DeepSeek Balance Checker

View your DeepSeek API account balance at a glance with badge display

DeepSeek Balance Checker lets you monitor your DeepSeek API account balance directly from the Chrome toolbar — no need to open the dashboard. Your API key is never uploaded — it stays on your device and is only sent to the official DeepSeek API to fetch your balance. No API calls incur any charges, so feel free to configure it with confidence. FEATURES - Badge Display: Your balance is shown right on the extension icon, color-coded green (sufficient) or red (low/unavailable). - Smart Formatting: Large balances are automatically shortened to fit the badge (e.g., 12K, 3.5K, 570). - Detailed Popup: Click the icon to see a full breakdown — total balance, granted balance, and topped-up balance. - Multi-Currency: Supports both CNY and USD display. - Auto Refresh: Configurable refresh interval (default: 30 minutes) keeps your balance up to date. - Manual Refresh: One-click refresh from the popup. - Connection Test: Verify your API Key works before saving. - Privacy First: Your API Key is stored locally on your device and only sent to the official DeepSeek API endpoint. No data is collected or shared. HOW TO USE 1. Install the extension. 2. Right-click the extension icon → Options (or click the gear icon in the popup). 3. Enter your DeepSeek API Key (get one at https://platform.deepseek.com/api_keys). 4. Choose your currency and refresh interval. 5. Click "Save" — your balance appears on the badge immediately. PERMISSIONS - Storage: Save your API Key and preferences locally. - Alarms: Schedule periodic balance checks. - api.deepseek.com: Fetch your account balance via the official API.
