 GitHub Copilot usage comes from `api.github.com/copilot_internal/user`, the endpoint Copilot's own editors and CLI read. The monitor uses the first GitHub login that endpoint accepts, in this order: the `COPILOT_GITHUB_TOKEN`, `GH_TOKEN`, or `GITHUB_TOKEN` environment variable, the Copilot CLI login, then the GitHub CLI login, both read from Windows Credential Manager. Copilot spends one premium-request pool per calendar month, so the monitor shows it on the long-window row and leaves the short-window row empty. Metered chat and completion allowances, as on Copilot Free, are available to themes through `copilot.limits.chat` and `copilot.limits.completions`.
 
+Mistral usage (Vibe CLI and Studio/La Plateforme) comes from `api.mistral.ai` with a Bearer API key, read from `MISTRAL_API_KEY` or from the `mistral:vibe-api-key` entry in Windows Credential Manager — the same key the Vibe CLI uses. The short-window row reads the `x-ratelimit-*` headers returned by `GET /v1/models`; the long-window row shows the calendar-month spend from `GET /v1/billing/usage` (in EUR) against the `monthly_budget` from `GET /v1/billing/subscription`, resetting at midnight UTC on the 1st, and is labelled `30d`. Billing routes that the key cannot read (403/404) are skipped without failing the poll.

 ## Data and privacy
 
 The monitor reads local sign-in credentials for enabled providers and sends usage requests directly to their official services. It has no backend service, collects no telemetry, and does not upload credentials or project files.
