Glm Quota

OpenCode plugin to query Z.ai GLM Coding Plan usage statistics with real-time quota monitoring, model usage tracking, and MCP tool usage.

Features

• 📊 Query current quota limits (5-hour token cycle, weekly quota, monthly MCP usage)
• 🤖 View model usage statistics (24-hour rolling window)
• 🔧 View MCP tool usage (web_search, web_reader, etc.)
• 🌍 Supports both Global (api.z.ai) and CN (open.bigmodel.cn) platforms
• 🔐 Automatic credential discovery via OpenCode authentication context
• 📈 Visual progress bars for quota percentages rendered in Markdown code spans
• ⏰ Reset countdown display - Shows when quota resets with local timezone clock time (hours/days + HH:MM)
• 🏷️ Account plan display - Shows your subscription tier (Lite, Pro, etc.)
• ⚡ Fail-fast error handling (no retry logic - user controls when to retry)

Installation

Option 1: npm (Recommended)

# Install plugin
npm install opencode-glm-quota

# Run installer to configure OpenCode
npx opencode-glm-quota install

What the installer does:

• Copies /glm_quota command to ~/.config/opencode/command/glm_quota.md
• Copies skill documentation to ~/.config/opencode/skills/glm-quota/SKILL.md
• Automatically adds plugin to your OpenCode config
• Copies agent to ~/.config/opencode/agents/
• Supports --force flag to overwrite existing files

Uninstall

# Remove OpenCode integration files and config
npx opencode-glm-quota uninstall

# If installed globally
npx opencode-glm-quota uninstall --global

What the uninstaller does:

• Removes /glm_quota command
• Deletes skills/glm-quota/SKILL.md
• Removes plugin entry from OpenCode config
• Removes agent file and legacy config
• Runs npm remove opencode-glm-quota (or --global)

Option 2: From GitHub

npm install github:guyinwonder168/opencode-glm-quota

Option 3: Local Development

# Clone and build
git clone https://github.com/guyinwonder168/opencode-glm-quota.git
cd opencode-glm-quota
npm install
npm run build

# Link for local testing
npm link

# Run the installer for local testing
node bin/install.js

Quick Start

Once installed, simply run the plugin command in OpenCode:

/glm_quota

The plugin will automatically detect your credentials (from OpenCode authentication) and display your usage statistics.

Usage

Authentication Setup

This plugin uses OpenCode's built-in authentication system. No manual configuration required.

Primary Method (Recommended):

# In OpenCode TUI
/connect
# Select: Z.AI Coding Plan or Z.AI
# Enter your API key

Fallback (Development/Testing Only):

# For Global platform (api.z.ai)
export ZAI_API_KEY="your-api-key"

# For CN platform (open.bigmodel.cn)
export ZHIPU_API_KEY="your-api-key"

Running the Plugin

After authentication, simply run:

/glm_quota

Error Handling

The plugin uses fail-fast error handling. If any API request fails, it will display the error and stop (no automatic retries). This gives you full control over when to retry.

Example Error Output:

### ⚠️ Credentials Not Found

Please authenticate first.

**How to fix:**
1. Run `/connect` command in OpenCode TUI.
2. Select "Z.AI Coding Plan", "Z.AI", or "Zhipu".
3. For development/testing, set `ZAI_API_KEY` or `ZHIPU_API_KEY`.

API Reference

This plugin queries three Z.ai monitoring endpoints:

Endpoint	Purpose	Query Params
/api/monitor/usage/quota/limit	Current quota percentages	None
/api/monitor/usage/model-usage	Model usage (24h window)	startTime, endTime
/api/monitor/usage/tool-usage	MCP tool usage (24h window)	startTime, endTime

Platform Detection

The plugin automatically detects the platform based on the provider ID used during authentication:

Provider ID	Platform	API Base URL
zai-coding-plan	ZAI	https://api.z.ai
zai	ZAI	https://api.z.ai
zhipu	ZHIPU	https://open.bigmodel.cn

Credential Priority

The plugin discovers credentials in this order:

1. OpenCode authentication context (managed by OpenCode) - PRIMARY
2. Environment variable ZAI_API_KEY (Global) or ZHIPU_API_KEY (CN) - FALLBACK (dev/testing only)

Where credentials are read: OpenCode stores auth.json at ~/.local/share/opencode/auth.json on all platforms, including Windows. On Windows the plugin additionally checks the legacy %LOCALAPPDATA%\opencode\auth.json location as a fallback, trying the XDG path first so a stale legacy or workaround copy can never override current credentials. Every candidate is probed until one yields a valid key.

Time Window

Usage statistics are queried for a 24-hour rolling window:

• Start: Yesterday at current hour (e.g., 14:00:00)
• End: Today at current hour end (e.g., 14:59:59)

Authentication

Critical: The plugin does NOT use "Bearer" prefix in the Authorization header. The token is passed directly:

Authorization: {token}
Accept-Language: en-US,en
Content-Type: application/json
