I use in my project OpenstreetMap and Leaflet. Add a layer:
L.tileLayer("http://{s}.tile.cloudmade.com/{my_key}/997/256/{z}/{x}/{y}.png",
attribution: "Map data © <a href=\"http://openstreetmap.org\">OpenStreetMap</a> contributors, <a href=\"http://creativecommons.org/licenses/by-sa/2.0/\">CC-BY-SA</a>, Imagery © <a href=\"http://cloudmade.com\">CloudMade</a>"
).addTo map
But today I received a letter from CloudMade.....
As of May 1st we’ll be stopping service to your API key. This means that CloudMade services like Map Tiles, Geocoding and Routing that you maybe using in your apps or websites will stop working.
And how to add the map without this API?
