How pools use the space

[ferp]

Hi, i'm workin with the api in the proxmox to get the available space we had in differents pools, but i see some curious thing with the api I get 9.6 tb availble but in the web interface show me with a simple substraction the space availble is 10 tb approximately, with gemini explain that is because the pool use part of the space can not assign to new vm's, someone have the web or documentation official where i can check ?

note: srry for my english i'm learning

Which endpoints are you using to get the pool size?
One thing to double-check: get /nodes/<node>/storage/<id>/status returns values in GiB/TiB, while the web displays them as GB/TB.
