I was reading https://jviide.iki.fi/http-redirects, which I think makes a good argument for having http calls to an API endpoint return an error rather than redirect to https. tl;dr -- for api endpoints, these are generally not meant for browsers, and it becomes easy to accidentally leak secrets as servers will call the plain text http version first.
I saw that mastodon was listed among the servers tried that redirects rather than errors, and confirmed that hachyderm.io does too.
