## GET /api/v2/vps/{id}/storage-quota

**Get VPS storage quota**

Return storage allowance for attachable disks and the main disk. Get `{id}` from `GET /api/v2/vps`. `attachable` is the purchased Attachable Block Storage pool used by `POST /api/v2/vps/{id}/actions/add-disk` and non-root disk growth; `attachable.availableGb` is the remaining capacity an agent can spend before buying more. If a requested new disk or resize exceeds `attachable.availableGb`, do not retry the disk action with a larger body; first use `GET /api/v2/vps/{id}/actions/upgrade` and `POST /api/v2/vps/{id}/actions/config` with `resources.additionalStorageGb`, then re-read this endpoint. `mainDisk.purchasedGb` is the root/main disk allocation; increase it with the `storageGb` configurable option, not with `additionalStorageGb`. Use `attachable.upgradeAvailable` before offering extra disk/storage purchase flows; disk-resize writes use the VPS action endpoints, not this read endpoint.
