CCR (Claude Code Router)

Built entirely with Claude Code - An AI-powered development workflow

A Cloudflare Worker proxy that enables Claude Code to access OpenRouter's diverse model selection. CCR acts as a translation layer between Anthropic's Claude API format and OpenAI-compatible APIs.

This Cloudflare Worker acts as a translation layer between Anthropic's Claude API format and OpenAI-compatible APIs, specifically OpenRouter. It allows Claude Code to access a wide range of models through OpenRouter while maintaining the familiar Claude API interface.

Key Features:

• 🔄 API Translation: Seamlessly converts between Anthropic and OpenAI API formats
• 🌐 OpenRouter Integration: Access to multiple AI models through OpenRouter's unified API
• ⚡ Cloudflare Workers: Fast, globally distributed proxy with minimal latency
• 🎯 Claude Code Compatible: Designed specifically for Claude Code users

Install Claude Code CLI:

npm install -g @anthropic-ai/claude-code

For more details, see: https://docs.anthropic.com/en/docs/claude-code/setup

Sign up at openrouter.ai and get your API key

# Use either ANTHROPIC_API_KEY or ANTHROPIC_AUTH_TOKEN (both work the same way)
ANTHROPIC_BASE_URL="https://ccr.duyet.net" ANTHROPIC_API_KEY="your-openrouter-api-key" claude
ANTHROPIC_BASE_URL="https://ccr.duyet.net" ANTHROPIC_AUTH_TOKEN="your-openrouter-api-key" claude

# Use either ANTHROPIC_API_KEY or ANTHROPIC_AUTH_TOKEN with custom models
ANTHROPIC_BASE_URL="https://ccr.duyet.net" ANTHROPIC_API_KEY="your-openrouter-api-key" ANTHROPIC_MODEL="moonshotai/kimi-k2:free" ANTHROPIC_SMALL_FAST_MODEL="google/gemini-2.5-flash" claude
ANTHROPIC_BASE_URL="https://ccr.duyet.net" ANTHROPIC_AUTH_TOKEN="your-openrouter-api-key" ANTHROPIC_MODEL="moonshotai/kimi-k2:free" ANTHROPIC_SMALL_FAST_MODEL="google/gemini-2.5-flash" claude

For permanent setup, add to your shell profile:

export ANTHROPIC_BASE_URL="https://ccr.duyet.net"
# Use either ANTHROPIC_API_KEY or ANTHROPIC_AUTH_TOKEN (both work the same way)
export ANTHROPIC_API_KEY="your-openrouter-api-key"
# OR
export ANTHROPIC_AUTH_TOKEN="your-openrouter-api-key"

# Optional: Set default models
export ANTHROPIC_MODEL="moonshotai/kimi-k2:free"
export ANTHROPIC_SMALL_FAST_MODEL="google/gemini-2.5-flash"

# Then simply run:
claude

That's it! Claude Code will now use OpenRouter's models through the CCR proxy.

1. Add the environment variables to your shell profile:

   echo 'export ANTHROPIC_BASE_URL="https://ccr.duyet.net"' >> ~/.bashrc
   # Use either ANTHROPIC_API_KEY or ANTHROPIC_AUTH_TOKEN (both work the same way)
   echo 'export ANTHROPIC_API_KEY="your-openrouter-api-key"' >> ~/.bashrc
   # OR
   echo 'export ANTHROPIC_AUTH_TOKEN="your-openrouter-api-key"' >> ~/.bashrc
   source ~/.bashrc

2. Start Claude Code:

   claude

If you want to deploy your own CCR instance:

# Install Wrangler CLI
npm install -g wrangler

# Clone and deploy
git clone https://github.com/duyet/ccr.git
cd ccr
wrangler deploy

Set your OpenRouter API key:

wrangler secret put OPENROUTER_API_KEY
# Enter your OpenRouter API key when prompted

Update wrangler.toml:

[vars]
OPENROUTER_BASE_URL = "https://openrouter.ai/api/v1"

CCR automatically handles model mapping:

1. OpenRouter Model IDs: Models with / (like moonshotai/kimi-k2:free) are passed through directly
2. Claude Short Names: haiku, sonnet, opus are mapped to their OpenRouter equivalents
3. Custom Models: Any model name set via ANTHROPIC_MODEL environment variable is used as-is

Claude Code users can override the default model using the ANTHROPIC_MODEL environment variable.

⚠️ Important: This is a proxy service. Your API key will be used to make requests to OpenRouter. Make sure to:

• Use a secure connection
• Keep your API key private
• Only use trusted CCR instances

For testing and development:

# Start local development server
wrangler dev

# Test locally with Claude Code
export ANTHROPIC_BASE_URL="http://localhost:8787"
export ANTHROPIC_API_KEY="your-openrouter-api-key"
claude

Authentication Error

Error: Invalid API key

• Ensure your OpenRouter API key is set: wrangler secret put OPENROUTER_API_KEY
• Verify the key is valid at OpenRouter

Model Not Found

Error: Model not found

• Check supported models list above
• Verify model is available on OpenRouter
• Use full OpenRouter model ID if needed

Streaming Issues

Error: Connection timeout or malformed events

• Ensure your OpenRouter API key supports streaming
• Check that the model you're using supports streaming responses

Worker Not Responding

• Check deployment status: wrangler deployments list
• View logs: wrangler tail
• Verify your worker domain is correct

1. Check the OpenRouter documentation
2. View worker logs: wrangler tail
3. Create an issue in this repository
4. Visit your worker homepage for built-in documentation

• Authentication: Currently uses hardcoded token (will be fixed)
• Error Handling: Basic error responses
• Rate Limiting: Not implemented

• OpenRouter - Get your API key
• Cloudflare Workers - Hosting platform
• Anthropic - Claude models
• Wrangler CLI - Deployment tool
