# 在 Duaer 里查PyPI 软件包

在 Duaer 里：查询 PyPI 上某个 Python 软件包的最新版本、许可证、支持的 Python 版本、链接与已知漏洞数。一次成功查询用 1 额度。
## 能拿到什么

Duaer 数据市场里的「PyPI 软件包」：查询 PyPI 上某个 Python 软件包的最新版本、许可证、支持的 Python 版本、链接与已知漏洞数。查到结果时用 1 额度，结果交给数字组织的下一个节点。

从节点创建器选 Duaer 数据 → PyPI 软件包，或打开 [数据市场](/zh/getting-started/data-market.md)。相关：[OSV 开源漏洞](/zh/getting-started/osv.md)、[npm 软件包](/zh/getting-started/npm.md)。

## 适合做什么

- 查某 Python 包的最新版本与所需 Python 版本。
- 确认包名是否存在及其许可证。

## 在画布里检索

1. 打开节点创建器，选 Duaer 数据 → PyPI package。
2. 填 Package（如 requests）。
3. Limit 默认 10，最大 20。执行。

查到结果才扣 1 额度；没有结果、输入有误或上游失败都不扣。

## 用 API 调用

- GET https://api.duaer.com/v1/data/pypi?package=requests
- Authorization: Bearer <Duaer key>

# Duaer PyPI package

Duaer PyPI package reads one project from the Python Package Index by its exact name.

## When to use

- Check the latest version and Python support of a dependency.
- See whether PyPI lists known vulnerabilities for the latest release.

## When not to use

- Searching by keyword. Use https://skills.duaer.com/npm.md for JavaScript; PyPI has no search API.
- Vulnerabilities in older versions. Use https://skills.duaer.com/osv.md.

## Call

`GET https://api.duaer.com/v1/data/pypi?package=requests`

Header: `Authorization: Bearer <Duaer key>`

Use an account key or a model API key.

Get a Duaer key: https://skills.duaer.com/keys.md

## Parameters

Provide `package`.

- `package` — Exact package name, such as requests or numpy.

## Examples

- `GET https://api.duaer.com/v1/data/pypi?package=requests` — the requests package.
- `GET https://api.duaer.com/v1/data/pypi?package=numpy` — the numpy package.

## Result

The response is `{ "items": [...] }`. Each item has `source`, `title`, `url`, and `summary`, plus:

- `package`, `version`, `description`, `license` — package facts.
- `requiresPython`, `dependencies` — Python range and number of declared dependencies.
- `author`, `homepage`, `documentation` — people and links.
- `knownVulnerabilities`, `released` — vulnerabilities PyPI lists for this release, and its upload time.

The search returns one row, or none when the name does not exist.

Fields without a value are left out.

## Credits

A search that returns at least one row uses 1 credit.
An empty search, a search that finds nothing, or a failed search uses 0.
Wrong input returns 400 with a message and uses 0.
No remaining credits returns 402 and does not search.
A missing key returns 401.
