Never get surprised by a bill.

Set a spend cap once. MeterCall warns you at 80%, shuts off calls at 100%, and pages whoever you tell it to. No runaway agents, no 5-figure Monday mornings.

Alert types Stack them. Combine them. All real-time at the meter.

$

Daily spend cap

Hard ceiling across the entire workspace. Resets at midnight UTC.

M

Per-module cap

Limit a single module's spend. Useful for expensive AI calls.

A

Per-agent cap

Tie a cap to an agt_* ID. Rogue agent? It trips its own fuse.

80

80% warning

Soft notify when any cap crosses 80%. Just a heads-up.

X

Overage cutoff

At 100% we return HTTP 429 until you top up or raise the cap.

Anomaly spike

ML-detected 10x spike vs your rolling baseline. Catches runaway loops.

Notification channels One alert, many destinations. Deliver with retry + dedupe.
