 * <p>Describes the credit option for CPU usage of the specified burstable performance
 *             instances. The credit options are <code>standard</code> and
 *             <code>unlimited</code>.</p>
 *          <p>If you do not specify an instance ID, Amazon EC2 returns burstable performance
 *             instances with the <code>unlimited</code> credit option, as well as instances that were
 *             previously configured as T2, T3, and T3a with the <code>unlimited</code> credit option.
 *             For example, if you resize a T2 instance, while it is configured as
 *                 <code>unlimited</code>, to an M4 instance, Amazon EC2 returns the M4
 *             instance.</p>
 *          <p>If you specify one or more instance IDs, Amazon EC2 returns the credit option
 *                 (<code>standard</code> or <code>unlimited</code>) of those instances. If you specify
 *             an instance ID that is not valid, such as an instance that is not a burstable
 *             performance instance, an error is returned.</p>
 *          <p>Recently terminated instances might appear in the returned results. This interval is
 *             usually less than one hour.</p>
 *          <p>If an Availability Zone is experiencing a service disruption and you specify instance
 *             IDs in the affected zone, or do not specify any instance IDs at all, the call fails. If
 *             you specify only instance IDs in an unaffected zone, the call works normally.</p>
 *          <p>For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances.html">Burstable
 *                 performance instances</a> in the <i>Amazon EC2 User Guide</i>.</p>

 * Use a bare-bones client and the command you need to make an API call.

 * // const { EC2Client, DescribeInstanceCreditSpecificationsCommand } = require("@aws-sdk/client-ec2"); // CommonJS import

 * const command = new DescribeInstanceCreditSpecificationsCommand(input);
 * const response = await client.send(command);
