Error Codes

[Bobspadger]

Instead of using requests.raise_for_status() maybe inspect the error code, and return the friendly error along with an exception to enable better and easier access

This shows itself as not being the best way to handle errors as it wipes the json and the helpful errors out from the 400 response.

these can contain helpful information such as 'Email required'
