dougen/dsh-deepseek-usage

中文文档

A sidebar plugin for the DeepSeek Harness (DSH) Web UI that answers two questions without leaving the app: how much balance is left, and what the model costs right now — the second one for official DeepSeek models, whose prices the built-in table and DeepSeek's peak/off-peak windows cover.

What it does

• Balance in the sidebar footer: your DeepSeek account balance (the symbol follows the account currency: ¥ / $).
• Unit prices of the active model: input / input cache / output for the billing window in effect right now. They change when you switch models and when the peak/off-peak window flips.
• Peak / off-peak dot with a countdown: orange during peak hours (Mon–Fri, excluding Chinese public holidays, 9:00–12:00 and 14:00–18:00 Beijing Time), green otherwise — weekends, public holidays and the make-up workdays that fall on a weekend are all off-peak; next to it, the time left until the next switch (2d 15h, 5h 47m, 23m).
• Unit prices and the peak/off-peak dot are for official DeepSeek models only. When the active model is not one of them (a third-party provider's model, or a router that reports the provider name as the model), the card shows the balance alone: the built-in price table and DeepSeek's peak/off-peak windows do not apply, so any figure derived from them would not match your bill.
• Refreshes every 30 seconds, and immediately when you click the card or switch models. Follows the app light/dark theme and the DSH language (Chinese / English).

DSH compatibility

DSH	Plugin version
0.2.x (0.2.0-rc.1 and later)	0.11.0 and later
0.1.x (0.1.0-rc.6 and later)	0.10.x, or 0.11.0 and later

dsh --version prints your DSH version. Installing without a version picks the newest compatible release; name an exact version (@dougen/dsh-deepseek-usage@0.10.2) when the newest does not match your DSH.

Install, uninstall, common errors

Install

1. Configure DEEPSEEK_API_KEY in DSH (model settings).
2. dsh plugin --profile web add @dougen/dsh-deepseek-usage
3. Restart dsh web and open the URL it prints — the card sits at the bottom of the sidebar, below the Cordis panel button.

Uninstall

dsh plugin --profile web remove @dougen/dsh-deepseek-usage

Then restart dsh web.

A blank card means the balance could not be read

The card then shows the reason instead of numbers:

• DEEPSEEK_API_KEY is not configured — set it in DSH settings and restart.
• The balance request or the network failed — click the card to retry.
• DEEPSEEK_BASE_URL points at a third-party gateway — the official balance endpoint https://api.deepseek.com/user/balance may be unavailable or answer differently; only DeepSeek's official platform is supported.

Prices differ from the official page

• Prices are the built-in table PRICE_TABLE in lib/pricing.js, a snapshot of the official pricing page. It changes only when a new version of the plugin ships — there is no local price file and no background sync.
• The card only shows unit prices and the peak/off-peak dot when the active model is an official DeepSeek model (deepseek-flash, deepseek-v4-pro, deepseek-chat, deepseek-reasoner and the legacy names). Any other model — a third-party provider's, or a router reporting the provider name as the model — has no official peak/off-peak pricing, so the card hides both instead of showing a figure that would not match your bill.
• An official model newer than this plugin release is not in the table either, and the card hides prices for it until the table is updated.
• Off-peak days come from the holiday table HOLIDAY_RANGES in lib/pricing.js. The State Council usually publishes next year's arrangement in November; update it then. Until you do, holidays are treated as ordinary workdays and the card shows peak prices during them.

How it works

• The host half (lib/index.js, lib/pricing.js) registers GET /api/deepseek-usage. Per request it reads the API key from DSH credentials, asks the official balance API, resolves the active model's price from the built-in price table, and answers with balance, tier prices, the peak flag and the next switch time. GET /api/deepseek-usage/holidays hands the browser half the same public-holiday table.
• The browser half (lib/client.js) renders that answer into the sidebar.footer.action slot, re-reads it every 30 seconds, and refreshes on click or on a model change. The peak state and the countdown come from the same answer, so the card itself holds no pricing logic.

一个 DeepSeek Harness（DSH）网页界面的侧边栏插件：不离开 DSH 就能知道账号还剩多少钱；当前用的是 DeepSeek 官方模型时，还能看到它现在什么价——内置价格表与官方峰谷时段覆盖的正是这些模型。

这个插件做什么

• 余额：侧边栏底部显示 DeepSeek 账号余额（符号随账号币种 ¥ / $）。
• 当前模型的档单价：输入 / 输入缓存 / 输出，按此刻生效的计费时段显示；切换模型、跨过峰谷切换点时会跟着变。
• 峰谷指示灯 + 倒计时：高峰（周一至周五、不含中国法定节假日，9:00–12:00、14:00–18:00 北京时间）橙色，其余时间绿色——周末、法定节假日全天，以及调休上班的周末都是空闲；指示灯旁给出距下次切换的剩余时间（2d 15h、5h 47m、23m）。
• 档单价与峰谷指示灯只对 DeepSeek 官方模型显示。当前模型不是官方模型时（第三方供应商的模型，或路由器把供应商名当模型名上报），卡片只显示余额：内置价格表与官方峰谷时段对它不成立，据此算出的数字与实际账单不符。
• 每 30 秒自动刷新；点击卡片或切换模型时立即刷新。跟随应用明暗主题与 DSH 语言（中文 / English）。

DSH 版本对应关系

DSH	插件版本
0.2.x（0.2.0-rc.1 起）	0.11.0 及以后
0.1.x（0.1.0-rc.6 起）	0.10.x，或 0.11.0 及以后

dsh --version 查看当前 DSH 版本。不带版本号安装会取最新的兼容版本；最新版与你的 DSH 不匹配时，用 @dougen/dsh-deepseek-usage@0.10.2 这样的完整版本号指定。

安装、卸载与常见错误

安装：

1. 在 DSH 设置（模型页）里配置 DEEPSEEK_API_KEY。
2. dsh plugin --profile web add @dougen/dsh-deepseek-usage
3. 重启 dsh web，打开它打印的地址：卡片位于侧边栏底部、Cordis 面板按钮下方。

卸载：

dsh plugin --profile web remove @dougen/dsh-deepseek-usage

然后重启 dsh web。

卡片空白说明余额没读到，此时卡片会写明原因：

• 没有配置 DEEPSEEK_API_KEY：在 DSH 设置里配置后重启。
• 余额接口或网络失败：点击卡片重试。
• DEEPSEEK_BASE_URL 指向第三方中转：官方余额接口 https://api.deepseek.com/user/balance 可能不可用或返回异常，本插件只支持 DeepSeek 官方平台。

价格与官方不一致时：

• 价格是 lib/pricing.js 的内置表 PRICE_TABLE（官方价格页的快照），只在发布新版本时更新——没有本地价格文件，也没有后台同步。
• 只有当前模型是 DeepSeek 官方模型（deepseek-flash、deepseek-v4-pro、deepseek-chat、deepseek-reasoner 及旧名）时，卡片才显示档单价与峰谷指示灯；其他模型（第三方供应商的模型、路由器把供应商名当模型名上报）没有官方峰谷定价，卡片把这两项都隐藏，而不是显示一个与实际账单不符的数字。
• 比本插件版本更新的官方模型同样不在表里，卡片会隐藏价格，直到价格表更新。
• 放假日期维护在 lib/pricing.js 的 HOLIDAY_RANGES。国务院办公厅通常在前一年 11 月发布次年安排，届时更新；未更新前，节假日会按普通工作日处理，白天显示高峰价。

简单的工作原理

• 宿主侧（lib/index.js、lib/pricing.js）注册 GET /api/deepseek-usage：每次请求读取 DSH 凭据里的 API Key、调用官方余额接口、从内置价格表解析当前模型档单价，返回余额、档单价、峰谷状态与下次切换时刻；GET /api/deepseek-usage/holidays 把同一份法定节假日表交给浏览器侧。
• 浏览器侧（lib/client.js）把这份响应渲染进 sidebar.footer.action 槽位，每 30 秒重新读一次，点击卡片或模型变化时立即刷新；峰谷状态与倒计时同样来自这次响应，界面自身不做计价逻辑。
