DSH DeepSeek Balance Plugin

English | 简体中文

English

A DeepSeek Harness Web client plugin that adds a DeepSeek Balance tab to the Web settings plugin area. It shows the live DeepSeek API balance from the official /user/balance endpoint, a local balance trend, and daily cost / token usage charts powered by ECharts.

API reference: https://api-docs.deepseek.com/zh-cn/api/get-user-balance

Features

• Live balance: calls GET https://api.deepseek.com/user/balance with Authorization: Bearer <API key>, shows is_available and every balance_infos entry (currency, total_balance, granted_balance, topped_up_balance). Refreshes on demand and every 60 seconds.
• Balance trend: every successful balance read records one point per day in localStorage; a line chart appears once two points exist.
• Collapsible sections: live balance, trend, and daily usage blocks can be collapsed/expanded; the state is remembered per browser.
• Floating window: a draggable, always-on-top mini window shows the latest balance, availability, and a sparkline. Toggle it from the tab header; position and visibility persist.
• Daily usage (optional): paste your DeepSeek Platform userToken (from platform.deepseek.com DevTools → Local Storage) and pick a range (7 days / 30 days / this month / last month). The plugin fetches the private Platform usage endpoints through a same-origin host proxy and renders:
  • a bar + line chart of daily cost and daily tokens (ECharts, loaded from CDN),
  • summary stats: total cost, request count, input/output/cached tokens, cache hit rate.
• Keys: the API key and the Platform userToken are both stored in the browser's localStorage (keys dsh-plugin-deepseek-balance.apiKey / ...platformToken) so they survive reloads; a "Clear token" button removes the Platform token.

Security

• The API key is stored in the current browser's localStorage and is sent only to https://api.deepseek.com.
• The Platform userToken is a full session credential. It is persisted in the browser's localStorage (same trust domain as the API key) and is only POSTed to the plugin's same-origin host endpoint (POST /api/dsh-deepseek-balance/usage), which forwards it to platform.deepseek.com with browser-like headers and returns only the normalized usage data. Nothing is written to disk on the host side.
• The daily-usage feature relies on undocumented private Platform endpoints and the WAF may rate-limit or block requests; failures surface as clear error messages.

Build

npm ci
npm run bundle

bundle runs tsdown and then scripts/wrap-client.mjs, which converts the ESM client output into the DSH Web client-loader format (window.__ModuleLoader__.load({ id, factory })) required by the browser-side module system. The host entry (lib/index.js) stays plain ESM and registers the usage proxy through ctx.webServer.

The package metadata declares the DSH Web client entry at ./client. Enable the built package through the Harness plugin loader or composition, following the same mechanism as other DSH Web client plugins.

Project Files

• src/index.ts: Host half — same-origin usage proxy via ctx.webServer (no token persistence).
• src/client.tsx: Settings tab: balance, balance trend, daily usage, ECharts rendering.
• scripts/wrap-client.mjs: Post-build wrap into the DSH client-loader format.
• package.json: DSH client plugin metadata.
• .github/workflows/ci.yml: GitHub Actions build verification.

简体中文

这是一个 DeepSeek Harness Web 客户端插件。它会在 Web 设置的插件区域新增 DeepSeek 余额 标签页：显示官方 /user/balance 接口的实时余额、本地余额趋势，以及基于 ECharts 的每日消耗 / Token 用量图表。

API 文档： https://api-docs.deepseek.com/zh-cn/api/get-user-balance

功能

• 实时余额：使用 Authorization: Bearer <API Key> 调用 GET https://api.deepseek.com/user/balance，展示 is_available 与全部 balance_infos 条目（currency、total_balance、granted_balance、topped_up_balance）。支持手动刷新与每 60 秒自动刷新。
• 余额趋势：每次成功读取余额后在 localStorage 记录一个数据点（每天一个）；积累两个点后显示折线图。
• 可折叠区块：实时余额、余额趋势、每日用量三块均可展开 / 折叠，状态按浏览器记忆。
• 悬浮窗：可拖拽、置顶的迷你窗口，显示最新余额、账户可用状态与余额走势（SVG 迷你图）。可在标签页头部切换显示；位置与可见性会持久化。
• 每日用量（可选）：粘贴 DeepSeek 开放平台 的 userToken（登录 platform.deepseek.com 后 F12 → Application → Local Storage 复制），选择范围（近 7 天 / 近 30 天 / 本月 / 上月）。插件通过同源 host 代理调用平台私有用量接口并渲染：
  • 每日消耗柱状图 + 每日 Token 折线图（ECharts，从 CDN 加载）；
  • 汇总统计：总消耗、请求数、输入 / 输出 / 缓存 Token、缓存命中率。
• 密钥处理：API Key 与 Platform userToken 都保存在浏览器 localStorage（键 dsh-plugin-deepseek-balance.apiKey / ...platformToken），刷新页面后仍在；提供「清除 Token」按钮。

安全说明

• API Key 保存在当前浏览器 localStorage，仅发送到 https://api.deepseek.com。
• Platform userToken 是完整会话凭据。它持久化在浏览器 localStorage（与 API Key 同一信任域），只 POST 到插件的同源 host 端点（POST /api/dsh-deepseek-balance/usage），由 host 带浏览器特征头转发到 platform.deepseek.com，仅返回规范化后的用量数据；host 侧不写入磁盘。
• 每日用量依赖未公开的平台私有接口，WAF 可能限流或拦截；失败时会显示明确错误信息。

构建

npm ci
npm run bundle

bundle 先执行 tsdown，再运行 scripts/wrap-client.mjs，将 ESM 客户端产物转换为 DSH Web 客户端加载器格式（window.__ModuleLoader__.load({ id, factory })），这是浏览器端模块系统要求的格式。host 入口（lib/index.js）保持普通 ESM，并通过 ctx.webServer 注册用量代理。

包元数据已声明 DSH Web 客户端入口 ./client。构建完成后，请按 DSH 其他 Web 客户端插件相同的方式，通过 Harness 插件 loader 或 composition 启用此包。

项目文件

• src/index.ts：Host 半侧 — 基于 ctx.webServer 的同源用量代理（不持久化 token）。
• src/client.tsx：设置页标签：余额、余额趋势、每日用量、ECharts 渲染。
• scripts/wrap-client.mjs：构建后转换为 DSH 客户端加载器格式。
• package.json：DSH 客户端插件元数据。
• .github/workflows/ci.yml：GitHub Actions 构建校验。
