## 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-attribute-extraction-a846f420 -d '<json body>'
```

Example prompt: Pull the 'id' attribute from the page title element on https://example.com/product-guide that contains the word 'product' and tell me what value it has.

## When to prefer this

Choose this endpoint when you need to extract a specific HTML attribute (such as id, class, data-*, or aria-*) from a page title element on a static webpage or supplied HTML snippet, and you do not need JavaScript execution. It is ideal for lightweight metadata audits, accessibility checks, deduplication workflows using previous_texts, or any task where a known attribute on a title element must be retrieved cheaply and quickly without a full headless browser.

## Known failure modes

- URL is inaccessible, behind a login, or returns a non-200 status — no content to parse
- Page relies on JavaScript rendering so title element is not present in static HTML
- No title element matches the specified search term — empty result returned
- Attribute name pattern fails validation (must match ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$)
- HTML input exceeds 100,000 character limit
- URL exceeds 2,048 character limit
- Attribute requested does not exist on the matched element — null or empty result
