The hyper.sh API address is us-west-1.hyper.sh, which looks like the AWS style, however, it is not an AWS address and it is located in an independent IDC around Los Angels.
Edit: Tried it and confirmed it's indeed not on AWS, updated my previous comment.
Original: Not on AWS at all doesn't seem possible
The docs for Floating IPs [1] list 52.68.129.19 as an example, which is an AWS Elastic IP.
The docs for the API [2] says "Hyper.sh API signature algorithm is based on AWS Signature Version 4", and then proceeds to explain the differences, which is variable names. The API Domain is us-west-1.hyper.sh, which is the same URL schema as AWS (us-west-1 is also AWS's North California region).
Maybe the containers themselves are somehow not on AWS? Sure. But not on AWS at all doesn't seem to be the answer.
