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

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 & Downloads Lookup (Free) Bulk-lookup **npm packages** and get clean, structured JSON: latest version, **weekly and monthly downloads**, dependencies, license, repository link, maintainers count, first/last publish dates and deprecation status. Uses the official npm registry and downloads APIs — no API key needed. This actor is **100% free**: you only pay your own Apify platform usage. ### Input | Field | Type | Description | |---|---|---| | `packages` | array | npm package names (scoped `@scope/name` supported). | | `includeDownloads` | boolean | Fetch weekly/monthly download counts. Default `true`. | ### Output One dataset item per package: ```json { "status": "found", "package": "express", "latestVersion": "5.2.1", "description": "Fast, unopinionated, minimalist web framework", "license": "MIT", "repository": "https://github.com/expressjs/express", "npmUrl": "https://www.npmjs.com/package/express", "maintainersCount": 3, "dependenciesCount": 27, "versionsCount": 280, "createdAt": "2010-12-29T19:38:25.450Z", "lastPublishedAt": "2026-05-01T12:00:00.000Z", "deprecated": null, "weeklyDownloads": 109156326, "monthlyDownloads": 468000000 } ```` Unknown packages yield `status: "not_found"`; network failures yield `status: "error"` with an `error` message — the run never crashes. ### Use cases - Dependency audits: check license, deprecation and freshness of your stack. - Developer-tools market research: compare adoption of competing libraries. - Tech due diligence: evaluate the health of open-source dependencies. - Feed dashboards or AI agents with live npm ecosystem data. ### Limitations & fair use - Download counts come from the public npm API and update daily. - Polite delays are applied between requests to respect the registry. *** **This actor is free** — you only pay standard Apify platform usage. More actors by this developer: [fit\_melon on Apify Store](https://apify.com/fit_melon). # Actor input Schema ## `packages` (type: `array`): npm package names to look up (scoped packages like @scope/name are supported). ## `includeDownloads` (type: `boolean`): Fetch weekly and monthly download counts from the npm downloads API. ## Actor input object example ```json { "packages": [ "express", "react" ], "includeDownloads": true } ``` # 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 '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "packages": [ "express", "react" ] }; // Run the Actor and wait for it to finish const run = await client.actor("fit_melon/npm-package-stats-lookup").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); }); // 📚 Want to learn more 📖?
