Yahoo! Opens Search Marketing API

Yahoo! said today that it has opened up an API to its new "Panama" search marketing application interface. Yahoo said that the new application programming interface (API) will allow ad agencies, technology partners, and others to integrate and build on the firm's search marketing offering. Access to the programming interface is free. API access will be given to partners in three different levels, including basic free access; an advanced access program which also includes account management and service level commitments; and an elite level to providers such as Efficient Frontier, Omniture, SearchIgnite and The Search Agency.
