# Ein AI Proxy - Project Context

Anthropic-compatible proxy that routes AI requests to multiple providers based on model name: sonnet→GLM-4.7 (Z.ai), opus→Anthropic, haiku→DeepSeek.
`.clinerules` is a symlink to this file so Roo Code reads the same context.

## File Structure
- `proxy.mjs` - Main proxy server (zero dependencies, Node.js built-ins only)
- `config.json` - API keys, auth token, and pricing (gitignored)
- `config.example.json` - Template config
- `usage-data.json` - Token usage tracking, auto-generated and gitignored
- `ein-ai-proxy.service` - Systemd unit file
- `deploy.sh` - Deployment and testing script
- `sync-context.sh` - Syncs global context to Claude Code and Roo Code

## Development
Run locally: `node proxy.mjs` (requires `config.json`)
Test health endpoint: `curl http://localhost:3100/health`
Check usage: `curl http://localhost:3100/usage`
Zero npm dependencies — do not add any.

## Deployment
On mini-server (ssh mini-server): `cd ~/ai-proxy && git pull && sudo systemctl restart ein-ai-proxy`
View logs: `sudo journalctl -u ein-ai-proxy -f`
