How this service works
npm package info: latest version, license, dependencies count and weekly downloads. Input: a package name.
Output
A JSON object containing the package name, current latest version, SPDX license string, homepage URL, repository URL, short description, total number of dependencies, and weekly download count from npm.
Example use cases
Vetting a new dependency
“Before I add react-query to my project, can you pull up its npm info — latest version, license, number of dependencies, and weekly downloads so I can see how actively it's used?”
Checking OSS license compliance
“I need to make sure chalk uses an MIT or Apache license before we use it in our product — can you look it up on npm?”
Comparing package popularity
“How many weekly downloads does moment get on npm right now? I want to compare it against day.js to decide which to use.”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/npm-package?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, structured summary of an npm package's current state — version, license, popularity, and dependency footprint — without having to scrape the npm website or call the full npm registry API directly. Ideal for agents doing dependency vetting, license compliance checks, or package popularity comparisons.
Side effects
- Package name not found on npm registry — may return an error or empty result
- Misspelled or scoped package names (e.g. missing @scope/ prefix) may fail to resolve
- Data may be slightly stale if the npm registry cache has not refreshed
- Very new packages with no download history may return zero weekly downloads
