What it may solve
Tokenrhythm (基元律动) finance dashboard for DeepSeek Harness: a sidebar entry with the brand mark opens a draggable panel. The Models tab filters the gateway model list by category (text / image / audio / video / embedding) and shows model ID, upstream source, platform status (online / testing), context window, supported modalities, input / output / cache pricing with discounted prices and per-image price; a per-card connectivity dot runs a real 1-token inference check (60 s cache, ~¥0.0004). The Balance tab shows the account balance, expiring quota with countdown and share bar, frozen amount, today's usage aggregated from call logs and a 7-day cost chart with per-model hover details, auto-refreshing every 60 s, with per-account data isolation. The Keys tab lists / creates platform API keys (masked). Balance queries work via platform account login or a pasted tr_session cookie; credentials stay host-side and the browser only ever sees masks.
