I want to implant ChatGPT into my roblox game, but how?

(Client / Local Script)

Error: “Unrecognized request option url”

game.Players.PlayerAdded:Connect(function(player) --Whenever a player joins
	player.Chatted:Connect(function(message) --When a player messages
		local HttpService = game:GetService("HttpService")
		local Success, Err = pcall(function()
			Request = HttpService:RequestAsync(
				{
					url = "https://api.openai.com/v1/completions/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",
					method = "GET",
					Headers = {
						["type"] = "application/json",
						["message"] = message,
						["id"] = "",
						["name"] = "Chatbot"
					},
				}
			)
		end)
		if not(Success)then --if error
			warn(Err)
		else --if sucess
			print(Request.Body)
		end
	end)
end)
