A Pi Coding Agent extension that adds Alibaba Cloud Bailian Coding Plan as a provider. This extension enables Pi to connect to Bailian's Coding Plan subscription service.

Note: This is a provider extension, not the Coding Plan service itself. You must subscribe to Alibaba Cloud's Bailian Coding Plan separately to use this extension.

• 🔌 Connects Pi to Alibaba Cloud's Bailian Coding Plan API
• 🌍 Supports both International and China region endpoints
• 🔐 Handles API key configuration via environment variable or interactive login
• 📋 Provides model definitions for 9 AI models available through Coding Plan

These models are provided by Alibaba Cloud Bailian Coding Plan (subscription required):

You must subscribe to Alibaba Cloud Bailian Coding Plan to use this extension.

1. Subscribe to Coding Plan

   • Visit Alibaba Cloud Model Studio
   • Subscribe to Pro plan ($50/month, provided by Alibaba Cloud)
   • Get your API key (format: sk-sp-xxxxx) from Alibaba Cloud

2. Pi Coding Agent installed

   npm install -g @mariozechner/pi-coding-agent

pi install git:github.com/Dopingus/pi-bailian

pi install /path/to/pi-bailian

pi -e git:github.com/Dopingus/pi-bailian

Use Pi's built-in /login command:

pi
/login bailian-coding-plan

You'll see instructions with the console URL. The browser will NOT open automatically - you need to:

1. Manually open the console URL in your browser
2. Get your API key from the Coding Plan page
3. Paste the API key in the terminal

The key is securely stored in ~/.pi/agent/auth.json.

Available login targets:

• /login bailian-coding-plan - International region
• /login bailian-coding-plan-cn - China mainland region

export BAILIAN_CODING_PLAN_API_KEY=sk-sp-xxxxx
pi

Store in ~/.pi/agent/auth.json:

{
  "bailian-coding-plan": {
    "type": "oauth",
    "refresh": "sk-sp-xxxxx",
    "access": "sk-sp-xxxxx",
    "expires": 1776268800000
  }
}

In Pi interactive mode:

/model

Then select:

• bailian-coding-plan/qwen3.5-plus (recommended)
• bailian-coding-plan/glm-5
• bailian-coding-plan/kimi-k2.5
• bailian-coding-plan/MiniMax-M2.5
• etc.

Or use CLI flag:

pi --provider bailian-coding-plan --model qwen3.5-plus "your prompt"

For users in mainland China, use the China endpoint:

# Interactive login
/login bailian-coding-plan-cn

# Or environment variable
export BAILIAN_CODING_PLAN_API_KEY=sk-sp-xxxxx
pi --provider bailian-coding-plan-cn --model qwen3.5-plus

These quotas are set by Alibaba Cloud Bailian Coding Plan:

Pro Plan ($50/month from Alibaba Cloud):

• 6,000 requests per 5 hours (sliding window)
• 45,000 requests per week (resets Monday 00:00 UTC+8)
• 90,000 requests per month (resets on subscription date)

Check your usage on the Coding Plan Console (Alibaba Cloud's dashboard).

⚠️ API Key Format: Coding Plan API keys start with sk-sp- prefix. Do not use regular Model Studio API keys (sk-).

⚠️ How It Works: This extension configures the correct endpoints automatically:

• International: https://coding-intl.dashscope.aliyuncs.com/apps/anthropic
• China: https://coding.dashscope.aliyuncs.com/apps/anthropic

Pi's anthropic-messages API implementation appends /v1/messages to construct the final URL:

• Final: https://coding-intl.dashscope.aliyuncs.com/apps/anthropic/v1/messages ✅

⚠️ Usage Policy: Coding Plan is for interactive coding tools only. Do not use for:

• Automated scripts
• Custom application backends
• Non-interactive batch API calls

Violation may result in subscription suspension.

Ensure you're using the Coding Plan-specific API key (starts with sk-sp-), not the general Model Studio API key (sk-).

To fix:

1. Run /logout bailian-coding-plan
2. Run /login bailian-coding-plan again
3. Double-check you copied the correct key from the Coding Plan console

1. Check that your subscription is active
2. Verify the model is included in your plan
3. Try qwen3.5-plus (most widely supported)

Use the China region provider:

/login bailian-coding-plan-cn

# View stored credentials
cat ~/.pi/agent/auth.json

# List available OAuth providers
/login
