## 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 aside-blocks-duplicate-value-report-e43b58bf -d '<json body>'
```

Example prompt: Check the aside blocks on https://example.com/product-guide for duplicate 'id' attribute values — also flag anything that matches previous texts like 'Older example', and search for aside elements related to 'product'.

## When to prefer this

Use this endpoint when you need to audit a static HTML page's aside blocks specifically for duplicate attribute values, such as catching repeated IDs or data attributes in sidebars and callout blocks. It is ideal for pre-deployment HTML validation, content audits, or automated QA pipelines where uniqueness of aside element attributes matters. Prefer this over a generic HTML scraper when the task is specifically about aside elements and duplicate detection rather than general content extraction.

## Known failure modes

- URL is unreachable or returns non-200 status — no HTML to parse
- Page requires JavaScript rendering which is not supported — may return empty or incomplete aside list
- HTML exceeds 100,000 character limit — request rejected
- Invalid attribute name pattern — rejected by schema validation
- No aside elements found on the page — empty report returned
- URL and HTML both empty — nothing to parse
