How are calls defined with the map tiles?

The map's endpoint requires 3 inputs: a zoom level, an x-coordinate, and a y-coordinate. These 3 parameters are standard in the GIS/mapping world. This site provides an overview of how these 3 parameters are generated based on zoom level: https://maps.gsi.go.jp/development/tileCoordCheck.html#8/37.272/-121.772

The tiles have 3 numbers: Z/X/Y where Z = zoom, X = the x coordinate and Y = the y coordinate supplied in the API call. Each box/grid corresponds to a single call to the Maps endpoint. The above website provides the 3 parameters in that same order.
