Hi there,

Yes, the API is working. Checkout the example call:

curl --get --include "https://twitter-vugraph.p.mashape.com/vugraph?app_key=dee1eb769deb1c7ed850fc2ab18c31e5&token=3hbv1ionxeoyl9pzsy49e7bl5yh45i830nxuono4vzq309ii80whj9mu022rwgd3&twitterhandle=kimkardashian" \
  -H "X-Mashape-Key: pgLL7tiWyFmshXC6fV78WY01XA8Sp1UAUBBjsnZWb04plURaoT" \
  -H "Accept: application/json"

Thanks!
