Api Endpoint

NPM Package Lookup

One merged call instead of two: latest-version metadata from the official npm registry plus last-week download count from api.npmjs.org (both live). Query: ?pkg=react (scoped names like @scope/name accepted). Returns version, license, deps_count + dependency names, engines, weekly_downloads. No personal maintainer data. 1h cache.
