Questions you should be asking.
Is it safe to paste my admin key?+
Admin keys are read-only for usage and cost data — they cannot run inference or read your prompts, by OpenAI's and Anthropic's own design. We encrypt them at rest and never expose them client-side. Revoke the key any time and Burnline loses all access instantly.
Can you see my prompts or outputs?+
No, and we couldn't even if we wanted to. The APIs we use return usage metadata and cost only.
How fresh is the data?+
Providers publish usage data within about five minutes. We poll as often as each provider allows and stamp every view with its last-updated time.
Do I need to change my code?+
No. No SDK, no proxy, no wrapper. Paste a key, done.
What if my key breaks or expires?+
You'll know. Connection health is monitored continuously and we alert you the moment polling fails.
What happens if I cancel?+
Free stays free forever. Your data exports any time. No lock-in theatrics.
