 # Usage tracking
 
 ## What it is
+
 - Pulls provider usage/quota directly from their usage endpoints.
 - No estimated costs; only the provider-reported windows.
 
 ## Where it shows up
+
 - `/status` in chats: emoji‑rich status card with session tokens + estimated cost (API key only). Provider usage shows for the **current model provider** when available.
 - `/usage off|tokens|full` in chats: per-response usage footer (OAuth shows tokens only).
 - `/usage cost` in chats: local cost summary aggregated from OpenClaw session logs.
