dsh-balance-stats

English | 简体中文

dsh-balance-stats is a balance and usage statistics plugin for DeepSeek Harness Web. It displays three key figures in the conversation.composer.dock bar below the conversation composer:

Balance ¥40.22 | This session ¥0.15 | Total spent 42.5%

Click the bar to open an interactive, scrollable details card with balance composition, Harness local usage estimates, model-level spend, token usage, and historical billing summaries.

Quick install

Make sure Node.js >=22.19.0 is installed and pnpm --version works, then run:

npx @deepseek-ai/dsh plugin --profile web add https://github.com/pangzi499/dsh-balance-stats.git

Start or restart Harness Web, then hard-refresh the browser:

npx @deepseek-ai/dsh web

Update: npx @deepseek-ai/dsh plugin --profile web update dsh-balance-stats

Screenshots

DeepSeek Harness is still in developer preview. The client APIs and mounting slot used by this plugin may change in upstream releases.

Compatibility

• Tested with DeepSeek Harness: 0.1.0-rc.6
• Node.js: >=22.19.0
• pnpm: must be available on PATH because Harness uses it to manage profile plugins
• Tested environment: OrbStack Ubuntu with Node.js 24.19.0

This is a community plugin for DeepSeek Harness. It is not an official @deepseek-ai plugin.

Check pnpm before installing:

pnpm --version
command -v pnpm

If pnpm is missing, install it with Corepack:

corepack enable
corepack prepare pnpm@10 --activate
pnpm --version

If Corepack is unavailable in your Node.js installation, use npm:

npm install --global pnpm@10
pnpm --version

Features

• Balance: reads the official DeepSeek balance API and shows available, topped-up, and granted balances.
• This session: estimates the active conversation cost in real time through the composer-scoped balanceStatsSessionCost projection.
• Total spent: uses an accounting-based percentage after an invoice import; otherwise falls back to the Harness local estimate.
• Details card: shows spend today, over the last 7/30 days, per-model spend, token usage, and update time.
• JSON invoice import: accepts a pasted get_all_invoice JSON response to calculate historical top-ups and accounting-based total spend.
• Caching and resilience: retains the last successful balance when a request fails and refreshes server/client data on configurable intervals. The refresh button in the stats bar immediately re-fetches the balance from DeepSeek.

How figures are calculated

Balance

The server requests:

GET https://api.deepseek.com/user/balance

By default, the API key is read from the Harness credential DEEPSEEK_API_KEY. It is never sent to the browser.

Harness local estimate

The plugin scans usage events in Harness conversation logs and calculates spend from model prices using:

• Uncached input tokens
• Cache-hit/write tokens
• Output tokens
• Spend aggregated by date and model

This is a local estimate. It may exclude calls made outside Harness, deleted historical logs, or calls without standard usage events.

Historical invoices

The public DeepSeek balance API does not return historical top-ups. To enable accounting-based figures:

1. Sign in to https://platform.deepseek.com/.
2. Use browser developer tools to copy the JSON response from https://platform.deepseek.com/auth-api/v0/users/get_all_invoice.
3. Click the statistics bar below the composer.
4. Paste the complete JSON into the field at the top of the details card and click Import.

Only top-up orders where payment_order_status === "SUCCESS" are counted. Valid grant orders are accumulated separately.

Accounting total = historical top-ups + historical grants
Accounting spend = max(0, accounting total - current total balance)
Total spent = accounting spend / accounting total × 100%

Without imported invoices:

Total spent = Harness local estimated spend
              / (remaining topped-up balance + Harness local estimated spend)
              × 100%

Privacy and storage

• The plugin never requests get_all_invoice or stores DeepSeek Platform cookies.
• Pasted JSON is parsed only in the current page's memory and cleared immediately after a successful import.
• Only aggregate values—historical top-ups, grants, order count, currency, and import time—are saved in the current browser's localStorage.
• Order IDs, payment channels, and transaction details are not persisted.
• Clearing site data requires you to import the invoice summary again.

get_all_invoice is a private, authenticated DeepSeek Platform endpoint and its response format may change. Never share cookies, authorization headers, or raw JSON containing order details.

Installation

GitHub (recommended)

Install the latest version from the default branch:

npx @deepseek-ai/dsh plugin --profile web add https://github.com/pangzi499/dsh-balance-stats.git
npx @deepseek-ai/dsh web

Repository: https://github.com/pangzi499/dsh-balance-stats

You can also download dsh-balance-stats-0.1.2.tgz from the GitHub Release and install it as a tarball.

Local directory

npx @deepseek-ai/dsh plugin --profile web add /absolute/path/to/dsh-balance-stats
npx @deepseek-ai/dsh web

Tarball

Build:

cd /path/to/dsh-balance-stats
npm pack

Install:

npx @deepseek-ai/dsh plugin --profile web add /absolute/path/to/dsh-balance-stats-0.1.2.tgz
npx @deepseek-ai/dsh web

Then hard-refresh the browser (macOS: Command + Shift + R; Windows/Linux: Ctrl + Shift + R).

Updating

For GitHub one-line installs, the update command is in Quick install above.

For local-directory or tarball installations, run add again with the new path, then restart dsh web.

Configuration

Override plugin configuration in $DSH_HOME/profiles/web/cordis.patch.yml. Configuration is replaced as a whole, so repeat every key you want to retain:

- id: dsh-balance-stats
  config:
    apiKey: ''
    apiKeyRef: DEEPSEEK_API_KEY
    baseUrl: https://api.deepseek.com
    refreshIntervalMs: 300000
    clientPollIntervalMs: 30000
    timeoutMs: 8000
    currency: CNY
    prices:
      deepseek-chat: { cacheHit: 0.1, cacheMiss: 1, output: 2 }
      deepseek-reasoner: { cacheHit: 1, cacheMiss: 4, output: 16 }
    defaultPrices: { cacheHit: 0.1, cacheMiss: 1, output: 2 }

Prefer apiKeyRef so the plugin reuses Harness credentials. Never put a real API key in a cordis.patch.yml file that you plan to share.

Verification

After starting the Web profile:

curl http://127.0.0.1:3080/balance-stats
curl http://127.0.0.1:3080/plugins/dsh-balance-stats/client.js

Example statistics response (amounts are illustrative):

{
  "ok": true,
  "currency": "CNY",
  "balances": [
    { "currency": "CNY", "total": 40.22, "granted": 0, "toppedUp": 40.22 }
  ],
  "stats": {
    "state": "ok",
    "totalCost": 2.103612,
    "percent": 5,
    "today": 2.103612,
    "day7": 2.103612,
    "day30": 2.103612,
    "sessions": 10
  }
}

Known limitations

• Harness local spend is an estimate, not an official DeepSeek invoice.
• Historical invoice summaries depend on the private get_all_invoice response format.
• Invoice summaries are browser-local and do not sync across browsers or devices.
• Balance, invoice, and estimated-price currencies must match.
• Upstream changes to DSH client slots or projection APIs may require plugin updates.

Uninstall

npx @deepseek-ai/dsh plugin --profile web remove dsh-balance-stats
