CloudMade was founded by Steve Coast and Nick Black in 2007 to provide services around open mapdata. Steve Coast is also the founder of OpenStreetMap (OSM), one of the most prominent source for free map data based on the wiki idea. Therefore there is a strong relationship between OpenStreetMap and CloudMade, with the aim to “continue the democratization of geo data and to expand access to open geo data through a range of simple yet powerful tools and APIs.”
The current version of their APIs allows developers to integrate OpenStreetMap data into mobile and web-based applications. The major differences between most of similar services (beginning with Google Maps API), the CloudMade team highlights to be free from restrictive licencing.
Currently their APIs are closed pre-Alpha and is only available to registered users. To take part on this program you can sign up. They follow a bottom up approach and try to reduce complexity in terms to use geographical tools.
