After doing some researching, I would guess that googleapis.com is as safe as any google site. One site I ran across contained the following info about it:
googleapis.com is a domain used by Google APIs which is an widget company that is part of a network of sites, cookies, and other technologies used to track you, what you do and what you click on, as you go from site to site, surfing the Web. Over time, sites like googleapis.com can help make an online profile of you usually including the sites you visit, your searches, purchases, and other behavior. Your profile can then be exchanged and sold between various companies like googleapis.com as well as being sold to other advertisers and marketers.
However, this was a site selling privacy software (see
http://www.donottrackplus.com/trackers/googleapis.com.php), so from their point of view, it is not a safe site but if you try to go to
http://googleapis.com, it just brings up a the google search page (actually, the request returns a 'HTTP/1.0 302 Found' response with a redirect to the search page - my free program WebBug - downloadable from
http://www.cyberspyder.com/webbug.html - will safely show you the response details). I would expect that it is as safe as any site because any site (including other google sites) may include tracking functions - while some of us may be very concerned with privacy issues, it is hard to avoid this tracking so, personally, I just ignore the issue and don't do any surfing on my personal computer that I would not want anyone to know about. And I use Vipre anti-virus software (
http://vipreantivirus.com/) that lets me easily delete (daily) any tracking cookies I may have picked up.
