## 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`):

zero fetch --capability page-titles-text-length-statistics-fcdbf346 -d '<json body>'
```

Example prompt: Can you pull the page title from https://example.com/product-guide and give me text length statistics for it — I want to know the character count and how it compares to my previous title 'Older product overview'?

## When to prefer this

Choose this endpoint when you need lightweight, static extraction and character-length measurement of HTML page title elements without JavaScript rendering overhead. It is ideal for SEO auditing, content QA pipelines, and comparing title lengths across document versions. Prefer it over full-page scrapers when you only need title text metrics and want a low-cost ($0.01), fast, deterministic result.

## Known failure modes

- URL is inaccessible or returns non-200 status — no title extracted
- HTML contains no matching title element for the given attribute/attribute_value — empty result
- URL requires JavaScript rendering — static parser cannot execute JS, returns incomplete or missing title
- HTML exceeds 100,000 character limit — request rejected
- Invalid attribute pattern — request validation error
- URL exceeds 2048 characters — request rejected
