Developers and map mashers are now being wooed by AOL Mapquest with an offering of free APIs and a mashup contest. The API is know as the MapQuest OpenAPI and it provides a core set of mapping, geocoding and routing tools for non-commercial use. The contest begins March 7 and runs through the end of March with the winner being announced in mid April. The winning contestant will receive a $1,000 cash prize, and a trip to the Where 2.0 Conference in San Jose, Calif., from June 13-14. For more information on the contest, including Official Rules and how to enter, go to www.mapquest.com/openapi. In somewhat related news today, Yahoo! has used the O'reilly Emerging Technology Conference as a forum to announce additional offerings to their developer base. They have made available four new and enhanced Web service Application Program Interfaces (API)s through the Yahoo! Developer Network, available at http://developer.yahoo.net.
