The formatting of a JSON response can vary depending on the application. However, there are some general guidelines that can help with formatting. For example, Tezzard's metadata as an example can be seen here: https://tzkt.io/KT1LHHLso8zQWQWg1HUukajdxxbkGfNoHjh6/storage/12115. It is important to note that the formatting of the response can vary depending on the application. For example, My hangzhounet "copymint" metadata may have a different format than Tezzard's. Therefore, it is important to check the documentation for the specific application to make sure that the format of the response is correct.
