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 a 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

Details card — click the bar to open it: balance composition, billing history, per-model spend, token usage, and the invoice import field:

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.
• Auto invoice import (optional): paste your platform userToken once in the details card and the server re-fetches invoices on a schedule; the token persists to the local credentials file (mode 0600), survives restarts, and clears with one click.
• JSON invoice import (fallback): without a token, paste a get_all_invoice JSON response for a one-shot import. Importing force-refreshes the balance, so every figure updates at once.
• Caching and resilience: retains the last successful balance/invoice when a request fails (stale-while-error) and refreshes server/client data on configurable intervals. The refresh button in the stats bar immediately re-fetches from DeepSeek.

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.

prices applies to ordinary models and v4 usage before 2026-08-17 00:00 +08:00. After that cutoff, v4 usage selects v4PeakPrices during 09:00–12:00 and 14:00–18:00 Beijing time, and v4OffPeakPrices at other times. All three price maps are configurable.

Historical invoices

The public DeepSeek balance API does not return historical top-ups. To enable accounting-based figures, pick one of three ways:

Option 1 — auto import (recommended)

1. Click the stats bar to open the details card and expand "Auto invoice import".
2. Follow the 3-step guide: sign in to the platform → run copy(localStorage.userToken) in the console → come back, paste it, and press Save.
3. Saving verifies the token with one live fetch, then persists it to the local credentials file ~/.dsh/.credentials.yaml (mode 0600). The plugin re-fetches invoices every invoiceRefreshIntervalMs (default 6 hours) and restores the token automatically after restarting dsh web.
4. An expired session turns the status dot amber ("Expired"); paste a fresh token to resume. "Clear" removes everything again.

Option 2 — manual JSON paste (no token)

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. Open the details card, expand "Advanced", paste the complete JSON, and click Import.

Option 3 — environment / config

Store the token under the Harness credential DEEPSEEK_PLATFORM_TOKEN (or platformToken in cordis.patch.yml, or an env var of that name); auto import starts on launch.

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
              / (current total balance + Harness local estimated spend)
              × 100%

• By default (no token provided), the plugin never requests get_all_invoice and stores no DeepSeek Platform credentials.
• Only when you explicitly paste a userToken and press Save does the plugin call the invoice endpoint with it and write the token to the local Harness credentials file ~/.dsh/.credentials.yaml (mode 0600, managed by the Harness credentials provider). "Clear" in the card removes it again.
• No DeepSeek Platform cookies are accepted or stored; the token never leaves your machine except to platform.deepseek.com.
• Manually pasted JSON is parsed only in memory. The browser-side localStorage fallback summary keeps only aggregates: historical top-ups, grants, order count, currency, and import time. Order IDs, payment channels, and transaction details are not persisted.
• Signing out of the DeepSeek Platform immediately invalidates any saved token.

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

Requirements

• DeepSeek Harness: tested on 0.1.0-rc.6 through 0.1.1-rc.1
• Node.js: >=22.19.0
• pnpm: must be available on PATH because Harness uses it to manage profile plugins (missing? see Installation)
• Tested environment: OrbStack Ubuntu with Node.js 24.19.0

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

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

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-0.2.0.tgz from the GitHub Release and install it as a tarball.

Harness manages profile plugins with pnpm. Check it 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

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-0.2.0.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.

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
    platformToken: ''
    platformTokenRef: DEEPSEEK_PLATFORM_TOKEN
    invoiceRefreshIntervalMs: 21600000
    platformBaseUrl: https://platform.deepseek.com
    prices:
      deepseek-chat: { cacheHit: 0.1, cacheMiss: 1, output: 2 }
      deepseek-reasoner: { cacheHit: 1, cacheMiss: 4, output: 16 }
      deepseek-v4-flash: { cacheHit: 0.02, cacheMiss: 0.1, output: 0.2 }
      deepseek-v4-pro: { cacheHit: 0.025, cacheMiss: 3, output: 6 }
    v4PeakPrices:
      deepseek-v4-flash: { cacheHit: 0.10, cacheMiss: 3.0, output: 9.0 }
      deepseek-v4-pro: { cacheHit: 0.30, cacheMiss: 9.0, output: 27.0 }
    v4OffPeakPrices:
      deepseek-v4-flash: { cacheHit: 0.05, cacheMiss: 1.5, output: 4.5 }
      deepseek-v4-pro: { cacheHit: 0.15, cacheMiss: 4.5, output: 13.5 }
    defaultPrices: { cacheHit: 0.1, cacheMiss: 1, output: 2 }

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

Auto import keys:

• platformToken: literal platform token (plaintext; not recommended — prefer saving via the UI or credentials)
• platformTokenRef: credential reference name (default DEEPSEEK_PLATFORM_TOKEN; saving in the UI writes this credential entry)
• invoiceRefreshIntervalMs: invoice refresh interval, default 21600000 (6 h), minimum 600000
• platformBaseUrl: DeepSeek Platform base URL; normally leave as default

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.
• The platform userToken expires when you sign out of the DeepSeek Platform; paste a fresh one to resume auto import.
• Manual JSON summaries are browser-local and do not sync across browsers or devices (auto-imported summaries live on the server side).
• 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
