 All endpoints return JSON data. POST request can be made with query string or form data arguments, but this is discouraged - JSON should be used whenever possible.
 
 No application should ever rely on the non-existence of fields in the JSON data - i.e., additional fields can be added at any time without this being considered a breaking change. Existing fields should usually not be removed or changed, but it is always a good idea to add basic handling for missing fields.
