NPM Package Metadata Extractor

Pull package details and statistics from the official NPM Registry for dependency audits, technology research, and supply-chain analysis. Feed it a list of package names and get back descriptions, latest versions, licenses, authors, keywords, and dependency counts — all from the public registry API without authentication.

Features

• Bulk extraction — analyze dozens of NPM packages in a single run
• Official registry — queries registry.npmjs.org directly for accurate, up-to-date data
• Rich metadata — extracts description, version, license, author, homepage, repository, keywords, and dependency count
• Repository linking — automatically cleans and normalizes Git repository URLs
• No auth required — uses the public NPM registry API
• Pay-per-result pricing — only pay for packages analyzed, with charge-limit safety

Input

Field	Type	Required	Default	Description
packages	array	Yes	—	List of NPM package names to look up (e.g. react, express, apify)
timeoutSeconds	integer	No	15	Per-request API timeout in seconds (1-120)

Input Example

{
  "packages": ["apify", "crawlee", "express"],
  "timeoutSeconds": 15
}
