## 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 list-items-literal-attribute-matches-fbc0f262 -d '<json body>'
```

Example prompt: From the page at https://example-store.com/products, find all list items where the 'data-kind' attribute exactly equals 'featured' and that contain the word 'shoes'.

## When to prefer this

Choose this endpoint when you need to extract list items from a static, publicly accessible webpage or known HTML blob by matching a specific HTML attribute to an exact literal value. It is ideal for structured scraping tasks where you know the attribute name and value in advance (e.g. id='sidebar', data-type='product') and want only items containing a specific term. Prefer this over generic scrapers when you need deterministic, literal attribute filtering rather than CSS selectors, XPath, or fuzzy matching.

## Known failure modes

- URL is behind a login or paywall — only public static pages are supported
- JavaScript-rendered content will not be visible since no JS execution occurs
- Attribute name pattern mismatch causes validation error (must start with a letter, alphanumeric after)
- No matching list items found returns an empty result set
- HTML exceeds 100,000 character limit
- URL exceeds 2,048 character limit
- Malformed HTML may produce incomplete or no results
