# 获取蒲公英相似博主推荐/Get PGY similar bloggers

`POST /api/v1/xiaohongshu/pgy/get_blogger_similar`

## Request

- Base URL: `https://api.tikhub.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.tikhub.io/api/v1/xiaohongshu/pgy/get_blogger_similar`
- Auth: HTTP bearer

# [中文]
### 用途:
- 给定一个博主，返回平台判定与其相似的其它博主，对应博主主页下方「相似博主推荐」
- 典型用法：先选出一个满意的标杆博主，再用本接口按相似度扩量选号
### 请求体参数:
- user_id: **必填**，目标博主用户ID
- page_num: 页码，从 1 开始
- page_size: 每页数量，**1-4**（蒲公英网页固定 4，不能更大）
### 返回:
- 结构与「笔记博主广场」完全一致 —— 同样的 kols[] + total，可直接复用解析代码
- 相似博主总数通常只有个位数到几十，total 即为上限
### 翻页:
- 只改 page_num，user_id 保持不变；翻到返回空数组即没有更多

### 响应结构（取数要剥两层）:
- `resp["data"]` 是蒲公英原样信封（含 `code`/`msg`/`success`），业务数据还在它里面一层
- 正确取法：`data = resp["data"]["data"]`；下面「返回」列的字段都在这一层下
### 计费:
- HTTP 200 → **计费**。包含「查无结果」（`data` 为 null，如 ID 不存在或筛选无命中）——
  请求已送达蒲公英，同样扣费，不要因为拿不到数据就重试
- HTTP 400 → 不计费（参数格式非法，或上游资源不足/异常）

# [English]
### Purpose:
- Given one blogger, return similar bloggers ("Similar Bloggers" on the blogger page)
- Typical use: pick one good benchmark blogger, then expand by similarity
### Request Body Parameters:
- user_id: **required**, target blogger user ID
- page_num: page number from 1
- page_size: **1-4** (fixed at 4 on the PGY web page)
### Return:
- Same shape as the note blogger square (kols[] + total), parsing code is reusable
- Similar bloggers usually number from a few to a few dozen; total is the cap
### Paging:
- Change page_num only; an empty array means no more data

### Response shape (two layers):
- `resp["data"]` is PGY's raw envelope (with `code`/`msg`/`success`); the payload is one level deeper
- Correct access: `data = resp["data"]["data"]` — every field listed under "Return" lives here
### Billing:
- HTTP 200 → **charged**, including "no result" (`data` is null, e.g. ID not found or filters matched
  nothing): the request did reach PGY, so retrying on empty data just burns quota
- HTTP 400 → not charged (malformed params, or upstream unavailable/error)

# [示例/Example]
```json
// ① 第一页（每页最多 4 个，这是蒲公英网页的固定值）
{"user_id": "5c668b3e0000000012021605", "page_num": 1, "page_size": 4}

// ② 翻页：只改 page_num
{"user_id": "5c668b3e0000000012021605", "page_num": 2, "page_size": 4}
```

**想「找相似 + 再按粉丝量/报价筛一遍」**，用 `/get_blogger_list` 的 `similar_user_id`
参数 —— 那条链路支持叠加全部筛选；本接口只按相似度返回、不支持筛选。

To combine similarity with other filters, use `similar_user_id` on `/get_blogger_list` instead.

## Request body
