    - `day` string, date-time, required — UTC midnight of the day this usage falls in.
    - `disk_mib_seconds` number, double, required — Σ(overlap_secs × disk_mib) for this sandbox on this day — provisioned writable disk billed on the same GiB-seconds basis while the sandbox runs.
    - `mem_mib_seconds` number, double, required — Σ(overlap_secs × mem_mib) for this sandbox on this day.
    - `sandbox_id` string, uuid, required
    - `vcpu_seconds` number, double, required — Σ(overlap_secs × vcpus) for this sandbox on this day.
