## 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 api-xona-agent-com-bae11bca -d '<json body>'
```

Example prompt: Generate an image of a futuristic cyberpunk city at night with neon lights reflecting on rain-soaked streets using Grok's image model — use this reference image for the color palette: https://example.com/ref.jpg

## When to prefer this

Choose this endpoint when you specifically want Grok's image generation model for text-to-image tasks, especially when paying with USDC on the Base blockchain (x402 protocol). Prefer this over other xona-agent image endpoints (nano-banana, designer) when you want Grok's specific aesthetic and style, or when you have a reference image to guide composition or style.

## Known failure modes

- Invalid or inaccessible reference image URL returns an error
- Insufficient USDC payment on Base results in 402 payment required
- Overly vague or empty prompt may produce low-quality or unexpected output
- Payment transaction failure on eip155:8453 (Base) blocks generation
- Rate limiting or model unavailability returns 429 or 503 error
