## 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 page-title-structured-extraction-bac2b7b1 -d '<json body>'
```

Example prompt: Extract the page title from https://example.com/product-guide — look for title elements containing the term 'product' and match those with an id attribute value of 'main-title'.

## When to prefer this

Choose this endpoint when you need fast, lightweight extraction of page title elements from a static HTML page or raw HTML snippet without needing JavaScript rendering or authentication bypass. It is ideal for quickly checking page titles, validating title metadata, or extracting structured title content from publicly accessible pages where rendering speed and cost efficiency ($0.01 per call) matter more than full DOM execution.

## Known failure modes

- URL is behind a login or paywall — static parser cannot access protected content
- URL requires JavaScript rendering — dynamic content will not be present in static parse
- HTML exceeds 100,000 character limit — request rejected
- term parameter missing or empty — validation error returned
- attribute name does not match pattern ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ — validation error
- No matching title elements found for the given term/attribute/attribute_value combination — empty result
- URL is unreachable or returns non-200 HTTP status — fetch error
