## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## PyPI Package Scraper

Look up any Python package straight from **[PyPI](https://pypi.org/)**'s **free, official [JSON API](https://docs.pypi.org/api/json/)**. 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

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

### Output

Each dataset record looks like this:

```json
{
  "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.

# 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';

const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "maxItems": 50
};

// Run the Actor and wait for it to finish
const run = await client.actor("receptional_blender/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();
