About Fusebox

Fusebox provides a monthly spend ceiling for OpenAI API keys to prevent unexpected costs. The tool monitors usage and sends email alerts at 50%, 80%, and 100% of the set limit, protecting developers from high bills caused by retry loops or leaked keys.

Asking only for an OpenAI Admin key limited to api.usage.read, and explaining that it cannot spend money or manage members, removes the main worry about handing a key to a spend monitor. Email alerts at 50, 80 and 100 percent of a monthly ceiling are simple and useful. The listing shows freemium from $7, but the website offers a $29 one-time plan; which one is current?

Built this after almost getting burned by a retry loop on the OpenAI API. Free tier warns at 100% of your ceiling, paid tier adds 50%/80% early warnings. Feedback welcome!
