I am trying to build a plugin that connects to an API to fetch a list of products and display information about each of them. I understand that I will most likely use the HTTP API provided from WordPress, but I found the documentation very vague and I don't know where to start. I searched for other materials on this matter but I couldn't find anything related to WP plugins that get data from external APIs.

Does anyone know any good resource about this or have any suggestion about what steps I should follow?

EDIT: What I am looking for is maybe an example of how the WP HTTP API is used in a WP Plugin. I have searched everywhere but all I can find is the WP REST API and that is something completely different from what I am looking for.

This post on Sitepoint is a bit old, but still does a pretty good job at explaining the different parts of the HTTP API: https://www.sitepoint.com/the-wordpress-http-api/

Just be sure to look up the functions mentioned there to see if they changed in the past four years.

Thank you, that seems useful. It doesn't have any explanation how the HTTP API would be used inside a plugin though.
