created_atstring date-time required
updated_atstring date-time required
last_activity_atstring date-time required
terminal_atstring date-time nullable
cost_usdnumber required
Customer cost recorded for this sandbox.
charge_state'estimated' | 'final'
Present for metered sandboxes. A terminal sandbox remains estimated while required cost records are unavailable. Show Finalizing cost until final. Historical contracts omit this field.
final_charge_usdnumber
Immutable aggregate lifetime compute charge once charge_state is final. This amount is independent of current-month readings and excludes ongoing retained-file usage. Retaining files can continue to incur separate usage charges after compute is final. Omitted while the compute cost is finalizing.
urlstring uri required
Console URL for this sandbox.
warningsstring[]
Nonfatal warnings, including bootstrap_failed when the setup command fails.
last_successful_save_atstring date-time
Last verified nonempty saved project. Absence does not imply saved application progress.
started_atstring date-time
First observed tool readiness for the current direct workspace compute session. Absent while starting and on legacy sessions without this timestamp. This is separate from creation time and changes with a replacement session.
