Key limit - concentrate

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

Setting	What it does
Threshold Percentage	Percentage 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.
