## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## npm Package Scraper — Search, Stats & Dependencies

Scrape the npm registry for package data, download statistics, dependency analysis, and more. Uses the official npm API — no browser needed, blazing fast and cost-effective.

### Features

#### 🔍 Search Mode

Search for packages by keyword. Get names, versions, descriptions, download counts, scores, and more.

#### 📦 Package Details Mode

Get comprehensive details for specific packages: versions, maintainers, dependencies, creation dates, TypeScript support, and optionally README content.

#### 📊 Download Stats Mode

Get download statistics with daily breakdowns. Supports periods: last-day, last-week, last-month, last-year. Includes averages, min/max calculations.

#### 🏆 Popular Mode

Discover the most popular npm packages across categories, sorted by download count.

#### 🔗 Dependencies Mode

Analyze dependency trees: production deps, dev deps, peer deps with version requirements.

### Use Cases

- **Market Research**: Find trending packages in any niche
- **Dependency Auditing**: Analyze what your projects depend on
- **Tech Stack Analysis**: Track which tools and frameworks are growing
- **Competitor Research**: Compare package popularity and maintenance
- **Security Auditing**: Map dependency trees for vulnerability assessment

### Output Example

```json
{
  "name": "express",
  "version": "4.21.0",
  "description": "Fast, unopinionated, minimalist web framework",
  "weeklyDownloads": 35000000,
  "monthlyDownloads": 140000000,
  "license": "MIT",
  "homepage": "http://expressjs.com/",
  "repository": "https://github.com/expressjs/express"
}
```

### Cost

This actor uses only HTTP requests to the npm API — no browser automation needed. Runs are extremely fast and cheap (typically under $0.01 per run).

# Actor input Schema

## `mode` (type: `string`):

What to scrape: search for packages, get details for specific packages, or get download stats

## `searchQuery` (type: `string`):

Search query for finding packages (used in 'search' mode)

## `packageNames` (type: `array`):

List of package names to get details/stats for (used in 'package_details', 'download_stats', 'dependencies' modes)

## `maxResults` (type: `integer`):

Maximum number of results to return (search mode)

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

Period for download statistics

## `sortBy` (type: `string`):

Sort search results by (search mode)

## `includeReadme` (type: `boolean`):

Include package README content (slower, more data)

## Actor input object example

```json
{
  "mode": "search",
  "searchQuery": "web scraping",

```

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

// Prepare Actor input
const input = {
    "searchQuery": "web scraping",
    "packageNames": [
        "express",
        "react",
        "axios"
    ]
};

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

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {
    "searchQuery": "web scraping",
    "packageNames": [
        "express",
        "react",
        "axios",
    ],
}

# Run the Actor and wait for it to finish
run = client.actor("openclawmara/npm-package-scraper").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "searchQuery": "web scraping",
  "packageNames": [
    "express",
    "react",
    "axios"
  ]
}' |
apify call openclawmara/npm-package-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,openclawmara/npm-package-scraper"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
