# 在 Duaer 里检索关键词

在 Duaer 里用 Duaer Data 检索 UniProt 关键词。一次成功查询 1 额度。正式名可用于蛋白 Keyword。本页含完整英文调用技能。
## 能拿到什么

Duaer 数据市场里的「关键词」检索 UniProt 关键词。一次成功查询 1 额度。

从节点创建器的 [Duaer 数据分类](/zh/getting-started/duaer-data.md) 选「关键词」，或打开 [数据市场](/zh/getting-started/data-market.md) 复制技能。正式名可填进 [基因和蛋白](/zh/getting-started/proteins.md) 的 Keyword。

## 在画布里检索

1. 打开节点创建器，点「Duaer 数据」，再选「关键词」。
2. 用 Words 即可（新节点默认 kinase）。Keyword ID、Name 可选。
3. Limit 默认 10，最大 20。点执行此步骤。

成功扣 1 额度。把 title 用作蛋白 Keyword。正式运行的交付进 [数据池](/zh/getting-started/data-pool.md)。

## 用 API 调用

- GET https://api.duaer.com/v1/data/keywords?...
- Authorization: Bearer <Duaer key>
- 字段可组合；至少填一个检索字段。

密钥见 [Duaer 公开 API 的身份验证](/zh/api/authentication.md)。下方是与「复制技能」相同的英文技能。

## 调用技能（英文）

与数据市场「复制技能」一致。正文保持英文。

# Duaer keywords

Search UniProt keywords through Duaer with a Duaer key.

## Call

`GET https://api.duaer.com/v1/data/keywords?q=kinase&limit=10`

Header: `Authorization: Bearer <Duaer key>`

Use an account key or a model API key.

At least one search field is required. Fields combine.
Search with `q` first; use `id` only when you already have it from a result.

- `q` — words in the keyword name or definition.
- `id` — optional. UniProt keyword id from a result (`keywordId`), such as `KW-0418`.
- `name` — optional. Keyword name.
- `limit` — optional. From 1 to 20. Default 10.

## Result

Each item has `source`, `title`, `url`, `summary`, `keywordId`, `category`, `synonyms`, and `reviewedProteinCount`.
Use `title` as `keyword` when searching proteins. Reuse `keywordId` in `id` for an exact lookup.

## Credits

One successful search uses 1 credit.
An empty search, a failed search, a compound that matches nothing, or no remaining credits uses 0.
No remaining credits returns 402 and does not search.
A missing key returns 401.

```
## Questions

### 关键词用在哪里？
