Fields
  • active — Whether the account is currently active for subscription usage.
  • limits.daily, limits.monthly — Configured daily/monthly allowance.
  • enforceDailyLimit — If true, access requires both daily AND monthly remaining > 0; if false, only monthly remaining is required.
  • daily.used, monthly.used — Usage units consumed in the current day/month window.
  • daily.remaining, monthly.remaining — Remaining allowance for each window.
  • daily.percentUsed, monthly.percentUsed — Decimal fraction in [0,1].
  • daily.resetAt, monthly.resetAt — Millisecond epoch when the window resets.
  • period.currentPeriodEnd — ISO timestamp for the end of the current billing period, if known.
  • state — One of active, grace, inactive.
  • graceUntil — ISO timestamp when grace access ends (if applicable).

​
Usage semantics

  • Usage units represent successful subscription‑covered operations (e.g., a completed generation). They are not tokens or dollar cost.
  • Daily window resets at the next UTC day start; monthly usage aligns to the subscription billing cycle when available.
