## 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

## Package Registry Intelligence — npm, PyPI, crates & more 📦

**One tool over six software package registries — npm, PyPI, crates.io, RubyGems, NuGet and Packagist. Look up a list of packages or search an ecosystem, and get every package in ONE unified schema: version, license, repository, maintainer, downloads and dependency count. No API key.**

Most software depends on packages from a handful of registries. This Actor speaks all the big public ones and normalizes them into a single schema — so you can enrich a dependency list, audit a supply chain, or research a whole ecosystem regardless of language.

**npm · PyPI · crates.io · RubyGems · NuGet · Packagist**

***

### What you get per package

`ecosystem` · `name` · `version` · `description` · `license` · `homepage` · `repository` · `author` · `keywords` · `downloads` · `downloads_period` · `dependencies_count` · `published_at` · `package_url`.

### Input

**Look up packages** — give each as `ecosystem:name`:

| Ecosystem | Example |
|---|---|
| `npm` | `npm:express` |
| `pypi` | `pypi:requests` |
| `crates` | `crates:serde` |
| `rubygems` | `rubygems:rails` |
| `nuget` | `nuget:Newtonsoft.Json` |
| `packagist` | `packagist:monolog/monolog` |

```json
{ "mode": "packages", "packages": ["npm:express", "pypi:requests", "crates:serde"] }
```

**Search an ecosystem** by keyword (all except PyPI):

```json
{ "mode": "search", "searchEcosystem": "npm", "searchQuery": "http client", "maxResults": 50 }
```

### Use cases

- **Software supply-chain & SBOM** — enrich a dependency manifest with license, repo, maintainer and popularity across languages.
- **Security & risk** — spot unmaintained, unlicensed or low-adoption dependencies.
- **Dev-tool market research** — search and rank packages in any ecosystem by downloads.

### Notes

- **No API key.** Uses each registry's public API.
- **Downloads** semantics differ by registry: npm reports **last-month** installs; crates/RubyGems/NuGet/Packagist report **total** downloads; PyPI's main API exposes no download count (`downloads` is null). The `downloads_period` field tells you which.
- **PyPI has no search API**, so search mode supports the other five ecosystems.
- Package metadata belongs to its authors and is subject to each package's license.

#### Keywords

# Actor input Schema

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

packages = look up a list of packages; search = search one ecosystem by keyword.

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

One entry per package as `ecosystem:name`. ecosystem ∈ npm, pypi, crates, rubygems, nuget, packagist. Examples: "npm:express", "pypi:requests", "crates:serde", "rubygems:rails", "nuget:Newtonsoft.Json", "packagist:monolog/monolog".

## `searchEcosystem` (type: `string`):

Which registry to search. PyPI is not searchable via API.

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

Keyword to search, e.g. "http client", "logging", "orm".

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

Cap on packages returned in search mode.

## Actor input object example

```json
{
  "mode": "packages",
  "packages": [
    "npm:express",
    "pypi:requests",
    "crates:serde",
    "rubygems:rails",
    "nuget:Newtonsoft.Json",
    "packagist:monolog/monolog"
  ],
  "searchEcosystem": "npm",
  "maxResults": 50
}
```

# 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 = {
    "packages": [
        "npm:express",
        "pypi:requests",
        "crates:serde",
        "rubygems:rails",
        "nuget:Newtonsoft.Json",
        "packagist:monolog/monolog"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("straightforward_hydra/package-registry-intelligence").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);
});

print("💾 Check your data here: https://console.apify.com/storage/datasets/" + run["defaultDatasetId"])
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
