Request body fields

Name	Type	Required	Description

Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key `Owner` and the value `TeamA`, specify `tag:Owner` for the filter name and `TeamA` for the filter value. `tag-key` - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value. `vpc-id` - The ID of the VPC to which the instance is linked. `vpc-id` - The ID of the VPC that the instance is linked to.
