## 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 address-blocks-text-length-statistics-b9b8ea8b -d '<json body>'
```

Example prompt: Can you get the text length statistics for all address blocks on this page https://example.com/contact — specifically the ones where the id attribute is 'main-address', and compare against previous text 'Old Address Block'?

## When to prefer this

Use this endpoint when you need to measure or audit the text length of HTML address block elements on a static webpage or known HTML fragment, particularly when filtering by a specific HTML attribute. Prefer this over generic scraping tools when you need structured text length statistics specifically scoped to address elements rather than full page text extraction.

## Known failure modes

- URL is inaccessible or returns non-200 status — parsing fails with no content returned
- JavaScript-rendered content will not be captured since only static HTML parsing is performed
- No matching address elements found for the specified attribute/attribute_value combination — empty result
- HTML exceeds 100,000 character limit — request rejected
- Malformed attribute pattern not matching regex ^[a-zA-Z][a-zA-Z0-9:_-]{0,49}$ — validation error
- URL exceeds 2048 character limit — rejected
