# Synu & Synthetic API

## The Shell Context

**Laptop (Casey):** zsh — synu as zsh plugin
**Fedora .19 VM (Ani):** fish — synu as fish function

I invoke explicitly: `fish -c 'synu ...'` on .19 VM

## Quick Check

```bash
curl https://api.synthetic.new/openai/v1/models \
  -H "Authorization: Bearer ${SYNTHETIC_API_KEY}"
```

## Synu Usage

```bash
# Show quota (green/yellow/red bars)
synu

# Run agent with prompt
synu <agent> -p "prompt here"

# Interactive mode with flag selection
synu i <agent>
```
