Autonomous AI agents can enter infinite tool-calling loops; deploy hard budget ceilings and circuit breakers to stop unexpected telephony billing spikes.
When autonomous AI agents are equipped with tools that incur real-world costs (such as provisioning phone numbers or dispatching SMS messages), an unhandled error or ambiguous prompt can trigger an infinite execution loop. Implementing strict budget gates is essential.
1 Three-Tier Safety Circuit Breaker
1. Daily Hard Dollar Cap: Terminate API key execution when daily spend reaches a pre-configured threshold (e.g. $25/day).
2. Loop Velocity Throttle: If an agent calls the same tool more than 5 times in 60 seconds with identical parameters, force a 10-minute cooldown.
3. Human-in-the-Loop Escalation: Require explicit human approval before provisioning dedicated phone trunks or scaling concurrency.

Yes. All developer API accounts operate under hard tier quotas and spending ceilings with real-time webhook spike notifications to prevent billing overruns.
