The EC2 -> Instances -> Reserved Instances shows some 3d party instances available for purchase:

How can this list be obtained with the AWS CLI?

I’ve tried:

aws ec2 describe-reserved-instances-offerings --availability-zone us-east-1e --include-marketplace --filters Name=marketplace,Values=true > output.txt

But it sometimes returns 125MB worth of data (with hundreds of m5a.large instances while the UI only shows a handful), other times it only returns 5KB with 5 instances total.

What’s the proper command to use to obtain a correct list of 3d party instances?
