Claude Max API Proxy Setup

Overview

Replace per-token Claude API billing ($15-75/M tokens) with a flat-rate proxy through your Claude Max ($200/mo) or Pro ($20/mo) subscription. The claude-max-api-proxy package exposes your authenticated Claude Code CLI session as an OpenAI-compatible HTTP endpoint on localhost:3456.

How it works: The proxy uses your already-authenticated claude CLI session to forward requests. No API keys are stored or transmitted by the proxy — it relies on your local CLI login. Any OpenAI-compatible client (OpenClaw, LangChain, custom scripts) connects to localhost:3456.

Source code: github.com/atalovesyou/claude-max-api-proxy — review the source before installing.

When to Use

• Agent API costs exceed $20/month and you have a Claude Max or Pro subscription
• You want to run Claude Opus 4.6, Sonnet 4.6, or Haiku 4.5 without per-token charges
• You're configuring OpenClaw, LangChain, or any OpenAI-compatible client to use Claude

Do not use when:

• You don't have a Claude Max or Pro subscription (get one first at claude.ai)
• You need concurrent request throughput >5 (Max plan has rate limits)
• You're on a shared server where others could access port 3456

Security Notes

• The proxy binds to localhost only by default — it is not accessible from other machines
• It uses your authenticated claude CLI session, meaning anyone with access to port 3456 on your machine can make requests against your subscription
• Never expose port 3456 to the public internet — use firewall rules to restrict access
• Review the package source before installing

Setup Process

1. Prerequisites Check

# Verify Node.js 20+
node --version

# Verify Claude Code CLI is installed and authenticated
claude --version
claude --print "test"   # Should return a response without errors

If claude is not authenticated, run claude login and complete the browser flow.

2. Install and Start

# Review the package source first: https://github.com/atalovesyou/claude-max-api-proxy
npm install -g claude-max-api-proxy
claude-max-api   # Starts on localhost:3456 by default

# Verify:
curl http://localhost:3456/health
# => {"status":"ok","provider":"claude-code-cli",...}

3. Configure Your Client

For OpenClaw (~/.openclaw/openclaw.json):

{
  "env": {
    "OPENAI_API_KEY": "not-needed",
    "OPENAI_BASE_URL": "http://localhost:3456/v1"
  },
  "models": {
    "providers": {
      "openai": {
        "baseUrl": "http://localhost:3456/v1",
        "apiKey": "not-needed",
        "models": [
          { "id": "claude-opus-4", "name": "Claude Opus 4.6 (Max)", "contextWindow": 200000, "maxTokens": 16384 },
          { "id": "claude-sonnet-4", "name": "Claude Sonnet 4.6 (Max)", "contextWindow": 200000, "maxTokens": 16384 },
          { "id": "claude-haiku-4", "name": "Claude Haiku 4.5 (Max)", "contextWindow": 200000, "maxTokens": 8192 }
        ]
      }
    }
  }
}

For any OpenAI-compatible client:

• Base URL: http://localhost:3456/v1
• API key: any non-empty string (proxy ignores it)
• Model IDs: claude-opus-4, claude-sonnet-4, claude-haiku-4

4. Run as Persistent Service (Optional)

# Create systemd user service
# Adjust paths below to match your system — find yours with:
#   which claude-max-api
#   echo $HOME
mkdir -p ~/.config/systemd/user
cat > ~/.config/systemd/user/claude-max-api-proxy.service << EOF
[Unit]
Description=Claude Max API Proxy
After=network.target

[Service]
Type=simple
ExecStart=$(which claude-max-api)
Environment=HOME=$HOME
Environment=PATH=$HOME/.npm-global/bin:/usr/local/bin:/usr/bin:/bin
Restart=on-failure
RestartSec=5

[Install]
WantedBy=default.target
EOF

systemctl --user daemon-reload
systemctl --user enable claude-max-api-proxy
systemctl --user start claude-max-api-proxy

5. Verify

curl http://localhost:3456/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"model":"claude-opus-4","messages":[{"role":"user","content":"Say: proxy working"}]}'
