dsh-model-balance

Auto-detect the current model vendor and show its balance / quota right in the composer input row — a small button left of the model name, hover to peek, click to refresh. A settings page covers vendors without a public balance endpoint via custom endpoints.

Built for DeepSeek Harness (DSH web).

Features

• Auto vendor detection — reads the current default model's provider from DSH configuration and identifies the vendor by provider id, then by baseURL hostname as a fallback. Custom provider ids (e.g. minimax-cn) still match.
• Built-in vendors — DeepSeek, Moonshot/Kimi, MiniMax, StepFun, Zhipu (quota only), SiliconFlow, OpenRouter.
• Two result kinds — monetary balance (with granted/topped-up breakdown where the API provides it) and quota (MiniMax / Zhipu, which expose usage plans instead of money).
• Input-row button — a small ◈ icon before the model name in the native composer row. Hover opens a peek panel; click refreshes. Error / unsupported / quota states get their own colors.
• Settings page — Settings → 余额查询: lists supported vendors and lets you add a custom balance endpoint for any provider (URL + response field path + bearer/raw auth + display name).
• Key-safe — API keys are resolved host-side through the DSH credentials store and never reach the browser. Custom endpoint config persists at ~/.dsh/dsh-model-balance.json without any secrets.
• Live in seconds — the host answers over same-origin HTTP routes; no restart needed after a page refresh.

Install

Requires DSH web. From the plugin market or:

# from GitHub
dsh plugin --profile web add github:jacujay/dsh-model-balance

Then refresh the browser page.

Supported vendors

Vendor	Endpoint	Kind
DeepSeek	/user/balance	balance (CNY)
Moonshot / Kimi	/v1/users/me/balance	balance
MiniMax	/v1/token_plan/remains	quota (per-model %)
StepFun	/v1/accounts	balance
Zhipu GLM	/api/monitor/usage/quota/limit	quota only
SiliconFlow	/v1/user/info	balance
OpenRouter	/api/v1/auth/key	balance (USD) / unlimited

Anything else: add a custom endpoint in Settings → 余额查询. The API key still comes from DSH credentials (apiKeyEnv of the provider), the custom URL is called host-side with it.

Privacy & security notes

• Balance requests are issued by the local DSH host with the provider's API key; the key never leaves this machine and never enters the browser.
• The settings page stores only endpoint metadata (~/.dsh/dsh-model-balance.json), no secrets.
• The host routes are same-origin HTTP on the existing DSH web server; mutating routes (custom endpoint save/delete) carry a same-origin check.
• Custom endpoint URLs are user-provided and may point anywhere; review them before saving.

Development

# no build step — host is plain ESM (lib/index.js), client is a plain
# __ModuleLoader__ bundle (client/client.js)
node --check lib/index.js
node --check client/client.js
