Four new and enhanced web service Application Program Interfaces (API)s will soon be made available through the Yahoo! Developer Network. The APIs are intended to enable developers to use and build upon technology from Yahoo! Photos, Calendar, MyWeb and Shopping, creating a participatory environment that will increase the relevance of Yahoo! products and services.

Ash Patel, Chief Product Officer of Yahoo! Inc. commented, ''Developers play an important role in helping to enhance Yahoo!'s vast network of services. These new APIs along with new tools available on the Developer Network will continue to foster an environment of creativity and innovation that ultimately benefits Yahoo!'s users.''

Developer feedback has indicated that Yahoo! Shopping has enhanced its APIs with a new browse navigation feature that helps consumers quickly narrow their product search by providing the user with a menu of sub-categories and product attributes to further refine their search results. A browse shopping experience with category and attribute based refinement can also be built, allowing users to drill down and obtain product results meeting their preferred product criteria.

The Yahoo! Calendar API is intended to enable developers to write applications that make it easier for users to access their Yahoo! Calendar from other sites on the Web, enhancing the experience for millions of Yahoo! Calendar users. Yahoo! plans to make this new API available in the coming months.

The enhanced MyWeb 2.0 API provides the ability to read from as well as write to MyWeb 2.0 and is intended to enable information to move seamlessly between MyWeb and other applications or devices. Yahoo! plans to make this new MyWeb 2.0 API available in the coming months.

Additionally, the Yahoo! Developer Network is launching an Application Gallery (available at www.gallery.yahoo.com), a one-stop site for consumers to discover applications that developers have built using Yahoo! technology. The Application Gallery will provide a centralized location for established and new applications across Yahoo! properties such as Maps, Flickr, Yahoo! Music Engine and Search.

Jeffrey McManus, Director of the Yahoo! Developer Network stated, ''We are committed to providing developers with an open, easy-to-use platform to build applications and use Yahoo! technology in innovative ways. By offering more web services than any other web company, we give developers the flexibility and choice to customize our technology and contribute to new on and offline experiences for our users.''
