API 文档 V2

批次名称、电子邮件和用户名预测

一批最多发送 50 个 GenderAPI v2 预测。了解每个项目的选项、保留的 ID、部分失败、响应摘要和信用会计。

批次名称、电子邮件和用户名

POST /gender/batch 接受 items 数组，其中包含 1-50 个具有 API 密钥访问权限的条目，或最多 10 个具有 IP 试用的条目。发送姓名、电子邮件地址、用户名或三者的混合。每个条目都有单独的 country、forceToGenderize 和 options 字段。 ID 是可选的，但在批次中必须是唯一的。

结果遵循输入顺序。每个结果包含 index、charged_credits 以及 data 或 error 中的一个。如果您提供了 id，它也会被退回。 HTTP 200 响应可能包含单个条目的失败，因此请检查每个结果。 meta.summary 包括 total、succeeded、identified、unknown 和 failed。在不知道性别的情况下完成的预测仍然算成功并需要花费积分。

如果请求验证或计划失败，则在扣除任何积分之前，整个批次都会被拒绝。如果所有条目在执行期间都失败，则 API 将返回带有 data 数组和旧别名 results 的非 2xx 问题响应。确认退款后，失败的条目将花费零积分。如果账单未经确认，请勿认为每个条目报告的费用都是最终的。

选择编程语言。 设置您的 API 密钥, 然后在您的服务器上运行该示例。

每个预测请求都是一个新的计费操作，包括重试。这些示例不会自动重试。在发送另一个请求之前检查计费状态。

运行之前：访问和错误处理

在您的服务器上运行这些示例。将流程环境中的 GENDERAPI_API_KEY 设置为现有的 API 密钥。确认 meta.access.mode 是 api_key：无法识别的密钥可以回退到 IP 试用。

对于 HTTP 4xx 和 5xx JSON 响应，示例保留错误正文并以非零状态退出。重试前请检查 code、action 和 meta.usage.billing_status。对于 HTTP 200 批量响应，还要检查每个结果中的 data 或 error。

计划批量积分和重试

使用现有的 Bearer API 密钥进行身份验证并发送 Content-Type: application/json。每个提交的批次都是一个新操作。如果重试部分失败，请在检查账单后仅提交失败的项目；重新发送成功的物品会再次向他们收费。

批量请求中的每一项默认使用 off，每个成功完成的预测消耗 1 积分。fallback 模式包含 AI 调用，总共也是 1 积分；always 模式消耗 2 积分。启用 forceToGenderize 时，数据集能够确定性别则消耗 1 积分，否则使用 AI，总共消耗 2 积分。成功完成但性别未知的预测也会扣除积分。初始余额为 1 积分即可开始批量请求，最终扣除后余额可以为负数。
