## 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 gedx402-stable-diffusion-img2img-x402-42e932e2
```

Example prompt: Take this image and transform it into a cyberpunk cityscape at night — use the prompt 'neon-lit cyberpunk city, rain-soaked streets, futuristic buildings', output at 512x512 pixels with 20 diffusion steps.

## When to prefer this

Choose this endpoint when you need image-to-image transformation via Stable Diffusion v1.5 without managing API keys or subscriptions, and you can pay per-call in USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents with crypto wallet access that need on-demand generative AI image transformation at a fixed low cost per call.

## Known failure modes

- Payment not received or USDC transaction failed — returns HTTP 402 Payment Required
- Prompt missing or empty — may return an error or blank image
- num_steps out of range (must be 1–20) — validation error
- Unsupported width/height values for the model — may be ignored or cause an error
- Network timeout on the Cloudflare Worker — generic 5xx error
