## 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`):

zero fetch --capability toolsnap-image-upscale-a04f9bb2 -d '<json body>'
```

Example prompt: Can you upscale this image 4x for me? Here's the URL: https://example.com/photo.jpg

## When to prefer this

Choose this endpoint when you need a quick, single-call AI image upscale with either 2x or 4x magnification, especially within a ToolSnap MCP workflow where you want to avoid setting up a separate image-processing account. Ideal for agents already using the ToolSnap MCP connection who need to enhance image resolution as part of a broader pipeline.

## Known failure modes

- Image URL is not publicly accessible or requires authentication
- Image format not supported by the upscaler
- Upstream upscaling service timeout or unavailability
