## 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-v1-5-image-to-image-e6137663
```

Example prompt: Take my reference image and transform it into a watercolor painting of a sunset over mountains — use 512x512 pixels and 20 diffusion steps for the best quality.

## When to prefer this

Choose this endpoint when you need Stable Diffusion v1.5 img2img transformation without API keys, want to pay per-call in USDC across Base, Polygon, Arbitrum, World, or Solana, and need a simple base64 image response with controllable resolution and quality steps.

## Known failure modes

- Invalid or missing prompt returns an error or blank image
- num_steps outside 1-20 range rejected by schema validation
- Payment failure on selected chain results in 402 response and no image returned
- Width/height values not supported by the model may be ignored or cause errors
- Network timeouts possible for high step counts

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

## Output

A JSON object containing a single 'image' field with a base64-encoded PNG or JPEG of the transformed image, ready to decode and display or save.
