## 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 agentutility-app-store-screenshot-expand-37da630f -d '<json body>'
```

Example prompt: Can you expand this App Store screenshot to the full standard iPhone resolution (1290×2796) and give me a link to the processed PNG?

## When to prefer this

Use this endpoint when you need to expand or upscale an App Store screenshot to the standard full iPhone display resolution (1290×2796) and retrieve a hosted PNG URL. Prefer this over generic image upscalers when working specifically with App Store screenshot assets and need the exact standard dimensions.

## Known failure modes

- Invalid or inaccessible screenshot input returns an error
- Unsupported image format fails processing
- Payment failure via x402 results in 402 response before processing begins
- Malformed request body returns validation error
