At the beginning of this year, the Yahoo! Front Page team embarked on an ambitious project to completely remake the face of the company. The goal was to make the Front Page into the most important starting point on the web while also showcasing Yahoo!’s commitment to openness. From the engineering team’s perspective, this meant turning the Front Page into a framework upon which Yahoo! and its partners could build new functionality and experiences rapidly.
Yahoo! Open Strategy (Y!OS) platform launch gives you something to get your hands on to various Yahoo! Services. Today Yahoo! is making Y!OS a reality for developers through the release of the Yahoo! Application Platform (YAP), Yahoo! Social Platform (YSP) and Yahoo! Query Language (YQL). Now, anyone on the web has access to Yahoo!’s tools and data to start building applications for Yahoo!’s vast audience and the web beyond.
Everybody is opening up their closets these days — freeing up their source codes, bare opening their APIs. Yahoo! have released their Address Book API, which will give 3rd party developers access to Yahoo! users’ contact lists without the need for those traditional and primitive method of page scraping.
The Yahoo! Address Book (AB) API is a JSON/XML interface for accessing and updating the Yahoo! Address Book using a web service. It can be used to look up addresses for auto-completion of emails, to add addresses for future shipping information, to obtain unique identifiers for network invites, or to sync with another address book.
With this new release, there is no policy in place for restricting how long developers can store and use the data they pull from the API. But, as with many of its developer initiatives, Yahoo reserves the right to stop what it deems bad behavior. The Yahoo! Address Book API is limited to 5,000 queries per IP per day.

Google have also released their Contact API few months ago.
