## Start with GPT Image 2 {#quickstart}

The model name is already filled in. Mint a key in the console, put it in an environment variable, and the call below runs as it stands — provided the organization’s wallet holds funds: a call with nothing to pay with answers 402.

### Image generation

```bash title=curl
curl https://api.kumorouter.com/v1/images/generations \
  -H "Authorization: Bearer $KUMO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-image-2",
    "prompt": "A cloud over a quiet city, in ink."
  }'
```

## Prices {#pricing}

The price list in force does not name this model, so there are no rates to show. The catalog says a model exists; the price list says what it costs, and a cost this platform has not published is not a cost.
