## 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-html-fragment-extraction-6df09d6d -d '<json body>'
```

Example prompt: Pull out the textarea element with id 'product-description' from https://example.com/product-page and give me its default text content — static page, no JavaScript needed.

## When to prefer this

Use this endpoint when you need to extract the default text content or HTML fragment of textarea elements from a static webpage or known HTML, particularly when you want to filter by a specific HTML attribute (such as id or data-* attributes). It is ideal for auditing pre-filled form fields, diffing textarea defaults over time using previous_texts, or parsing supplied HTML without needing JavaScript rendering or authentication. Prefer this over a general-purpose scraper when your target is specifically textarea elements and you want structured, bounded results with minimal cost.

## Known failure modes

- URL is inaccessible, behind a login, or requires JavaScript rendering — returns no result since only static parsing is performed
- No textarea matching the specified attribute and attribute_value is found in the HTML — returns an empty or null fragment
- HTML payload exceeds the 100,000 character limit — request is rejected
- Attribute name does not match the allowed pattern (must start with a letter, max 50 chars) — validation error
- URL exceeds 2048 characters — validation error
- Page returns a non-200 HTTP status — extraction fails with an access error
