Pi coding agent Z.ai Usage Extension

A Pi coding agent extension that monitors Z.ai subscription API token usage quota and automatically displays usage in the footer when using the Z.ai provider.

Features

• Auto Footer Display: Automatically shows usage in the footer when using Z.ai models
• Smart Caching: Caches usage data for 30 seconds to avoid excessive API calls
• Time Tracking: Displays remaining time until quota reset

Setup

Prerequisites

• Bun - Fast JavaScript package manager and runtime

Installation

pi install npm:@alexanderfortin/pi-zai-usage

or

pi install https://github.com/shaftoe/pi-zai-usage

or if you prefer to build and keep it checked out locally:

git clone https://github.com/shaftoe/pi-zai-usage
cd pi-zai-usage

# Install dependencies
bun install

# Build the extension
bun run build

# Install the extension
pi install ./

Development

This project uses modern TypeScript development tooling:

• Bun - Fast package manager and runtime
• TypeScript 6 - Static type checking with strict mode enabled
• Biome - Ultra-fast linter and formatter

# Type check
bun run typecheck

# Lint code
bun run lint

# Auto-fix lint issues
bun run lint:fix

# Format code
bun run format

# Run all checks
bun run check

# Watch mode for development
bun run dev

Usage

Automatic Footer Display

When using a Z.ai model (e.g., glm-4.7, glm-5, glm-5-flash), the extension automatically displays the usage in the footer (between brackets the time left for the quota to be reset):

Z.ai: 45% (2h 15m 30s)

The footer updates after each AI turn and on model selection changes.

Configuration

No configuration needed. The extension automatically:

• Uses cached data for 30 seconds to avoid excessive API calls
• Shows/updates status only when Z.ai models are active
• Clears status when switching to non-Z.ai models

API

The extension uses the Z.ai API endpoint: https://api.z.ai/api/monitor/usage/quota/limit

Make sure you're logged in to Z.ai via Pi (/login for Z.ai).

Releasing

This project uses automated publishing to NPM via GitHub Actions. The workflow will:

• Run all CI checks
• Build the package
• Publish to NPM with provenance (signed) via trusted publishing
