What is the “My AI agent burned $4,200 overnight repeating one broken action while I slept.” problem in 2026?
Autonomous agents retry failing steps in a loop with no spend circuit-breaker, and the first time you find out is the invoice.
Who has this problem?
Solo devs and small teams shipping LLM agents on metered APIs.
Evidence this problem is real
“The agent looped a failing tool call all night and the bill was four figures before anyone woke up.”
Existing players in this space
- Helicone / Langfuse: Observe spend after the fact; weak real-time hard caps.
- OpenAI usage limits: Monthly caps, not per-run kill-switches.
- Cloud budget alerts: Alert after the burn, do not stop the loop.
What existing players are missing
A per-run, per-agent spend circuit-breaker that kills a runaway loop mid-execution the moment cost-velocity spikes, not a dashboard you read the next morning.
