## 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 x402donghang-landscape-image-generation-acc5e33b -d '<json body>'
```

Example prompt: Generate an AI image of a glowing bitcoin coin resting on dark sea glass with a minimal aesthetic, in 1280x720 widescreen format.

## When to prefer this

Choose this endpoint when you need a low-cost ($0.08 USDC), no-signup AI image generation call paid via crypto (USDC/x402), specifically for landscape or configurable aspect ratios (widescreen, portrait, square), and want a direct hosted image URL in return. Prefer over OpenAI DALL-E or Stability AI when you want micropayment-based, anonymous access with no API key registration.

## Known failure modes

- Invalid or missing prompt returns a 400 error
- Prompt exceeding 2000 characters is rejected
- Unsupported size enum value causes a validation error
- Payment not completed (402 Not Paid) if USDC payment via x402 fails
- Image generation model unavailability returns a 500 or service error
- Generated image URL may expire or become unavailable after some period
