## 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 unordered-lists-word-frequency-analyzer-c9f80542 -d '<json body>'
```

Example prompt: How often does the word 'organic' appear in the unordered lists on https://example-grocery.com/products — specifically in the list with id 'featured'?

## When to prefer this

Choose this endpoint when you need fast, lightweight word frequency analysis specifically scoped to HTML unordered list elements on a static webpage or supplied HTML snippet. It is ideal for SEO audits, content auditing, nav menu analysis, or product list keyword density checks where JavaScript rendering is not required. Prefer it over full-page text analysis tools when you only care about list-element content, and over general web scrapers when you need the structured frequency count output directly.

## Known failure modes

- URL is not publicly accessible (returns error or empty result)
- Page requires JavaScript rendering (static parser cannot execute JS, returns empty or partial lists)
- Specified attribute or attribute_value does not match any UL element (returns zero frequency)
- HTML input exceeds 100,000 character limit (request rejected)
- URL exceeds 2,048 character limit (request rejected)
- Term is empty or missing (validation error)
- Page behind login or paywall (content not accessible)
