That sounds like an excellent approach. If a consumer chooses "always 200 on error", how do you return the API response status? HTTP Response Header or in a custom value in the response body?

Thanks. Error responses from our API always generate a JSON object with top level error and error_description attributes, while non-errors never contain a top level error attribute. It might be interesting to add a response header to disambiguate even more.
