Unfortunately, there is not an API to get AMI ID directly from an EBS snapshot.

Instead, you can go the other way.

1. Use ec2:DescribeImages to get a list of AMI images.
2. For each AMI image returned, examine the list of EBS snapshots associated with the AMI image.
3. See if the EBS snapshot in question is included.

Edit: Another possibility:

You may be able to use ec2:DescribeImages with a filter on the EBS snapshot ID.

https://ec2.amazonaws.com/?Action=DescribeImages
 &Filter.1.Name=block-device-mapping.snapshot-id
 &Filter.1.Value=snap-xxxx
