So I was bored and I was wondering if there were any Snapchat usernames that were a common word left to claim. Here is the code:

http = game:GetService("HttpService")
names = {"hello"}
username = ""
function req()
	local response = http:RequestAsync({
	Headers = {
	        	Accept = "*/*",
	        	["Accept-Language"] = "en-US,en;q=0.5",
	        	Referer = "https://accounts.snapchat.com/",
	        	Cookie = "xsrf_token=PlEcin8s5H600toD4Swngg; sc-cookies-accepted=true; web_client_id=b1e4a3c7-4a38-4c1a-9996-2c4f24f7f956; oauth_client_id=c2Nhbg==",
	        	["Content-Type"] = "application/x-www-form-urlencoded; charset=utf-8",
	        },
	Method = "POST",
	Url = "https://accounts.snapchat.com/accounts/get_username_suggestions?requested_username="..username.."&xsrf_token=PlEcin8s5H600toD4Swngg",
	Body = username
	})
	if response.Success then
		if http:JSONDecode(response.Body).status_code == "TAKEN" then
			return true
		elseif http:JSONDecode(response.Body).status_code == "OK" then
			return false
		else
			return false
		end
	else
		return {code=response.StatusCode,message=response.StatusMessage,body=response.Body}
	end
end
for i=1,#names do
	username = names[i]
	success,err = pcall(req)
	if typeof(err) == typeof({}) then
		print(err.code,err.message,err.body)
	else
		if err then
			print("Taken :(")
		else
			print("Avaliable :)")
		end	
	end
	wait(1)
end

I was testing if it even worked so that's why I don't have a list of words to read yet. Anyway, the code worked only for one word and it never worked again. Even if I reran the script through the command bar it still wouldn't work. The only way I was able to make it work was from closing and reopening Studio. The error that it sent was HTTP 405 Method Not Allowed, HTTP method POST is not supported by this url. This is weird because the first time I used POST it worked, but the second time it didn't. This could be a problem with my code, the website, or Roblox but I'm not sure, any help would be appreciated.
