Key limit alerts you the moment a key’s usage crosses a percentage of its period limit. Unlike key exhaustion — which forecasts ahead — key limit is reactive and fires as soon as the threshold is actually hit.

​
When to use it

  • You want to know the instant a key crosses, say, 80% or 90% of its cap.
  • A safety net under key exhaustion — the forecast misses sometimes, the threshold doesn’t.
  • Keys with predictable, steady usage where a flat percentage is the most natural signal.
Keys without a period limit are skipped — there’s nothing to measure against. Set a period limit on the key first.

​
What you configure

SettingWhat it does
Threshold PercentagePercentage of the period limit at which the alert fires (e.g. 80 for 80%).
This is a reactive alert — no schedule, no scope picker. It evaluates each time the key is used.

​
How you’re notified

Email and/or SMS, based on your preferences in Settings → Notifications. A cooldown prevents repeat notifications while the key stays above the threshold. See the alerts overview for delivery details.
