jq can pull out the exact element of the json that you want, making 
further shell parsing unnecessary.
Totally unrelated example, (Adobe flash player downloads)
this query:
curl -s 
"https://get.adobe.com/flashplayer/webservices/json/?platform_type=Linux&platform_arch=x86-32&browser_dist=Chrome" 
| jq -r '.[0].download_url'
returns:
http://fpdownload.adobe.com/pub/flashplayer/pdc/32.0.0.142/flash_player_ppapi_linux.i386.tar.gz
