# 在 Duaer 里检索靶点关联

在 Duaer 里用 Duaer Data 检索 Open Targets 基因–疾病关联。一次成功查询 1 额度。本页含完整英文调用技能。
## 能拿到什么

Duaer 数据市场里的「靶点关联」检索 Open Targets 基因–疾病关联分。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「靶点关联」，或打开 [数据市场](/zh/getting-started/data-market.md) 复制技能。基因符号见 [基因](/zh/getting-started/genes.md)；疾病名称见 [疾病](/zh/getting-started/diseases.md)。

## 在画布里检索

1. 打开节点创建器，点「Duaer 数据」，再选「靶点关联」。
2. Gene 或 Disease 至少填一项（新节点默认 Gene=INS）。Disease 可填名称或 EFO_/MONDO_ 编号；与 Gene 同填时过滤该基因关联。
3. Limit 默认 10，最大 20；结果按关联分降序。点执行此步骤。

成功扣 1 额度。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/targets?...
- Authorization: Bearer <Duaer key>
- 必须提供 gene 或 disease。

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 targets

Search Open Targets gene–disease associations through Duaer with a Duaer key.

## Call

`GET https://api.duaer.com/v1/data/targets?gene=INS&limit=10`

Header: `Authorization: Bearer <Duaer key>`

Use an account key or a model API key.

At least `gene` or `disease` is required.

- `gene` — gene symbol or Ensembl id. Look up symbols with https://skills.duaer.com/genes.md.
- `disease` — optional. Disease name or ontology id (`EFO_` / `MONDO_`). Alone, returns associated targets. With `gene`, filters that gene’s associations. Look up names with https://skills.duaer.com/diseases.md.
- `limit` — optional. From 1 to 20. Default 10. Results are sorted by association score descending.

## Result

Each item has `source`, `title`, `url`, `summary`, `gene`, `ensemblId`, `disease`, `diseaseId`, and `score`.
Reuse `gene` when searching proteins, genes, expression, interactions, or orthologs. Reuse `disease` when searching diseases or proteins.

## 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

### 只填疾病会怎样？

返回与该疾病关联最强的靶点基因列表，按关联分降序。
