When I saw that User Local had released a service called “G+Navi Google+ Ranking,” I wondered if Google+‘s API had already been released, so I looked into it.

・G+Navi Google+ Ranking (Japan Domestic Circle Count)

Currently, it seems there are unofficial APIs available.

・PHP API：jmstriegel/php.googleplusapi - GitHub

【Reference】

・Tried Using PHP Library to Get Information with Google+ Unofficial API - Shin x blog

・Is there already a Google+ API? - Stack Overflow

・Developer API for Google+: It’s coming | Rafe’s Radar - CNET News

I wonder when the official API will come out?

That’s all from the Gemba.
