I > think the first snippet that Nikolay provided is valid from WSME standpoint. WSME is intended for building APIs with structured arguments. It seems like the case of wanting to use text/plain for a single input string argument just hasn’t come up before, so this may be a new feature. How many different API calls do you have that will look like this? Would this be the only one in the API? Would it make sense to consistently use JSON, even though you only need a single string argument in this case? > > Or if we don’t understand something in WSME philosophy then it’d nice to hear > some explanations from WSME team.

On the other hand, it sounds like perhaps your desired API may be easier to implement using some of the other tools being used, such as JSONSchema. Are you extending an existing API or building something completely new?
