## Parameters

| name | type | required | default | description |

| keyword | not declared | yes | not declared | 账号关键词：昵称、快手号或领域词，例如 美食；返回相关的快手账号和粉丝数、作品数。 |

## Response fields (items in `results`)

| field | meaning |
|---|---|
| next_page_token | 翻页令牌（comments、user_search）：作为下一次请求的 page_token 原样传回取下一页（其余参数不变，24 小时内有效）；同一页每行的值相同，响应顶层也有同一个 next_page_token。没有该字段即到底。 |
| user_id | 快手数字用户 ID（rank 类能力、user_search、user_live），可传 user_live 查直播状态。 |
| nickname | 昵称。 |
| kwai_id | 快手号（账号自己设的 ID，user_search）；没设时没有。 |
| bio | 个人简介，账号自己填写的文本。可能含换行和 emoji。 |
| gender | 性别（user_search）：M 男 / F 女。 |
| verified | 是否认证账号（user_search）。 |
| follower_count | 粉丝数（search、user_posts 是作者的；user_search 是这个账号的）。 |
| video_count | 累计作品数（search、user_posts 是作者的；user_live、user_search 是这个账号的）。 |
| avatar_url | 头像图片链接。部分平台给的是带尺寸参数的 CDN 链接，可能有时效。 |
| platform | 数据来源平台标识，与请求里的 platform 一致（如 xiaohongshu、tiktok）。 |
