Na página curl man:

   -v/--verbose
          Makes the fetching more verbose/talkative. Mostly useful for debugging. A line  starting
          with '>' means "header data" sent by curl, '<' means "header data" received by curl that
          is hidden in normal cases, and a line starting with '*' means additional  info  provided
          by curl.
