## 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`):

Example prompt: Can you rank the definition list items on https://example.com/glossary by text length, looking for entries with the id attribute set to 'main-glossary' that contain the term 'product'?

## When to prefer this

Choose this endpoint when you need to specifically rank HTML definition list (<dl>) elements by text length from a static webpage or raw HTML, especially when filtering by a specific attribute and search term. It is ideal for content audits, glossary analysis, documentation quality checks, or comparing description lengths across a set of definitions. Prefer this over general text extraction tools when your target content is specifically in <dl> format and you need length-based ranking rather than raw extraction.

## Known failure modes

- URL is unreachable or returns non-200 status
- Page requires JavaScript rendering (static parsing only, no JS execution)
- No matching definition list found for the given attribute/attribute_value combination
- Term not found in any definition list on the page
- HTML input exceeds 100,000 character limit
- Attribute name does not match pattern requirements
- Login-protected or paywalled pages cannot be accessed
