aws support describe-services

Returns the current list of AWS services and a list of service categories for each service. You then use service names and categories in your CreateCase requests. Each AWS service has its own set of categories. The service codes and category codes correspond to the values that appear in the Service and Category lists on the AWS Support Center Create Case page. The values in those fields don't necessarily match the service codes and categories returned by the DescribeServices operation. Always use the service codes and categories that the DescribeServices operation returns, so that you have the most recent set of service and category codes. You must have a Business or Enterprise support plan to use the AWS Support API. If you call the AWS Support API from an account that does not have a Business or Enterprise support plan, the SubscriptionRequiredException error message appears. For information about changing your support plan, see AWS Support


--service-code-list <list>A JSON-formatted list of service codes available for AWS services
--language <string>The ISO 639-1 code for the language in which AWS provides support. AWS Support currently supports English ("en") and Japanese ("ja"). Language parameters must be passed explicitly for operations that take them
--cli-input-json <string>Performs service operation based on the JSON string provided. The JSON string follows the format provided by ``--generate-cli-skeleton``. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally
--generate-cli-skeleton <string>Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value ``input``, prints a sample input JSON that can be used as an argument for ``--cli-input-json``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command
