## 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 textarea-defaults-distinct-value-extraction-f79ef22d -d '<json body>'
```

Example prompt: Fetch the page at https://example.com/product-form, parse the HTML statically, and extract all distinct default textarea values that contain the word 'product', focusing on textareas where the id attribute equals 'description', while excluding any text we've already seen like 'Older example'.

## When to prefer this

Choose this endpoint when you need to extract and deduplicate default text values from HTML textarea elements on a static (non-JS-rendered) public webpage, especially when you want to filter by a specific HTML attribute and value, search for a keyword within textarea content, and exclude previously captured texts to surface only novel values. Prefer this over general web scrapers when your target is specifically textarea form field defaults rather than general page content.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status
- Page requires JavaScript rendering to display textarea content (not supported — static parsing only)
- No textarea elements match the specified attribute/value filter
- All matching textarea texts are duplicates of previous_texts, returning empty result
- HTML input exceeds 100,000 character limit
- Attribute name fails regex pattern validation
- Term not found in any textarea defaults on the page
