So, you want to find level 10s (or any other level of wilds) near predefined coordinates.
When the game is loaded, a file called 'map.bin' is prefetched. This file contains one whole realm of coordinates regarding wilds, cities and their level. (not ownership - although you can fetch that too, using the tile_at.json API call, if you know how to use it.)
The file can be easily found in your browser's cache. OR just point to a realm's full address (http://realm291.c13.castle.wonderhill.com/map.bin) < It's not protected, you can get the map.bin for all realms without authentication.
This small yet useful .php file reads the map.bin, and outputs (can be put in Sql for all your needs) all of the realm coordinates in format XY, and the wild type/level.
Kabam did not encrypt this file with any algorithm, and its decoding is fairly easy.
Usage: just place map.bin in the same directory as map.php and run it.
Example output for Realm Mesite: (the binary corresponds to the decoding - if you don't know what it is, then ignore it.)
Bugs: 'level' of cities is incorrect. Blame Kabam. :P

(etc etc, until 749x749)
Note: the map.bin file contains the whole 750x750 (0-749x0-749) coordinates (562500 tiles total), and the first 2 bytes are bogus. Yes, 2 full bytes! That's the whole range of Kabam's attempt at protecting this file's data. So, the map.bin file has 562502 bytes. Duh.
Shoutouts: Semper Fi. No one else at the moment. :P
