How to make another process in mod

So i'm making a mod that access's an api that takes like 10 seconds to load. Currently my game stops working for those 10 seconds. I was woundering if there is a way to run the API part in a different process and what method I would use.

@SubscribeEvent
    public void onPlayerTick(EntityItemPickupEvent event) throws IOException {
        //API function that takes a while to finish
        String response = Scan();
        //Rest of stuff
        ChatStyle link = new ChatStyle();
        link.setChatClickEvent(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "/seed"));
        IChatComponent text = new ChatComponentText("WORKING").setChatStyle(link);
        System.out.println(response);
        Minecraft.getMinecraft().thePlayer.addChatMessage(text);

Thanks
