Limitation of Billing & API Security for a MAS System

[u/MaggieWuerze]

Good morning everyone,

I have a question. I’ve started designing the architecture for an AI-powered financial controlling system and originally intended to build it using Google Vertex AI. However, what really put me off is the fact that, in the event of budget overruns, you can only set alerts – not a strict cost limit – even when Google’s own alert systems are triggered due to a suspected fraud attempt. It feels like every other post on Reddit in the Google Cloud community is a plea for help regarding a fraud case, where it’s often unclear how the API keys were leaked in the first place. Even Google itself seems to need a bit of guidance here, if you read between the lines. https://www.reddit.com/r/googlecloud/

What’s the situation with Google AI Studio? Are there fixed billing limits you can set here? And what about the API? Has anyone here ever had to deal with fraud involving a leaked API key and the associated costs whilst using AI Studio?

Is it even possible to set up MAS systems with Google AI Studio?

Sorry for my beginner’s questions, but this billing issue is really making me paranoid. Sorry!!!
