## Maps API

The CartoDB Maps API allows you to generate maps based on data hosted in your CartoDB account and style them using CartoCSS. The API generates a XYZ based URL to fetch Web Mercator projected tiles using web clients like Leaflet, Google Maps, OpenLayers.

To execute an authorized request, api_key=YOURAPIKEY should be added to the request URL. The param can be also passed as POST param. We **strongly advise** using HTTPS when you are performing requests that include your `api_key`.
