curl https://api.minirouter.sh/v1/chat/completions \
  -H "Authorization: Bearer $MINIROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "minirouter/fusion:cheap",
  "messages": [
    {
      "role": "user",
      "content": "Explain an API gateway in one sentence."
    }
  ],
  "max_tokens": 256
}'
```
