Mini-package uses grequests to pull JSON en masse.
from ggetjson import ggetjson
data = ggetjson(urls=['http://api.microprediction.org/lagged/traffic_absolute_speed.json','http://api.microprediction.org/lagged/die.json], failover_urls=None)
A bit dangerous due to the monkey patching. Use with great care if you also use requests. If you don't really need lots of requests, the getjson package is simpler. Read this issue and decide if it is worth it gevent/gevent#1016 for your purposes.
