## 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 stable-diffusion-inpainting-image-edit-bc1c0dc6
```

Example prompt: Take this photo (https://example.com/photo.jpg) and repaint just the masked region (https://example.com/mask.jpg) — replace what's there with a bouquet of red roses, 20 diffusion steps, guidance 7.5.

## When to prefer this

Choose this endpoint when you need to surgically edit a specific region of an existing image rather than generate a new one from scratch. It is ideal when the source image must be preserved outside the edit area. Prefer this over full image generation when only a portion needs changing. Useful when you have a binary mask already prepared (white = repaint, black = keep). The pay-per-use model with no account or API key makes it suitable for low-volume or one-off agent tasks.

## Known failure modes

- Image or mask URL not publicly accessible or not HTTPS — returns error
- Image or mask exceeds 10 MB limit — rejected
- Prompt missing (required field) — validation error
- Invalid base64 encoding for image or mask — decode error
- Seed/steps/guidance out of valid range — parameter error
- Payment not processed — edit not delivered and not charged
- Hosted URL expires after 24 hours — image no longer accessible

## How this service works

Edits an image you provide instead of generating one from scratch: pass the image and a black-and-white mask, and Stable Diffusion inpainting repaints only the white area following your prompt. Image and mask go as https URLs or as base64, up to 10 MB each. Returns a hosted image URL valid for 24 hours. You are only charged if the edit is delivered. No API key, no account.

## Output

A JSON response containing a hosted HTTPS URL pointing to the inpainted image, valid for 24 hours. The image has the original content preserved outside the masked region, with only the white-masked area repainted according to the prompt.
