PyPI Package Scraper

Look up any Python package straight from PyPI's free, official JSON API. There is nothing to configure — no API key, no login, and no proxy — the data is public and rock-solid.

Give it a list of package names, pick how many you want, and get back one tidy JSON row per package — version, summary, author, license, dependencies, release count and download URLs included.

Features

• Looks up any package published on PyPI by name.
• Emits one flat, ready-to-use JSON record per package.
• Includes the full dependency list (requires_dist), project URLs and the number of published releases.
• Fetches packages concurrently in small batches to stay fast and polite.
• Skips gracefully over packages that don't exist — they are recorded with an error field so a single bad name never stops the run.

Input

Field	Type	Default	Description
packages	array	—	PyPI package names to look up, e.g. requests, flask.
maxItems	integer	50	Maximum number of packages to fetch.

Example input

{
  "packages": ["requests", "flask"],
  "maxItems": 50
}

Output

Each dataset record looks like this:

{
  "name": "requests",
  "version": "2.32.3",
  "summary": "Python HTTP for Humans.",
  "author": "Kenneth Reitz",
  "authorEmail": "me@kennethreitz.org",
  "license": "Apache-2.0",
  "homePage": "https://requests.readthedocs.io",
  "packageUrl": "https://pypi.org/project/requests/",
  "requiresPython": ">=3.8",
  "keywords": "",
  "dependencies": [
    "charset-normalizer<4,>=2",
    "idna<4,>=2.5",
    "urllib3<3,>=1.21.1",
    "certifi>=2017.4.17"
  ],
  "projectUrls": {
    "Homepage": "https://requests.readthedocs.io",
    "Source": "https://github.com/psf/requests"
  },
  "releaseCount": 158,
  "downloadUrls": [
    "https://files.pythonhosted.org/packages/.../requests-2.32.3-py3-none-any.whl"
  ]
}

Field	Description
name	Canonical package name.
version	Latest published version.
summary	One-line description.
author	Author name.
authorEmail	Author email.
license	License string.
homePage	Project home page URL.
packageUrl	Link to the package on PyPI.
requiresPython	Required Python version specifier.
keywords	Package keywords.
dependencies	Runtime dependencies (requires_dist), as an array of strings.
projectUrls	Map of labelled project links (docs, source, etc.).
releaseCount	Number of published releases.
downloadUrls	Download URLs for the latest release's files.

If a package can't be fetched (e.g. it doesn't exist), the row is { "name": "<name>", "error": "<message>" } instead.

Pricing

This actor uses the pay-per-event model: you are charged once per successfully scraped package (the package-scraped event). Packages that don't exist or can't be reached produce an error row and are never charged.

Data source

The actor talks to the official PyPI JSON API:

• Endpoint: https://pypi.org/pypi/<package>/json
• Returns info (metadata), releases (all versions) and urls (latest-release files).

The API is free and requires no authentication.
