在 Duaer 里检索表达

在 Duaer 里用 Duaer Data 检索 GTEx 组织中位表达。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「表达」检索 GTEx 各组织中位 TPM。一次成功查询 1 额度。

从节点创建器的 Duaer 数据分类选「表达」，或打开数据市场复制技能。基因符号见基因；蛋白见基因和蛋白；基因–疾病关联见靶点关联。

在画布里检索

打开节点创建器，点「Duaer 数据」，再选「表达」。
Gene 或 Gencode ID 至少填一项（新节点默认 Gene=INS）。Tissue 可选（如 Pancreas）。
Limit 默认 10，最大 20；结果按中位 TPM 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。

用 API 调用

GET https://api.duaer.com/v1/data/expression?...
Authorization: Bearer <Duaer key>
必须提供 gene 或 gencodeId。

密钥见 Duaer 公开 API 的身份验证。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 expression

Search GTEx median tissue expression through Duaer with a Duaer key.

## Call

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

Header: `Authorization: Bearer <Duaer key>`

Use an account key or a model API key.

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

- `gene` — gene symbol. Look up symbols with https://skills.duaer.com/genes.md.
- `gencodeId` — optional. Ensembl/Gencode id from a result, such as `ENSG00000254647.6`.
- `tissue` — optional. GTEx tissue id, such as `Pancreas` or `Adipose_Subcutaneous`.
- `limit` — optional. From 1 to 20. Default 10. Results are sorted by median TPM descending.

## Result

Each item has `source`, `title`, `url`, `summary`, `gene`, `gencodeId`, `tissue`, `tissueLabel`, `median`, `unit`, `ontologyId`, and `dataset`.
Reuse `gene` when searching proteins or genes. Reuse `gencodeId` in `gencodeId` for an exact expression lookup. For gene–disease associations, use https://skills.duaer.com/targets.md.

## Credits

One successful search uses 1 credit.
An empty search, a failed search, a compound that matches nothing, or no remaining credits uses 0.
