NPM API
I'd like to know more about NPM API endpoints, Using x-spiferack: 1 which is actually used by NPM itself gives JSON response, but I think there is also another API to get users and package dependants (but I didn't find anything) could you please help?

NPM provides a public registry API, but it doesn’t officially expose endpoints for dependents or users. The x-spiferack: 1 header is an internal, undocumented API used by the npm website to fetch JSON data like dependents. It works, but it’s unreliable and may break anytime. For metadata (versions, dist-tags, downloads), you can use the official registry endpoints. For private packages, authenticated users can fetch their own package list. If you need dependents or popularity data, developers usually combine x-spiferack, the search API, or rely on third-party services like npms.io or Libraries.io, which provide more stable package insights.
