## 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-titles-empty-value-report-7773cee6 -d '<json body>'
```

Example prompt: Check whether the page title tag is empty on https://example.com/product-guide — I want an empty value report for the title element with id 'main-title'.

## When to prefer this

Choose this endpoint when you need a fast, lightweight static check to determine if a page's title tag is empty or missing — particularly for SEO audits, content QA pipelines, or HTML template validation where JavaScript rendering is not required. It is purpose-built for page title emptiness detection rather than general-purpose HTML scraping or full SEO analysis.

## Known failure modes

- URL is inaccessible or returns a non-200 status — report may be empty or error
- JavaScript-rendered content not captured — static parser only, dynamic titles may not appear
- HTML exceeds 100,000 character limit — request rejected
- Attribute pattern does not match schema regex — validation error returned
- URL exceeds 2,048 character limit — request rejected
