Get the workspace usage, Computer, and spend series

Aggregates the UsageLedger into aligned UTC calendar-day buckets over an inclusive from and exclusive to range of at most 90 days. Usage buckets carry exact token totals, sandbox active_ms, and snapshot storage_mib_ms; sibling Computer buckets carry each provider-metered dimension as an exact decimal string with fact, late, final, and provisional counts; sibling spend buckets carry signed exact pico-USD as a decimal string with their own completeness status, and a missing platform charge is a named state rather than zero. Select monetary_view event_time to place corrections in the original work’s bucket or accounting_time to place them when recorded. A bucket whose end is later than the response’s as_of is explicitly marked incomplete.

Checkfu support posture: alpha; hosted. Required evidence journey: usage-series. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
