The GUIDO Engine Web API makes only use of the HTTP POST, GET, HEAD and DELETE methods.
The POST method is used to create a new score and the GET method to get the corresponding score or the score attributes.
Unless otherwise specified, the HTTP request entity-body is empty for the GET method or contains GMN code for the POST method.
The HEAD method will return the header of a server response.
Responses from the server make use of the HTTP header response code to indicate the request status, and the entity-body contains
JSON code.
