Claude / OpenAI Chat / OpenAI Images / Codex Responses / Gemini API Proxy - CCX

English | 简体中文

CCX is a high-performance AI API proxy and protocol translation gateway for Claude, OpenAI Chat, OpenAI Images, Codex Responses, and Gemini. It provides a unified entrypoint, built-in web administration, channel orchestration, failover, multi-key management, and model routing.

Features

• Integrated backend + frontend architecture with single-port deployment
• Dual-key authentication with PROXY_ACCESS_KEY and optional ADMIN_ACCESS_KEY
• Web admin console for channel management, testing, logs, and monitoring
• Support for Claude Messages, OpenAI Chat Completions, OpenAI Images, Codex Responses, and Gemini APIs
• Smart scheduling with priorities, promotion windows, health checks, failover, and circuit recovery
• Per-channel API key rotation, proxy support, custom headers, model allowlists, and route prefixes
• Responses session tracking for multi-turn workflows
• Embedded frontend assets for simple binary deployment

Supports multiple upstream service types and flexible API key, model mapping, and request parameter configuration.

Traffic Stats

Real-time monitoring of per-channel request traffic, success rate, and latency.

Architecture

CCX exposes one backend entrypoint:

Client -> backend :3000 ->
  |- /                            -> Web UI
  |- /api/*                       -> Admin API
  |- /v1/messages                 -> Claude Messages proxy
  |- /v1/chat/completions         -> OpenAI Chat proxy
  |- /v1/responses                -> Codex Responses proxy
  |- /v1/images/{...}             -> OpenAI Images proxy
  |- /v1/models                   -> Models API
  `- /v1beta/models/*             -> Gemini proxy

Images endpoints currently include:

• POST /v1/images/generations
• POST /v1/images/edits
• POST /v1/images/variations

See ARCHITECTURE.md for the detailed design.

Quick Start

Option 1: Binary

1. Download the latest binary from Releases
2. Create a .env file next to the binary:

PROXY_ACCESS_KEY=your-super-strong-secret-key
PORT=3000
ENABLE_WEB_UI=true

3. Run the binary and open http://localhost:3000

Option 2: Docker

docker run -d \
  --name ccx \
  -p 3000:3000 \
  -e PROXY_ACCESS_KEY=your-super-strong-secret-key \
  -e APP_UI_LANGUAGE=en \
  -v $(pwd)/.config:/app/.config \
  crpi-i19l8zl0ugidq97v.cn-hangzhou.personal.cr.aliyuncs.com/bene/ccx:latest

Option 3: Build From Source

git clone https://github.com/BenedictKing/ccx
cd ccx
cp backend-go/.env.example backend-go/.env
make run

Useful commands:

make dev
make run
make build
make frontend-dev
