Pi coding agent DeepSeek Balance Extension

A Pi coding agent extension that monitors your DeepSeek API account balance and automatically displays it in the footer when using a DeepSeek provider.

Features

• Auto Footer Display: Shows remaining account balance when using DeepSeek models
• Multi-Currency: Prefers USD, falls back to CNY or other currencies from your account
• Smart Caching: Caches balance data for 30 seconds to avoid excessive API calls

Install

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

or

pi install git:github.com/shaftoe/pi-deepseek-usage

or test from source:

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

bun install
bun run build
pi -e .

Usage

Automatic Footer Display

When using a DeepSeek model (e.g., deepseek-v4-flash, deepseek-v4-pro), the extension automatically displays your remaining account balance in the footer:

DeepSeek: $17.35

The footer updates after each AI turn and on model selection changes. When you switch away from a DeepSeek model, the footer is cleared.

Configuration

No configuration needed. The extension automatically:

• Uses cached data for 30 seconds to avoid excessive API calls
• Shows/updates status only when DeepSeek models are active
• Clears status when switching to non-DeepSeek models
• Prefers USD balance, falls back to the first available currency

Make sure your DeepSeek API key is configured (e.g., via DEEPSEEK_API_KEY environment variable or Pi's provider settings).

API

The extension uses the DeepSeek balance endpoint: GET https://api.deepseek.com/user/balance
