Get contact list from gmail, yahoo, hotmail

问题

I wish to write an API that can get the contacts list from Gmail, Yahoo and other e-mails. How can this be done? Are there already existing APIs for them or do I need to write PHP code to extract information?

I need a referral system like DropBox has. Has anyone coded it themselves or is it available as open source?

https://www.dropbox.com/referrals

Please guide me in this regard. Any link or explanation will do the job.

Thanks :)

Google has an API: http://code.google.com/intl/en/apis/contacts/ And Yahoo also has an API: http://developer.yahoo.com/social/contacts/

There exists some other which are mentioned in this thread: PHP APIs for Hotmail, Gmail and Yahoo?
