# 在 Duaer 里检索基因和蛋白

在 Duaer 里用 Duaer Data 检索基因和蛋白。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「基因和蛋白」按公开蛋白库检索。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「基因和蛋白」，或打开 [数据市场](/zh/getting-started/data-market.md) 复制技能。

## 在画布里检索

1. 打开节点创建器，点「Duaer 数据」，再选「基因和蛋白」。
2. 至少填一项：Words、Gene、Protein name、Organism、Accession、Reviewed、Length from/to、Disease、Keyword、Location、Function、Gene Ontology、Pathway、Taxonomy ID。正式病名见 [在 Duaer 里检索疾病](/zh/getting-started/diseases.md)。物种学名见 [在 Duaer 里检索物种](/zh/getting-started/organisms.md)。关键词见 [在 Duaer 里检索关键词](/zh/getting-started/keywords.md)；定位见 [在 Duaer 里检索亚细胞定位](/zh/getting-started/locations.md)；基因本体见 [在 Duaer 里检索基因本体](/zh/getting-started/gene-ontology.md)；通路见 [在 Duaer 里检索通路](/zh/getting-started/pathways.md)。
3. Limit 默认 10，最大 20。点执行此步骤。

成功扣 1 额度。结果含 source、title、url、summary，以及 accession、gene、organism、length、reviewed、disease、location。正式运行的交付节点条目进 [数据池](/zh/getting-started/data-pool.md)。

## 用 API 调用

- GET https://api.duaer.com/v1/data/proteins?...
- 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 proteins

Search genes and proteins through Duaer with a Duaer key.

## Call

`GET https://api.duaer.com/v1/data/proteins?gene=INS&organism=Homo%20sapiens&reviewed=yes&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.

- `q` — words in the protein record.
- `gene` — gene symbol.
- `name` — protein name.
- `organism` — organism name. Look up formal names with https://skills.duaer.com/organisms.md.
- `accession` — accession.
- `reviewed` — `yes` or `no`.
- `lengthFrom`, `lengthTo` — sequence length. `0` means no bound.
- `disease` — disease name. Look up formal names with https://skills.duaer.com/diseases.md.
- `keyword` — UniProt keyword. Look up formal names with https://skills.duaer.com/keywords.md.
- `location` — subcellular location. Look up formal names with https://skills.duaer.com/locations.md.
- `function` — words in the function text.
- `go` — Gene Ontology term. Look up terms with https://skills.duaer.com/gene-ontology.md.
- `pathway` — Reactome pathway id or words. Look up pathways with https://skills.duaer.com/pathways.md.
- `taxonomyId` — NCBI taxonomy id. Look up ids with https://skills.duaer.com/organisms.md.
- `limit` — optional. From 1 to 20. Default 10.

## Result

Each item has `source`, `title`, `url`, `summary`, `accession`, `gene`, `organism`, `length`, `reviewed`, `disease`, and `location`.

## 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.
