# 蒲公英关键词概览（搜索指数+博主画像）/PGY keyword overview

`POST /api/v1/xiaohongshu/pgy/get_keyword_stat`

## 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_keyword_stat`
- Auth: HTTP bearer

# [中文]
### 用途:
- 给定一个关键词，返回它在小红书全站的热度概览，以及发这个词的博主长什么样
- 对应蒲公英内容广场搜索后的「全站数据」+「合作博主画像」两张卡片
### 请求体参数:
- search_word: 关键词，如 "面膜"
### 返回:
| 对象 | 字段 |
|---|---|
| `searchWordData` | `searchScore` 搜索指数、`noteNum` 关联笔记数、`userNum` 搜索人数、`readNum` 阅读量；每项都有对应的 `*30bm` 字段，是近 30 日环比百分比 |
| `wordKolProfile` | 合作博主画像：内容类目占比（如 护肤 93.8%）、账号人设占比（如 妈妈 25%） |
### 配套接口:
- 同一个关键词还可以调 `/get_keyword_daily` 看逐日走势、`/get_keyword_related` 看上下游关联词
- 三个接口互相独立，按需调用

### 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:
- Site-wide popularity overview of a keyword, plus the profile of bloggers posting about it
- Corresponds to the "Site Data" + "Blogger Profile" cards in the PGY content square
### Request Body Parameters:
- search_word: keyword, e.g. "面膜"
### Return:
| Object | Fields |
|---|---|
| `searchWordData` | `searchScore`, `noteNum`, `userNum`, `readNum`; each has a `*30bm` counterpart = 30-day change in percent |
| `wordKolProfile` | Blogger profile: content category share, persona share |
### Related:
- `/get_keyword_daily` for the daily trend, `/get_keyword_related` for up/downstream keywords
- The three endpoints are independent; call whichever you need

### 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
{"search_word": "面膜"}
```

**选题流程**：`/get_keyword_related` 扩出一批词 → 逐个调本接口比 `searchScore`
与 `noteNum` → 挑「搜索量不低但笔记数少」的词，即竞争小的机会词。

同一个关键词还可以调 `/get_keyword_daily` 看逐日走势。三个接口互相独立，按需调用。

Workflow: expand words via `/get_keyword_related`, compare `searchScore` vs `noteNum` here,
pick high-search / low-supply keywords.

## Request body

- KeywordReq
  - `search_word` string, required: 关键词，如 面膜/Keyword
