Live ticker

When your app is running with burn0 imported, a live cost ticker appears on stderr:

  burn0 ▸ $4.32 today (47 calls) ── openai: $3.80 · anthropic: $0.52

This updates in-place as API calls happen. It doesn’t interfere with your app’s stdout output. When the process exits, a session summary is printed:

  burn0 ▸ session: $0.47 (12 calls, 4m 22s) ── today: $14.32 ── ~$430/mo
