/**
 * <p>Describes the specified Spot Instance requests.</p>
 *          <p>You can use <code>DescribeSpotInstanceRequests</code> to find a running Spot Instance by
 *             examining the response. If the status of the Spot Instance is <code>fulfilled</code>, the
 *             instance ID appears in the response and contains the identifier of the instance.
 *             Alternatively, you can use <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstances">DescribeInstances</a>
 *             with a filter to look for instances where the instance lifecycle is
 *             <code>spot</code>.</p>
 *          <p>We recommend that you set <code>MaxResults</code> to a value between 5 and 1000 to
 *             limit the number of items returned. This paginates the output, which makes the list
 *             more manageable and returns the items faster. If the list of items exceeds your
 *                 <code>MaxResults</code> value, then that number of items is returned along with a
 *                 <code>NextToken</code> value that can be passed to a subsequent
 *                 <code>DescribeSpotInstanceRequests</code> request to retrieve the remaining
 *             items.</p>
 *          <p>Spot Instance requests are deleted four hours after they are canceled and their instances are
 *             terminated.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, DescribeSpotInstanceRequestsCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, DescribeSpotInstanceRequestsCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const command = new DescribeSpotInstanceRequestsCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link DescribeSpotInstanceRequestsCommandInput} for command's `input` shape.
 * @see {@link DescribeSpotInstanceRequestsCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for EC2Client's `config` shape.
