-**TILES**
-
-[GET] subdomain.cartodb.com/tiles/:table_name/:z/:x/:y.[png|png8|grid.json]
-
-Args:
-
-* sql - plain SQL arguments
-* interactivity - specify the column to use in UTFGrid
-* cache_buster - Specify an identifier for the internal tile cache.
-                 Requesting tiles with the same cache_buster value may
-                 result in being served a cached version of the tile
-                 (even when requesting a tile for the first time, as tiles
-                 can be prepared in advance)
-* cache_policy - Set to "persist" to have the server send an Cache-Control
-                 header requesting caching devices to keep the response
-                 cached as much as possible. This is best used with a
-                 timestamp value in cache_buster for manual control of
-                 updates.
-* geom_type - override the cartodb default
-* style - override the default map style with Carto
