$2,100. Gone.
In one night. While I was sleeping.
The agent had hit an edge case, entered a loop, and just kept calling the API. Over and over. For hours.
No alert. No warning. No stop.

It's a proxy. Sits between your code and your API keys. Set a daily limit. At 80% you get a Telegram + email alert. At 100% it hard blocks the request and kills the loop.

I'm calling it BurnStop.
Works with Anthropic and OpenRouter today.
If you've ever shipped an autonomous agent and thought "I hope nothing goes wrong tonight" — this is for you.
Waitlist is open. No pitch. No pressure.

It's not glamorous.
It's not AI-powered irony or a 10x productivity tool.
It's a circuit breaker. For your wallet.
The thing I wish existed the night my agent ran wild.
So I did what any broke founder does.
I stopped sleeping on it and started building.
A simple proxy. Sits between your code and the API.
You set a daily limit. We watch every call. At 80% you get a Telegram message. At 100% — hard block. Request denied. Loop killed.
I started looking for a tool to prevent this.
Helicone — great for traces, won't stop a loop in real time.
OpenAI has spend limits — hours of latency, useless for live agents.
Anthropic had nothing.
I was building on the most powerful models with zero financial protection.
Anthropic support.
They were polite. They explained their policy.
I understood. But understanding doesn't pay the bill.
That $2,100 was my runway for the month.
It was 2am. I had just shipped a new autonomous agent.
Went to sleep feeling good. First time in weeks I actually slept well.
Woke up to an email from my bank. Not Anthropic. My bank.
"Unusual charge detected."
I almost shut down my startup because of an API bill.
Not because the product failed. Not because I ran out of runway.
Because an agent looped overnight and I didn't know until morning. @AnthropicAI@OpenRouter
