Connect Claude Code

Overview

Claude Code is Anthropic's AI coding assistant that supports redirecting API calls to any Anthropic-compatible endpoint via ANTHROPIC_BASE_URL. Wuliang Open AI provides an Anthropic-compatible API endpoint that works seamlessly as a backend for Claude Code.

Prerequisites

• Claude Code installed (npm install -g @anthropic-ai/claude-code)
• An API Key created on the Wuliang Open AI platform

Configuration Steps

1. Edit settings.json

Locate and edit the following file for your operating system (create it if it doesn't exist):

OS	File Path
macOS / Linux	~/.claude/settings.json
Windows	%USERPROFILE%\.claude\settings.json

Write the following content, replacing your-api-key with your Wuliang Open AI API Key:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "your-api-key",
    "ANTHROPIC_BASE_URL": "https://open.dieyuyun.com",
    "API_TIMEOUT_MS": "3000000",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": 1
  }
}

Field	Description
ANTHROPIC_AUTH_TOKEN	Your Wuliang Open AI API Key
ANTHROPIC_BASE_URL	Redirects Claude Code to Wuliang's Anthropic-compatible endpoint
API_TIMEOUT_MS	Request timeout in milliseconds (default 3000000 = 50 minutes)
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC	Disables non-essential calls to Anthropic's servers

2. Edit .claude.json

Locate and edit the following file (create it if it doesn't exist):

OS	File Path
macOS / Linux	~/.claude.json
Windows	%USERPROFILE%\.claude.json

Write the following content to skip the Anthropic onboarding flow:

{
  "hasCompletedOnboarding": true
}

3. Restart Your Terminal

After saving both files, open a new terminal window and start Claude Code:

API Endpoint Reference

Wuliang Open AI Anthropic-compatible endpoint details:

Field	Value
Base URL	https://open.dieyuyun.com
Auth Header	x-api-key: your-api-key
Version Header	anthropic-version: 2023-06-01

Example request:

curl --request POST 'https://open.dieyuyun.com/v1/messages' \
  --header 'x-api-key: your-api-key' \
  --header 'anthropic-version: 2023-06-01' \

  --data '{
    "model": "gpt-5.5",
    "max_tokens": 1024,

    "messages": [
      {"role": "user", "content": "Introduce yourself."}
    ]
  }'

Notes

• JSON Validity: Ensure the config files are valid JSON — extra commas or missing brackets will silently break the configuration.
• API Key Security: Never commit your API Key to version control.
• Model Selection: Use the /model command inside a Claude Code session to switch models.
