When calling GET /character/:id, the jobs are represented as as object containing objects, but there's no way (no property) to know if the job is a Disciple of Hand, War or Hand.
It could be implemented as a simple field which exposes an enum of ["DoH", "DoW", "DoL"].
Also, jobs should be an array to be easily parseable.
I didn't find any CONTRIBUTING.md file, so I don't know if you accept Pull requests or not (and where is the API code too)
