# 在 Duaer 里检索基因

在 Duaer 里用 Duaer Data 检索基因。一次成功查询 1 额度。符号可用于蛋白 Gene。本页含完整英文调用技能。
## 能拿到什么

Duaer 数据市场里的「基因」检索公开基因库。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「基因」，或打开 [数据市场](/zh/getting-started/data-market.md) 复制技能。符号可填进 [基因和蛋白](/zh/getting-started/proteins.md) 的 Gene。

## 在画布里检索

1. 打开节点创建器，点「Duaer 数据」，再选「基因」。
2. 用 Words 即可（新节点默认 INS）。Symbol、Gene ID、Species 可选。
3. Limit 默认 10，最大 20。点执行此步骤。

成功扣 1 额度。把 symbol 用作蛋白 Gene。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/genes?...
- 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 genes

Search genes through Duaer with a Duaer key.

## Call

`GET https://api.duaer.com/v1/data/genes?q=INS&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` or `symbol` first; use `id` only when you already have an NCBI Gene id.

- `q` — words in the gene symbol, name, or summary.
- `symbol` — optional. Official gene symbol, such as `INS`.
- `id` — optional. NCBI Gene id from a result (`geneId`), such as `3630`.
- `species` — optional. Species for words/symbol search. Default `human`.
- `limit` — optional. From 1 to 20. Default 10.

## Result

Each item has `source`, `title`, `url`, `summary`, `geneId`, `symbol`, `name`, `aliases`, `ensemblId`, `taxId`, `mapLocation`, and `typeOfGene`.
Use `symbol` as `gene` when searching proteins. Reuse `geneId` 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

### 基因符号用在哪里？

把结果里的 symbol 填进 Duaer 基因和蛋白的 Gene 字段。
