## 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-literal-term-matches-e046bb81 -d '<json body>'
```

Example prompt: Can you scan the page at https://example-company.com/contact and find all <address> blocks whose text contains the literal word 'headquarters', looking at the 'data-kind' attribute?

## When to prefer this

Choose this endpoint when you need to extract <address> HTML elements from a single static public page or provided HTML snippet by literal keyword match — especially when you want to filter by a specific HTML attribute and deduplicate against previously collected results. Prefer it over general-purpose scrapers when the target is specifically the HTML <address> element type and no JavaScript rendering is required.

## Known failure modes

- URL is inaccessible, behind a login, or requires JavaScript rendering — static parser cannot retrieve content
- HTML input exceeds 100,000 character limit — request rejected
- Term parameter is empty or missing — validation error
- No matching <address> elements found — empty result set returned
- Malformed attribute name pattern — schema validation failure
- URL and HTML both empty — ambiguous or failed parse
