Checking if a player is following another player?

What am i trying to do

Make a custom player list / leaderboard to replace the new player list with an old version, i have finished friends, owner, mods. What am i trying to do is detect if someone is following or being followed by someone.

Problem

There is no function to get it thats built-in roblox lua, i have tried with api.roblox.com (using a proxy) and i get 403 Forbidden

My attempts to resolve the problem

I have tried to use HTTP Service and connect to api.roblox.com through rprxy.xyz, but i just get 403 Forbidden and HTTPService is enabled.

local http = game:GetService("HttpService")
local request = http:RequestAsync({
Url = "api.rprxy.xyz",
Method = "GET",
Headers = {
userId = tostring(game.CreatorId),
followerUserId = tostring(1)
}
})
function iter(table,func)
for i,v in pairs(table) do
func(i,v)
end
end
iter(request,function(Key,Value) 
print(Key.."\n "..tostring(Value))
end)
--[[
Returns  Code 403 Error Forbidden
]]--

Question

What could i do to fix this problem?
