How to get all direct package dependants

[MarcoPellero]

Hi, i'm not sure if this is the repo i should open this issue in, i couldn't find the repo for the npmjs.com site.
I'm sorry if it isn't.

I'm trying to build a tool that finds all packages that indirectly depend on a specified package, and for this, i need to be able to find all packages that directly depend on a specified package.
This can be found on npmjs.com, for any given package you can see how many packages directly depend on it, and you can browse those dependants in "pages" (36 at a time).
Example: the direct dependents of the https package

I wrote some code to read these pages from the API, but it crashed before reading all of them, and upon further inspection i noticed that both on the API and on the site itself, you can only browse the first 11 pages, so, you can see at most 396 dependents of a package, after that, the "next page" button disappears.
By the way, when i say API, i'm replicating the site's requests. If you add the x-spiferack: 1 header, you get back json instead of html.

I was wondering why this limit is in place, if it could be removed, and/or if there's any other way to read this data, maybe straight from the registry.
I tried looking at the registry but i couldn't figure out whether it was possible to get this data from there.

For now, i hardcoded a limit to my tool so that i could still work on the rest of it while waiting to find a solution to this, but now i think i'm getting rate-limited: after a bit, requests return error code 1015, and it keeps returning only that for a while, though the site works, which is weird since i'm basically doing the same requests

I don't believe this is possible w/ the current registry endpoints. This is a question for registry support, not an npm cli bug.
