+# Claude Max API Proxy
+
+**claude-max-api-proxy** is a community tool that exposes your Claude Max/Pro subscription as an OpenAI-compatible API endpoint. This allows you to use your subscription with any tool that supports the OpenAI API format.
+
+## Why Use This?
+
+| Approach | Cost | Best For |
+|----------|------|----------|
+| Anthropic API | Pay per token (~$15/M input, $75/M output for Opus) | Production apps, high volume |
+| Claude Max subscription | $200/month flat | Personal use, development, unlimited usage |
+
+If you have a Claude Max subscription and want to use it with OpenAI-compatible tools, this proxy can save you significant money.
+
+## How It Works
+
+```
+Your App → claude-max-api-proxy → Claude Code CLI → Anthropic (via subscription)
+     (OpenAI format)              (converts format)      (uses your login)
+```
+
+The proxy:
+1. Accepts OpenAI-format requests at `http://localhost:3456/v1/chat/completions`
+2. Converts them to Claude Code CLI commands
+3. Returns responses in OpenAI format (streaming supported)
+
+## Installation
+
+```bash
+# Requires Node.js 20+ and Claude Code CLI
+npm install -g claude-max-api-proxy
+
+# Verify Claude CLI is authenticated
+claude --version
+```
+
+## Usage
+
+### Start the server
+
+```bash
+claude-max-api
+# Server runs at http://localhost:3456
+```
+
+### Test it
+
+```bash
+# Health check
+curl http://localhost:3456/health
+
+# List models
+curl http://localhost:3456/v1/models
+
+# Chat completion
+curl http://localhost:3456/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "claude-opus-4",
+    "messages": [{"role": "user", "content": "Hello!"}]
+  }'
+```
+
+### With Clawdbot
+
+You can point Clawdbot at the proxy as a custom OpenAI-compatible endpoint:
+
+```json5
+{
+  env: {
+    OPENAI_API_KEY: "not-needed",
+    OPENAI_BASE_URL: "http://localhost:3456/v1"
+  },
+  agents: {
+    defaults: {
+      model: { primary: "openai/claude-opus-4" }
+    }
+  }
+}
+```
+
+## Available Models
+
+| Model ID | Maps To |
+|----------|---------|
+| `claude-opus-4` | Claude Opus 4 |
+| `claude-sonnet-4` | Claude Sonnet 4 |
+| `claude-haiku-4` | Claude Haiku 4 |
+
+## Auto-Start on macOS
+
+Create a LaunchAgent to run the proxy automatically:
+
+```bash
+cat > ~/Library/LaunchAgents/com.claude-max-api.plist << 'EOF'
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
