Use case

AI agent for SaaS and API credits

OpenAI, AWS, Anthropic, Stripe — your agent tops up credits automatically to avoid service interruptions. An infinite loop in the code can trigger 20 top-ups in one hour.

The underestimated risk

Platforms like OpenAI or AWS have no default limit on top-up frequency. If your agent enters a loop — for example because it doesn't correctly detect the new balance after a top-up — it can charge your card ten, twenty times in minutes. Incidents of this type have cost thousands of euros to solopreneurs and startups.
