DeepSeek account balance capsule in the conversation session header. A same-origin route registered by the package's own host half resolves the API key from the credential service and calls api.deepseek.com/user/balance, so the key never reaches the page; the capsule polls every 60 seconds and expands into a panel with per-currency totals, granted and topped-up amounts, last-updated time and a manual refresh. Read-only UI: it never touches prompts, tool results or model traffic.
