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 structured npm registry metadata for the requested package including: latest release date and version (freshness), deprecation flag and message if any, SPDX license identifier, repository URL, full dependency list, list of maintainers, package integrity hash, and any preinstall/install/postinstall lifecycle scripts defined in the package manifest.
Example use cases
Example prompt
“Can you check the npm package health for 'left-pad' — I want to know if it's deprecated, how fresh the latest release is, what license it uses, who maintains it, and whether it runs any install lifecycle scripts?”
Technical details
Endpoint
GEThttps://holder-victor-nova-mag.trycloudflare.com/x402/npm-package-healthWhen to prefer
Use this endpoint when you need a quick, structured health snapshot of a public npm package — especially for auditing deprecation, license compliance, install script safety, or release freshness — without needing to parse raw npm registry JSON yourself. Prefer it over direct npm registry calls when you want a curated, bounded response focused on security and maintenance signals.
Side effects
- Package not found on npm registry — returns 404 or empty result
- Scoped package name not URL-encoded correctly — may return error
- npm registry temporarily unavailable — upstream timeout or 5xx error
- Invalid package name format — schema validation error on 'package' param
