Iteration depths for a 256x256 tile can be obtained through a simple HTTP API.
To request a tile simply make an http request like
http://mandelbrot.dwscript.net/api.dws?level-xxx-yyy.js
The first number is the level, the second the x coordinate in the level, the third is the y coordinate.
For instance 4-2-3.js will request a tile from level 4, at tile coordinates 2 and 3.
Valid coordinates for a a tile level go from 0 to 2^Level.
The response is a JSON array of the iteration depths on the smoothed Mandelbrot Set with the following convention:
Performance tips:
Tile databases are arranged by Level, with one SQLite 3 database per level.
Each database holds a single table named "maps" with the following fields:
The JSON iteration depth array is a single 65536 values array of integer, corresponding to the raster of the 256x256 tile (top to down).

by Eric GrangeThe databases with the raw Mandelbrot Set data are availed as bittorrent downloads.
If you find them useful, please help seed the files for a little while.
Refer to the Database documentation tab for details about how the tiles are stored.
