会在计费前返回 HTTP 422。语法验证并不能证明该邮箱存在,也不能证明它属于某个特定的人。
地址中可识别的个人姓名可能与数据集匹配。共享邮箱、职能地址和含义不明的本地部分可能返回 gender: null 。默认情况下,无法确定的单个查询会使用普通的 AI 回退,总共消耗 1 个积分,成功完成的未知结果也同样计费。
如果希望在数据集无法确定时使用可识别昵称的 AI 推断,请设置 forceToGenderize : true 。数据集得出结果时消耗 1 个积分,使用 AI 时总共消耗 2 个积分。API 仍可能返回 null 。电子邮箱域名并不能证明此人所在的位置;只有在掌握相关背景时才提供国家/地区。
