Character vs Characters

url/Character doesn't seem to work for me, however url/Characters does. Is there something I'm missing?

Character requires an identifier to the specific character on the path.

I.e. batmans characterurl is:

https://comicvine.gamespot.com/api/character/4005-1699/

You query url/Characters?filter=name:Batman for example to find the correct path to the character you want.
