 # Maps API

-The CartoDB Maps API allows you to generate maps based on data hosted in your CartoDB account and apply custom SQL and CartoCSS to the data. The API generates a XYZ-based URL to fetch Web Mercator projected tiles, using web clients such as [Leaflet](http://leafletjs.com), [Google Maps](https://developers.google.com/maps/), or [OpenLayers](http://openlayers.org/).
+The CARTO Maps API allows you to generate maps based on data hosted in your CARTO account and apply custom SQL and CartoCSS to the data. The API generates a XYZ-based URL to fetch Web Mercator projected tiles, using web clients such as [Leaflet](http://leafletjs.com), [Google Maps](https://developers.google.com/maps/), or [OpenLayers](http://openlayers.org/).

 You can create two types of maps with the Maps API:

 - **Anonymous Maps**  
-  You can create maps using your CartoDB public data. Any client can change the read-only SQL and CartoCSS parameters that generate the map tiles. These maps can be created from a JavaScript application alone and no authenticated calls are needed. See [this CartoDB.js example](/cartodb-platform/cartodb-js/getting-started/).

 - **Named Maps**  
  There are also maps that have access to your private data. These maps require an owner to setup and modify any SQL and CartoCSS parameters and are not modifiable without new setup calls.

 Some notes about filtering:

  - Invalid index values or out of bounds indexes will end in `Invalid layer filtering` errors.
-  - Once a Mapnik layer is selected, all Mapnik layers will get blended. As this may change in the future **it is
-  recommended** to always select all Mapnik layers if you want to select at least one so you will get a consistent
-  behavior in the future.
  - Ordering is not considered. So right now filtering layers 0,3,4 is the very same thing as filtering 3,4,0. As this
