## 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.

# README

## npm Package Data — Registry Info & Download Stats to JSON

**Get clean data for any npm package — as JSON.** Pass package names and get back a tidy row per package: latest version, description, license, repository, author, keywords, dependency count, publish dates and download counts. Powered by the official npm registry — no API key, no anti-bot.

> AI-agent ready: this Actor is callable and payable by AI agents via [x402](https://docs.apify.com/platform/integrations/x402) (USDC on Base), no Apify account required.

Skip scraping npmjs.com — pull structured package data for dashboards, research and supply-chain analysis in one run.

### Who uses this

- 🧑‍💻 **Developers & OSS maintainers** — inventory and compare packages.
- 📊 **Analysts & researchers** — study download trends, licenses and dependencies at scale.
- 🔐 **Security & supply-chain teams** — audit dependencies, licenses and maintainers.
- 🤖 **Data & AI pipelines** — feed clean package metadata into your tooling.
- 📈 **DevRel & competitive intel** — track a package's popularity over time.

### What you get — one clean row per package

| Field | Description |
|---|---|
| `name` + `latestVersion` | Package & current version |
| `description` | Package description |
| `license` | License (e.g. MIT) |
| `repository` + `homepage` | Source & site links |
| `author` + `maintainersCount` | Author & maintainers |
| `keywords` | Package keywords |
| `dependenciesCount` + `dependencies` | Dependencies |
| `versionsCount` | Number of published versions |
| `created` + `lastPublish` | First & last publish dates |
| `downloads` + `downloadsPeriodLabel` | Download counts (optional period) |
| `npmUrl` | Link to the npm page |

### Example

**Input**
```json
{ "packages": ["react", "express", "lodash"], "downloadsPeriod": "last-month" }
````

**Output (one item)**

```json
{
  "name": "react", "latestVersion": "19.1.0",
  "description": "React is a JavaScript library for building user interfaces.",
  "license": "MIT", "author": "Meta",
  "dependenciesCount": 1, "versionsCount": 2200,
  "lastPublish": "2026-06-20T12:00:00Z",
  "downloads": 24500000, "downloadsPeriodLabel": "last-month",
  "npmUrl": "https://www.npmjs.com/package/react"
}
```

### Why this actor

- ✅ **Official source** — the npm registry, always current.
- 📦 **Rich metadata** — version, license, deps, maintainers, dates.
- 📈 **Optional download stats** — add a period to fetch download counts.
- ⚡ **Fast & affordable** — pay only per package returned. No key, no anti-bot.
- 🧹 **Clean output** — normalized JSON, ready for Sheets/Excel/your database.

### Input options

- `packages` *(required)* — npm package names.
- `downloadsPeriod` — optional download window (e.g. `last-week`, `last-month`).

### FAQ

**Do I get download counts?** Optionally — set `downloadsPeriod` to include them (adds a call per package).

**Which data is included?** Version, description, license, repository, author, keywords, dependency and version counts, and publish dates.

**How fresh is the data?** Live from the npm registry on every run.

**Can I query many packages at once?** Yes — pass a list; every row carries its own package name.

**Can I export to CSV/Excel/Google Sheets?** Yes — the dataset exports to JSON, CSV, Excel and HTML, or pull it via the API.

**What does it cost?** Pay-per-package — you're only charged for packages actually returned.

***

*Tip: track your dependencies weekly and diff `latestVersion`/`downloads` to monitor updates and momentum.*
