## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## What's an Apify Actor?

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

## npm Package Stats

Fetch npm package metadata, versions, dependencies, repository links, maintainers, and download counts from public npm registry APIs.

### What it does

For each npm package name you provide, this actor:

- Pulls the **full package metadata** from `https://registry.npmjs.org/<pkg>` (description, license, homepage, repository, keywords, maintainers, all published versions, latest version, dependency + devDependency counts on the latest manifest).
- Pulls the **download count** for a configurable period (last-day, last-week, last-month) from `https://api.npmjs.org/downloads/point/<period>/<pkg>`.
- Optionally includes the **N most recent versions** (version string + publish timestamp), sorted newest-first.

Both sources are keyless public APIs — no API key, no account, no captcha, no proxy required.

### Inputs

| Field | Type | Default | Notes |
|---|---|---|---|
| `packages` | array of strings | `["react", "lodash", "typescript"]` | Up to 200 per run. Bare package names. |
| `downloadPeriod` | enum | `"last-month"` | `last-day` / `last-week` / `last-month` |
| `includeVersions` | boolean | `false` | When true, include the N most recent versions. |
| `maxVersions` | integer (1-50) | `5` | Capped at 50. Ignored if `includeVersions=false`. |
| `includeDependencies` | boolean | `true` | When false, dependency counts are null (cheaper). |

### Output (one record per package)

```json
{
  "packageName": "react",
  "description": "React is a JavaScript library for building user interfaces.",
  "latestVersion": "19.2.7",
  "license": "MIT",
  "homepage": "https://react.dev/",
  "repositoryUrl": "https://github.com/facebook/react",
  "npmUrl": "https://www.npmjs.com/package/react",
  "downloads": 634528403,
  "downloadPeriod": "last-month",
  "maintainers": ["fb", "react-bot"],
  "keywords": ["react"],
  "dependenciesCount": 0,
  "devDependenciesCount": 0,
  "versionsCount": 2863,
  "recentVersions": null,
  "fetchedAt": "2026-07-10T07:28:52.038Z",
  "sourceUrls": [
    "https://registry.npmjs.org/react",
    "https://api.npmjs.org/downloads/point/last-month/react"
  ]
}
````

If a package fails to resolve (typo, withdrawn, network error), the actor pushes a per-package **error record** with `packageName`, `error`, `sourceUrl`, `downloadPeriod`, and `fetchedAt` so the failure is visible in the dataset without losing the rest of the run.

### Sources

- `https://registry.npmjs.org/<package>` — full package document (versions, maintainers, time, dist-tags, license, repository, keywords, etc.).
- `https://api.npmjs.org/downloads/point/<period>/<package>` — official npm downloads API.

Both endpoints are public. Be polite: the actor adds a small delay between requests to stay well under any reasonable rate limit.

### Local run

```bash
make install    # one-time
make run        # local test with .actor/input.json
make push       # build Docker image and push to Apify
make run-prod   # smoke test against the published build
```

# Actor input Schema

## `packages` (type: `array`):

List of npm package names to look up. Each name is the bare package slug (no version, no scope prefix).

## `downloadPeriod` (type: `string`):

Time window for the download count from the npm downloads API.

## `includeVersions` (type: `boolean`):

If true, include the most recent N version metadata entries (version + publish date).

## `maxVersions` (type: `integer`):

Maximum number of recent versions to include when includeVersions is true. Capped at 50.

## `includeDependencies` (type: `boolean`):

If true, count dependencies and devDependencies from the latest version manifest. If false, those fields are null (cheaper).

## Actor input object example

```json
{
  "packages": [
    "react",
    "lodash",
    "typescript"
  ],
  "downloadPeriod": "last-month",
  "includeVersions": false,
  "maxVersions": 5,
  "includeDependencies": true
}
