How this service works
Inspect current public npm registry metadata for release freshness, deprecation, license, repository, dependencies, maintainers, integrity, and install lifecycle scripts.
Output
Returns a structured snapshot of the npm package's current public registry metadata, including: version history and latest release date (freshness), deprecation flag and message, declared license, linked repository, list of dependencies, maintainer identities, package integrity hashes, and any install/uninstall/preinstall/postinstall lifecycle scripts declared in the package manifest.
Example use cases
Auditing OSS dependency before adoption
“Before we add 'axios' as a dependency, can you check its npm health — is it deprecated, when was it last released, who maintains it, and does it have any postinstall scripts I should know about?”
Verifying license compliance for a package
“I need to know the license for the npm package '@babel/core' — can you fetch its current npm registry metadata so I can confirm it's MIT-compatible?”
Checking if a package is still actively maintained
“Can you look up the npm package 'request' and tell me when it was last released and whether it's been marked as deprecated? I want to know if we should migrate away from it.”
Technical details
Endpoint
GEThttps://supported-rely-thee-portion.trycloudflare.com/x402/npm-package-healthWhen to prefer
Choose this endpoint when you need a bounded, reproducible snapshot of public npm package health metadata without running npm install yourself. Ideal for supply chain auditing, license compliance checks, deprecation detection, and lifecycle script inspection before adopting or updating a dependency. Prefer this over direct npm CLI calls when operating in an agent or serverless context without a local Node environment.
Side effects
- Package not found on the public npm registry — returns an error indicating the package name is invalid or unscoped/scoped name is malformed
- Network or upstream npm registry unavailability — may return a timeout or upstream error
- Rate limiting from the npm registry — snapshot may fail or return partial data
- Private or unpublished packages — not accessible via public registry endpoints
