## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability xona-agent-nano-banana-image-generator-9c7eaf04 -d '<json body>'
```

Example prompt: Generate an image of a glowing cyberpunk cityscape at night with neon reflections on wet streets, in a 16:9 aspect ratio, using the nano-banana model.

## When to prefer this

Choose this endpoint when you need a lightweight, cost-efficient AI image generation call ($0.05 USDC) on Base Mainnet with support for reference-image-guided style, and you specifically want the Nano Banana model's stylized output rather than a general-purpose image model. Prefer this over the Designer or Seedream endpoints when you want quick, small-scale image generation without advanced style blending or a different model architecture.

## Known failure modes

- Invalid or missing prompt returns a 400 error
- Unsupported aspect ratio value causes a bad request error
- Reference image URLs that are inaccessible or invalid may cause generation failure
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required error
- Model overload or timeout may return a 503 or timeout error
