在 Duaer 里检索蛋白结构

在 Duaer 里用 Duaer Data 检索蛋白结构。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「蛋白结构」按公开结构库检索。一次成功查询 1 额度。

从 Duaer 数据分类选「蛋白结构」，或在数据市场复制技能。

在画布里检索

打开节点创建器，点「Duaer 数据」，再选「蛋白结构」。
至少填一项：Words、PDB ID、Organism、Method、Resolution from/to、Released from/to、Polymer、Ligand。
Limit 默认 10，最大 20。点执行此步骤。

成功扣 1 额度。结果含 pdbId、method、resolution、organism、released、ligand 等。正式运行交付进数据池。

用 API 调用

GET https://api.duaer.com/v1/data/structures?...
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。下方是完整英文调用技能。

# Duaer structures

Search protein structures through Duaer with a Duaer key.

## Call

`GET https://api.duaer.com/v1/data/structures?q=insulin&organism=Homo%20sapiens&method=X-RAY%20DIFFRACTION&resolutionTo=2.5&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 structure record.
- `pdbId` — structure id, such as `4HHB`.
- `organism` — scientific name. Look up formal names with https://skills.duaer.com/organisms.md.
- `method` — experimental method, such as `X-RAY DIFFRACTION`, `SOLUTION NMR`, or `ELECTRON MICROSCOPY`.
- `resolutionFrom`, `resolutionTo` — resolution in angstroms. `0` means no bound.
- `releasedFrom`, `releasedTo` — release date as `YYYY-MM-DD`.
- `polymer` — `protein`, `dna`, or `rna`.
- `ligand` — bound chemical name.
- `limit` — optional. From 1 to 20. Default 10.

## Result

Each item has `source`, `title`, `url`, `summary`, `pdbId`, `method`, `resolution`, `organism`, `released`, and `ligand`.

## 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.
