Token Burn Monitor

Zero-dependency Node.js dashboard. Core API + swappable frontend themes.

Architecture

server.js          → Core API (stable, don't modify)
themes/default/    → Default dark dashboard theme
themes/<custom>/   → User/agent-generated themes
API.md             → API contract for theme developers
config.json        → Port, theme, agents, pricing overrides

Quick Start

bash start.sh            # Start (default port 3847)
bash start.sh status     # Check status
bash start.sh restart    # Restart after config change
bash start.sh stop       # Stop

Configuration

Copy config.default.json to config.json:

{
  "port": 3847,
  "theme": "default",
  "agents": {
    "main": { "name": "Karl", "icon": "/assets/karl.png" }
  },
  "modelPricing": {}
}

• theme: Directory name under themes/. Default: "default"
• agents: Display names/icons. Auto-discovered; config only overrides display.
• port: Also settable via PORT env var.
• modelPricing: Override/add model pricing ($/1M tokens).

Set OPENCLAW_AGENTS_DIR to override agent directory (default: /home/node/.openclaw/agents).

Themes

Themes live in themes//. Minimum: one index.html that fetches data from the API.

To create a custom theme:

1. Read API.md for all available endpoints
2. Create themes/my-theme/index.html
3. Set "theme": "my-theme" in config.json
4. Restart

The default theme (themes/default/) is a full reference implementation.

API Overview

All endpoints return JSON. GET-only. Server binds to localhost. Full docs in API.md.

Security

• Server binds to 127.0.0.1 by default (localhost only)
• No shell execution — all data read from filesystem
• No outbound network requests — default theme uses system fonts
• User prompts redacted by default ([redacted]), opt-in via showPrompts: true in config
• HTML responses include CSP: connect-src 'self'; font-src 'self'
• GET-only — all other HTTP methods rejected

Troubleshooting

• No data: Verify OPENCLAW_AGENTS_DIR points to correct agents directory.
• Port conflict: PORT=4000 bash start.sh
• Theme not loading: Check themes//index.html exists.
