Initial commit: ein-ai-proxy

Anthropic-compatible API proxy that routes requests to multiple providers (Anthropic, Z.ai/GLM-4.7, DeepSeek V3.2) based on model name. Zero dependencies, SSE streaming, bearer token auth. Designed to run behind Caddy/nginx on a home server, enabling Claude Code and Roo Code clients to connect from anywhere.

+# ein-ai-proxy
+
+Anthropic-compatible API proxy that routes requests to multiple AI providers based on model name. Built to run on a home server behind nginx, letting you use Claude Code and Roo Code from any machine while keeping costs optimized.
+
+## How it works
+
+Clients (Claude Code CLI, Roo Code, Cline, etc.) send standard Anthropic Messages API requests to your proxy. The proxy inspects the `model` field and forwards the request to the appropriate provider:
+
+| Client requests | Routed to | Why |
+|---|---|---|
+| `claude-opus-4-6` | Anthropic API | Complex tasks that need the best model |
+| `claude-sonnet-4-6` | Z.ai → GLM-4.7 | Daily workhorse, $10/mo flat rate |
+| `claude-haiku-4-5-*` | DeepSeek → V3.2 | Trivial tasks, pennies per token |
+| `glm-4.7` (direct) | Z.ai | Explicit GLM request |
+| `deepseek-chat` (direct) | DeepSeek | Explicit DeepSeek request |
+
+SSE streaming is fully supported — responses are piped through without buffering.
+
+## Setup
+
+```bash
+# 1. Copy and edit config
+cp config.example.json config.json
+nano config.json  # Add your API keys + set authToken
+
+# 2. Deploy (installs systemd service, tests proxy)
+chmod +x deploy.sh
+./deploy.sh
+
+# 3. Follow the nginx + SSL steps printed by deploy.sh
+```
+
+## Client Configuration
+
+### Claude Code CLI
+
+Add to `~/.claude/settings.json`:
+```json
+{
+  "env": {
+    "ANTHROPIC_BASE_URL": "https://ai.maybe.zone",
+    "ANTHROPIC_AUTH_TOKEN": "your-proxy-auth-token",
+    "API_TIMEOUT_MS": "3000000"
+  }
+}
+```
+
+### Roo Code (VS Code)
+
+1. Open Roo Code settings
+2. Set API Provider to **Anthropic**
+3. Enter your proxy auth token as the API Key
+4. Check **Use custom base URL**
+5. Enter `https://ai.maybe.zone`
+
+## Switching models
+
+From Claude Code, the default Sonnet model routes to GLM-4.7. To use Opus for a complex task, use `/model` and select Opus — the proxy will route it to the real Anthropic API.
