# 在 Duaer 里检索互作

在 Duaer 里用 Duaer Data 检索 STRING 蛋白互作伙伴。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「互作」检索 STRING 蛋白互作伙伴。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「互作」，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)；蛋白见 [基因和蛋白](/zh/getting-started/proteins.md)；物种 Taxonomy ID 见 [物种](/zh/getting-started/organisms.md)。

## 在画布里检索

1. 打开节点创建器，点「Duaer 数据」，再选「互作」。
2. Protein 必填（新节点默认 INS）。Species 默认 9606；Required score 可选（0–1000）。
3. Limit 默认 10，最大 20。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/interactions?...
- Authorization: Bearer <Duaer key>
- 必须提供 protein。

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 interactions

Search STRING protein interaction partners through Duaer with a Duaer key.

## Call

`GET https://api.duaer.com/v1/data/interactions?protein=INS&species=9606&limit=10`

Header: `Authorization: Bearer <Duaer key>`

Use an account key or a model API key.

`protein` is required. Other fields are optional.

- `protein` — gene symbol, UniProt accession, or STRING id. Look up symbols with https://skills.duaer.com/genes.md or proteins with https://skills.duaer.com/proteins.md.
- `species` — optional. NCBI taxonomy id. Default `9606` (human). Look up ids with https://skills.duaer.com/organisms.md.
- `requiredScore` — optional. STRING threshold from 0 to 1000. Omit for the STRING default.
- `limit` — optional. From 1 to 20. Default 10.

## Result

Each item has `source`, `title`, `url`, `summary`, `proteinA`, `proteinB`, `stringIdA`, `stringIdB`, `partner`, `partnerStringId`, `score`, `neighborhood`, `fusion`, `cooccurrence`, `coexpression`, `experimental`, `database`, `textmining`, and `taxId`.
Reuse `partner` as `gene` when searching proteins, or as `protein` for further interaction partners.

## 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

### partner 字段是什么？

相对查询蛋白的互作伙伴基因符号；可用它再查蛋白或继续查互作。
