The following code examples show how to use `DescribeSpotInstanceRequests`.

------
#### [ CLI ]

**AWS CLI**  
**Example 1: To describe a Spot Instance request**  
The following `describe-spot-instance-requests` example describes the specified Spot Instance request.  

```
aws ec2 describe-spot-instance-requests \
    --spot-instance-request-ids sir-08b93456
```
Output:  

```
{
    "SpotInstanceRequests": [
        {

                    {
                        "DeleteOnTermination": true,

                    "AvailabilityZone": "us-east-2b",
                    "Tenancy": "default"
                },
                "Monitoring": {
                    "Enabled": false
                }
            },
            "LaunchedAvailabilityZone": "us-east-2b",
            "ProductDescription": "Linux/UNIX",
            "SpotInstanceRequestId": "sir-08b93456",
            "SpotPrice": "0.010000"
            "State": "active",
            "Status": {
                "Code": "fulfilled",
                "Message": "Your Spot request is fulfilled.",
                "UpdateTime": "2018-04-30T18:16:21.000Z"
            },
            "Tags": [],
            "Type": "one-time",
            "InstanceInterruptionBehavior": "terminate"
        }
    ]
}
```
**Example 2: To describe Spot Instance requests based on filters**  
The following `describe-spot-instance-requests` example uses filters to scope the results to Spot Instance requests with the specified instance type in the specified Availability Zone. The example uses the `--query` parameter to display only the instance IDs.  

```
aws ec2 describe-spot-instance-requests \
    --filters Name=launch.instance-type,Values=m3.medium Name=launched-availability-zone,Values=us-east-2a \
    --query "SpotInstanceRequests[*].[InstanceId]" \
    --output text
```
Output:  

```
i-057750d42936e468a
i-001efd250faaa6ffa
i-027552a73f021f3bd
...
```
For additional examples using filters, see [Listing and filtering your resources](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Filtering.html#Filtering_Resources_CLI) in the *Amazon Elastic Compute Cloud User Guide*.  
**Example 3: To describe Spot Instance requests based on tags**  
The following `describe-spot-instance-requests` example uses tag filters to scope the results to Spot Instance requests that have the tag `cost-center=cc123`.  

```
aws ec2 describe-spot-instance-requests \
    --filters Name=tag:cost-center,Values=cc123
```
For an example of the output for `describe-spot-instance-requests`, see Example 1.  
For additional examples using tag filters, see [Working with tags](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html#Using_Tags_CLI) in the *Amazon EC2 User Guide*.
