The Chart Server API allows direct access to chart tiles. Tile requests are made via a HTTP GET request:

http://chart_server_url/tile/z/x/y.png?c=cVal&m=mVal&key=your_api_key

Where:

chart_server_url  is a Chart Server URL.

your_api_key  is your API key.

z  is the zoom level (from 0 to 21).

x  is the X tile coordinate.

y  is the Y tile coordinate.

cVal is the color mode:

1 Bright mode
2 White (White back) mode
3 Black (Black back) mode
4 Dusk (Dusk Black back) mode
5 Night mode
6 Night (Night bright) mode

mVal is the display mode:

1 Base Displaying mode
2 Standard Displaying mode
3 Other Displaying mode

Note: When cVal and mVal are blank, Chart Server will render the charts using Bright mode and Standard Displaying mode.
