ARCHIVE – How to register a free MapQuest API key (v3.1.1 or lower only)

Important notice: due to MapQuest basemaps now requiring their own API, making them incompatible to be implemented into a standard Leaflet installation, we had to remove MapQuest basemap support with Maps Marker Pro v4.0. Existing MapQuest maps will be switched to OpenStreetMap automatically during migration from v3.1.1 to v4.0.

Since July 11 2016, MapQuest requires to sign up for a plan on their Developer Network if you want to use their maps on your site!

A free API key allows up to 15.000 transactions/month. Higher quotas are available on demand – click here for more details.
