Subsequently, tiles are retrieved with HTTPS GET requests, providing the zoom level (z), x and y coordinates, and the session token. An example demonstrates requesting a tile at zoom level 10, with coordinates (192, 401). The tile data downloads to a local file, without a server response message.\n"]]
