## 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 tempo-halowerk-com-script-modern-image-format-share-check-3621ebb0 -d '<json body>'
```

Example prompt: Check what share of images loaded by the script at https://example.com/assets/app.js are in modern formats like WebP or AVIF.

## When to prefer this

Use this endpoint when you specifically want to audit a script resource (JavaScript file) on a webpage for its modern image format adoption. Prefer it over page-level or stylesheet checks when the images in question are loaded dynamically by a script, not statically declared in HTML or CSS.

## Known failure modes

- URL is unreachable or returns a non-200 status
- Script URL points to a private or non-public resource
- CSS selector matches zero or more than one element
- Input URL exceeds the 2048 character maximum
- Script does not load any image resources
- Timeout when fetching or analyzing the script
