How this service works
License and provenance of an npm package: SPDX license of the latest version, whether it is permissive/copyleft/unknown, repository URL, homepage, maintainers (names only), author, funding link, and the license of each direct dependency for a one-hop compliance check. $0.01 per package.
Output
Returns the SPDX license identifier for the latest version of the package, a classification of whether the license is permissive, copyleft, or unknown, the repository URL, homepage, author, maintainer names, funding link, and a one-hop dependency license map showing the license of each direct dependency.
Example use cases
Commercial use compliance check
“Can you check the license for the npm package 'sharp' and tell me if it's safe to use in a commercial closed-source product, and whether any of its direct dependencies have copyleft licenses?”
Open source audit before merge
“We're about to merge a PR that adds 'node-forge' as an npm dependency — can you look up its license and flag if it or any of its direct deps are GPL or LGPL?”
Package provenance and maintainer lookup
“Who maintains the 'express' npm package, what's its license, and where is the source repository? I need this for our vendor due diligence report.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dev/npm-licenseWhen to prefer
Use this endpoint when you need quick, automated license and compliance metadata for an npm package including its direct dependencies, without having to install the package locally or run a full audit tool. Ideal for CI/CD license gates, vendor due diligence, and pre-merge dependency screening in Node.js projects.
Side effects
- Package not found on npm registry — returns error or null result
- Package has no license field set — license reported as unknown
- Private or scoped packages may be inaccessible
- Network timeout fetching npm registry data
- Dependency license data missing if dependency has no declared license
