README

Codex OpenAI Proxy

A proxy server that allows CLINE (Claude Code) and other OpenAI-compatible extensions to use ChatGPT Plus tokens from Codex authentication instead of requiring separate OpenAI API keys.

Overview

This proxy bridges the gap between:

Input: Standard OpenAI Chat Completions API format (what CLINE expects)
Output: ChatGPT Responses API format (what ChatGPT backend uses)

Features

✅ OpenAI API Compatibility: Accepts standard OpenAI Chat Completions requests
✅ ChatGPT Plus Integration: Uses your existing ChatGPT Plus tokens
✅ Cloudflare Bypass: Handles ChatGPT's Cloudflare protection with browser-like headers
✅ HTTPS Support: Works with extensions requiring secure connections (via ngrok)
✅ Streaming Responses: Full streaming support for real-time responses
✅ CLINE Compatible: Tested extensively with CLINE VS Code extension
✅ Array Content Support: Handles both string and array message formats from OpenAI SDK
✅ Universal Routing: Bulletproof request routing that bypasses complex warp conflicts

Quick Start

1. Build and Run

git clone https://github.com/Securiteru/codex-openai-proxy.git
cd codex-openai-proxy
cargo build --release
./target/release/codex-openai-proxy --port 8888 --auth-path ~/.codex/auth.json

2. Setup HTTPS Tunnel (Required for CLINE)

Most VS Code extensions require HTTPS:

# Install ngrok and create your own static domain at https://dashboard.ngrok.com/domains
# Replace 'your-static-domain' with your unique domain name
ngrok http 8888 --domain=your-static-domain.ngrok-free.app

**Security Note**: Always use your own unique ngrok domain. Do not share your domain publicly to prevent unauthorized access to your proxy.
