 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, DescribeAccountAttributesCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, DescribeAccountAttributesCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // DescribeAccountAttributesRequest
 *   AttributeNames: [ // AccountAttributeNameStringList
 *     "supported-platforms" || "default-vpc",
 *   ],
 *   DryRun: true || false,
 * };
 * const command = new DescribeAccountAttributesCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @param DescribeAccountAttributesCommandInput - {@link DescribeAccountAttributesCommandInput}
 * @returns {@link DescribeAccountAttributesCommandOutput}
 * @see {@link DescribeAccountAttributesCommandInput} for command's `input` shape.
