self.__json_content.get() can be used instead of checking membership of 'name' in the dictionary. This way looks a bit more cleaner in the code.
Also we should object mappers like there's swagger which would map contracts to proper class instances from which you can read attributes during processing.

This technique is not an actually validator deployment because you need to check field by field on JSON content, on every different route. What we really need is a middleware that handles all PUT, POST request and auto detect errors by pre-declared rules set.
