# PyPI Package Metadata Scraper (`klondikeking/pypi-package-scraper`) Actor Extract detailed metadata for Python packages from the PyPI public API. Get version, dependencies, classifiers, license, author info, and release history for any PyPI package. - **URL**: https://apify.com/klondikeking/pypi-package-scraper.md - **Developed by:** [Pierrick McD0nald](https://apify.com/klondikeking) (community) - **Categories:** Developer tools, Automation - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing $1.00 / 1,000 package extracteds This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## PyPI Package Metadata Scraper — Extract Python Package Data from PyPI The PyPI Package Metadata Scraper extracts comprehensive metadata for any Python package hosted on the Python Package Index (PyPI). Using the official PyPI JSON API, this Actor retrieves version information, dependencies, classifiers, license details, author information, and release history in a structured format ready for analysis. ### Use Cases - **Dependency Analysis** — Audit the dependency trees and Python version requirements of packages in your stack - **License Compliance** — Batch-check licenses for all packages used in a project to ensure compliance - **Package Research** — Compare package maturity, release frequency, and maintainer activity across candidates - **Security Auditing** — Identify outdated packages and track release history for vulnerability assessment - **Market Intelligence** — Build datasets of Python ecosystem trends, popular frameworks, and emerging libraries ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `packageNames` | Array | Yes | List of PyPI package names to look up (e.g., requests, flask, django) | | `includeReleases` | Boolean | No | Include full release history with upload dates and file URLs (default: false) | | `proxyConfiguration` | Object | No | Proxy configuration for requests | ### Output The Actor outputs a dataset with the following fields for each package: ```json { "name": "requests", "version": "2.33.1", "summary": "Python HTTP for Humans.", "description": "## Requests...", "author": "Kenneth Reitz", "authorEmail": "me@kennethreitz.org", "maintainer": "Ian Stapleton Cordasco", "maintainerEmail": "graffatcolmingov@gmail.com", "license": "Apache-2.0", "homePage": "", "projectUrl": "https://pypi.org/project/requests/", "requiresPython": ">=3.10", "requiresDist": ["charset_normalizer<4,>=2", "idna<4,>=2.5", "urllib3<3,>=1.26"], "classifiers": ["Development Status :: 5 - Production/Stable", ...], "keywords": "", "platform": "", "uploadTime": "2026-03-30T16:09:15.531306Z", "releaseCount": 160, "latestReleaseUrl": "https://pypi.org/project/requests/2.33.1/", "sourceUrl": "https://github.com/psf/requests" } ```` ### Pricing Pay per event: **$0.001 USD per package extracted** ### Limitations - PyPI API returns 404 for packages that do not exist — these are logged as failed - Release history can be large for mature packages; use `includeReleases` sparingly for packages with 100+ releases - The PyPI JSON API does not provide download statistics (all download fields return -1) - Rate limiting is handled with automatic retries (3 attempts with backoff) ### FAQ **Q: Can I search for packages by keyword?** A: No — this Actor requires exact package names. Use `packageNames` with known PyPI package identifiers. **Q: Does this Actor require authentication?** A: No. The PyPI JSON API is public and requires no API key. **Q: What happens if a package is not found?** A: The Actor logs a warning, counts it as failed, and continues processing the remaining packages. ### Changelog - **v1.0.0** — Initial release # Actor input Schema ## `packageNames` (type: `array`): List of PyPI package names to look up (e.g., requests, flask, django) ## `includeReleases` (type: `boolean`): Include full release history with upload dates and file URLs ## `proxyConfiguration` (type: `object`): Proxy settings for the scraper ## Actor input object example ```json { "packageNames": [ "requests", "flask", "django", "numpy", "pandas" ], "includeReleases": false, "proxyConfiguration": { "useApifyProxy": true } } ``` # Actor output Schema ## `dataset` (type: `string`): No description ## `stats` (type: `string`): No description # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "packageNames": [ "requests", "flask", "django", "numpy", "pandas" ], "includeReleases": false, "proxyConfiguration": { "useApifyProxy": true } }; // Run the Actor and wait for it to finish const run = await client.actor("klondikeking/pypi-package-scraper").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
