**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

**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.
