NPM Package Tracker — Metadata + Download Stats

Snapshot NPM package metadata and weekly/monthly download statistics via the public registry.npmjs.org and api.npmjs.org/downloads endpoints. One row per package — version, dependencies count, repository, maintainers, and download totals. No authentication required.

Example output row

{
  "snapshotAt": "2026-06-03T11:00:00+00:00",
  "name": "react",
  "description": "React is a JavaScript library for building user interfaces.",
  "latestVersion": "18.3.1",
  "createdAt": "2011-10-26T17:46:21.943Z",
  "modifiedAt": "2024-04-26T12:00:00.000Z",
  "license": "MIT",
  "homepage": "https://reactjs.org/",
  "repositoryUrl": "git+https://github.com/facebook/react.git",
  "maintainers": ["fb", "reactjs"],
  "keywords": ["react"],
  "dependenciesCount": 3,
  "peerDependenciesCount": 0,
  "devDependenciesCount": 0,
  "downloadsLastMonth": 2800000000,
  "downloadsLastWeek": 680000000
}

How to use

Input schema:

Field	Type	Default	Description
packages	string[]	["react","next","vue","svelte"]	NPM package names to fetch
includeDownloads	boolean	true	Also fetch download counts from api.npmjs.org

Example input:

{
  "packages": ["react", "next", "typescript", "tailwindcss"],
  "includeDownloads": true
}

When includeDownloads is true, the actor makes two requests per package (registry + downloads). Set it to false to halve request count and speed up the run when download stats are not needed.

Pricing

Event: package_snapshot — $0.0002 per package row

One charge per package successfully fetched. Packages that return 404 or error are not charged.

Buyer

• Track competitor NPM package growth week-over-week by storing snapshots daily.
• Monitor dependency counts across your supply chain for security triage.
• Build dashboards comparing download velocity across framework ecosystems.
• Qualify open-source libraries before adoption — license, maintainers, activity.
• Feed package metadata into LLM pipelines for automated dependency analysis.

Source

• Registry metadata: https://registry.npmjs.org/{package} — public, no auth, full package document
• Download stats: https://api.npmjs.org/downloads/range/last-month/{package} — returns 30 daily counts; actor sums them for monthly total and last-7-days weekly total
