Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-deployer-x402-deployer-workers-dev-70d860c0 -d '<json body>'
```

Example prompt: Take this product photo (https://example.com/product.jpg) and expand it to a 1920x1080 canvas, placing the original image centered, so the AI fills in the background around it using the Bria Expand model.

## When to prefer this

Choose this endpoint when you need to outpaint or expand an image with a commercially licensed model (Bria Expand), especially when the output will be used in commercial projects. Prefer this over open-source alternatives when commercial licensing is required and you need realistic, high-quality border generation with controllable canvas sizing and placement.

## Known failure modes

- Invalid image URL or unreachable source image returns an error
- Canvas dimensions smaller than original image dimensions cause a validation error
- Unsupported image format results in processing failure
- Placement coordinates that put the original image outside the canvas bounds return an error
- Payment failure via x402 protocol results in 402 response before processing begins

## How this service works

AI image outpainting / image expansion. Bria Expand model. Generates realistic content beyond original borders. Set canvas size + original placement. Commercial-license model.

## Output

Returns an outpainted image with the original content placed at the specified position within a larger canvas, with realistic AI-generated content filling the expanded areas beyond the original borders.
