Fusebox: Spend-ceiling alerts for solo OpenAI API users

Hey, maker here. I kept seeing people get blindsided by OpenAI bills - a retry loop left running overnight, or a demo link shared wider than intended. Team observability tools exist, but they're built for a finance meeting, not a hobbyist who just wants a heads-up before $12 becomes $300. Before writing any code, I checked what kind of access key I'd actually need. OpenAI lets you scope an Admin key to exactly api.usage.read and nothing else - genuinely safe to hand to a third-party tool. I checked the same thing for Claude and Anthropic's Console admin keys are currently all-or-nothing for individual accounts, so Claude support is on hold until that changes - wrote up the full story at /story on the site if you're curious. Would love feedback, especially on whether the OpenAI-only limitation is a dealbreaker for people here.
