balance-show

When calling the DeepSeek API in day-to-day development, it is easy to lose track of what remains in your account balance, how many tokens the current conversation has burned through, how well caching is working, and what the actual cost comes to once peak-and-off-peak pricing is applied. balance-show folds all of these signals into a single floating card pinned to the bottom-right corner of your browser, so you can check spend at a glance without ever leaving your editor.

The card shows the balance digit colour-coded by tier (green for healthy, orange for getting low, red for critical), real-time token usage and cache-hit rate for the active session, and a per-message cost estimated locally against DeepSeek official pricing schedules, including the 2026 off-peak half-price windows (peaks at 09:00-12:00 and 14:00-18:00, everything else half price). Everything runs inside the harness with zero third-party runtime dependencies, and it always reads the account tied to the locally configured API key, so you see your own numbers and nothing else.

This plugin is built for developers who have an API key set up in DeepSeek Harness and make high-volume calls throughout the day. Between lines of code, a quick glance at the corner card tells you whether today budget is still in range and whether your caching strategy is actually paying off, without opening a dashboard or digging through billing pages.
