Great for giving each agent their own S3 bucket without having to worry about cleaning it up to reclaim quotas.

The closest thing that exists to this is the Tigris partner API, but other than that I could not find anything that allows unlimited S3 buckets like this. AWS has a 10k buckets (can go up to 1M) and 5k users limit, which is obviously way too low (and a ceiling to track/worry about) when you're creating and destroying buckets quickly.
