Requests will return an appropriate status code.
It is possible to suppress the error codes by passing allowError=false in the query. In that case, the status will always be 200, barring a 500 error from the server itself.
An error response will describe the specifics of any errors.
|Error Code||Error Name||Description|
|200||OK||Request was fulfilled|
|400||Bad Request||Request had bad syntax or the parameters supplied were invalid|
|403||Forbidden||Valid API Key was not supplied in the query|
|404||Not Found||Server has not found a route matching the given URI|
|500||Internal Error||Server encountered an unexpected condition which prevented it from fulfilling the request|
