How this service works
Latest version, publish date, licence, weekly downloads, dependencies, engines and deprecation status of an npm package.
Output
A JSON object containing the npm package's latest version number, publish date of that version, licence type, weekly download count, list of dependencies, supported engines (Node.js version range etc.), and whether the package has been marked as deprecated.
Example use cases
Checking if a dependency is outdated
“Can you look up the current version of lodash on npm and tell me when it was last published? I want to know if the version in my package.json is still up to date.”
Auditing package licence before use
“What licence does the axios npm package use? I need to check before we add it to our project.”
Verifying deprecation before production use
“Is the request npm package still actively maintained or has it been deprecated? Also, how many weekly downloads is it getting right now?”
Technical details
Endpoint
GEThttps://api.cra-agent.tech/v1/paid/packages/npm?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date npm package metadata (version, licence, downloads, deprecation) without scraping npmjs.com or setting up your own registry client. Prefer it for automated dependency auditing, licence compliance checks, or keeping agents informed about the health and currency of JavaScript/Node.js dependencies.
Side effects
- Package name not found — returns a 404 or empty result if the package does not exist on npm
- Scoped package names must be correctly URL-encoded (e.g. @types/node)
- Rate limiting or payment failure may return a 402 or 429 error
- npm registry unavailable — upstream timeout may cause delayed or failed response
- Private or unlisted packages will not be accessible
