 ## Unreleased
 
+### Command Code provider
+
+- New **Command Code** (commandcode.ai) provider surfaces the live 5-hour and weekly usage windows plus the monthly USD credit balance via the same Provider API key used for the CLI (`COMMAND_CODE_API_KEY`). The `/alpha/billing/` endpoints are experimental, so the adapter degrades to the documented `/provider/v1/models` auth-only check on alpha failure — never a fabricated percentage. Contributed by [@Luna161](https://github.com/Luna161) ([#20](https://github.com/bernardopg/AiOverviewControl/issues/20), [#21](https://github.com/bernardopg/AiOverviewControl/pull/21)).

+| **Billing** | Per-token, no markup on the Provider plan. Credits roll over and never expire. Window caps are USD ceilings — model deals (e.g. `minimax-m3` 2×, `google/gemini-3.7-flash` 50% off, `mimo-v2.5-pro` 99% off) apply automatically. |
+| **Stability** | The `/alpha/` namespace is **experimental** — no documented versioned contract, can change without notice. Adapter degrades to the documented `/provider/v1/models` endpoint on alpha failure and emits a clearly-labeled "quota endpoint unavailable" note; it never fabricates a percentage. |
+| **Dashboard** | [commandcode.ai/billing](https://commandcode.ai/billing) — billing, plan, and credit top-ups. |
+| **Adapter** | `fetch_commandcode_native` — `/alpha/billing/credits` + `/alpha/whoami` + `/alpha/billing/subscriptions`, with documented-endpoint fallback. |
