npm Package Intelligence — Registry, Downloads & Health Scores

SEO title: npm Package Scraper | Downloads, Dependencies, Maintainers & Health Score
SEO description: Search npm or look up exact packages. Get official download counts, dependencies, publish recency, maintainers, and a maintenance health score. Scoped packages supported. No API key.

Turn the public npm registry + download APIs into a clean Apify dataset for supply-chain reviews, competitor package tracking, SEO/dev-tool research, and agent workflows.

Why this beats typical Store competitors

Existing npm Actors on the Store mostly have ~3 users and stop at shallow metadata. This Actor:

• Combines search + exact package lookup (including scoped packages like @types/node)
• Pulls official api.npmjs.org download points: last-day / week / month / year
• Enriches with packument data: version count, dist-tags, dependency counts, publish timestamps, deprecation
• Computes a transparent healthScore (popularity + publish freshness + maintainers + repo presence − huge dep trees)
• Optional per-version last-week downloads
• Exposes npm search quality / popularity / maintenance weights

Example input

{
  "mode": "both",
  "query": "http client",
  "packageNames": ["express", "lodash", "@types/node"],
  "maxResults": 10,
  "includePackument": true,
  "includeDownloads": true
}

Example output (truncated)

{
  "name": "express",
  "version": "5.3.0",
  "license": "MIT",
  "downloadsLastDay": 25000000,
  "downloadsLastWeek": 194000000,
  "downloadsLastMonth": 571000000,
  "dependenciesCount": 30,
  "maintainersCount": 5,
  "daysSincePublish": 25,
  "healthScore": 91.4,
  "repositoryUrl": "https://github.com/expressjs/express",
  "npmUrl": "https://www.npmjs.com/package/express",
  "source": "npmjs.com"
}

Suggested pay-per-event pricing

Event	Suggested price
Actor start	$0.0005
Per enriched package	$0.003 – $0.008

Enrichment hits several endpoints per package, so price above plain search scrapers. Start around $0.005 / package.
