## 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 x402-gateway-production-up-railway-app-ca5124a6 -d '<json body>'
```

Example prompt: Generate a photorealistic image of a misty Japanese mountain temple at sunrise in a 16:9 widescreen aspect ratio using Google Imagen — also search the web to make the scene more accurate.

## When to prefer this

Choose this endpoint when you need high-quality image generation with precise aspect ratio control backed by Google's Imagen Nano model. Prefer this over FLUX Schnell when quality matters more than speed, and over generic generation endpoints when you want optional web search grounding to improve prompt accuracy.

## Known failure modes

- Invalid or missing prompt returns 400 error
- Unsupported aspect ratio value returns validation error
- Web search augmentation fails silently or returns stale results
- Payment not fulfilled returns 402 Payment Required
- Model content policy violation causes generation refusal
- Timeout on complex or high-resolution prompts
