+# Usage Tracking
+
+# 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.
+* CLI: `openclaw status --usage` prints a full per-provider breakdown.
+* CLI: `openclaw channels list` prints the same usage snapshot alongside provider config (use `--no-usage` to skip).
+* macOS menu bar: “Usage” section under Context (only if available).
+
+## Providers + credentials
+
+* **Anthropic (Claude)**: OAuth tokens in auth profiles.
+* **GitHub Copilot**: OAuth tokens in auth profiles.
+* **Gemini CLI**: OAuth tokens in auth profiles.
+* **Antigravity**: OAuth tokens in auth profiles.
+* **OpenAI Codex**: OAuth tokens in auth profiles (accountId used when present).
+* **MiniMax**: API key (coding plan key; `MINIMAX_CODE_PLAN_KEY` or `MINIMAX_API_KEY`); uses the 5‑hour coding plan window.
+* **z.ai**: API key via env/config/auth store.
+
+Usage is hidden if no matching OAuth/API credentials exist.
