## 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 image-resize-api-klymax402-4366d729
```

Example prompt: Can you resize this image to 800 pixels wide in webp format? Here's the URL: https://example.com/photo.jpg

## When to prefer this

Choose this endpoint when you need to resize or reformat a remote image accessible by URL without downloading and re-uploading it yourself; ideal for lightweight, on-the-fly image resizing tasks where aspect-ratio-preserving single-dimension scaling or format conversion is needed.

## Known failure modes

- Invalid or unreachable image URL returns an error
- Unsupported format string returns a bad request error
- Non-numeric width or height values cause a validation error
- Image too large to process may cause a timeout
- Payment not received results in 402 Payment Required response

## How this service works
