## 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-term-context-excerpts-56fa105f -d '<json body>'
```

Example prompt: Look at the page https://example.com/product-guide and find all context excerpts around the word 'warranty' inside the textarea with id 'description' — just static HTML parsing, no JavaScript needed.

## When to prefer this

Choose this endpoint when you need to extract focused, term-centric text excerpts from textarea elements on a static HTML page, particularly when you know the textarea's identifying attribute and value. It is ideal for lightweight, low-cost ($0.01) single-page extraction tasks where JavaScript rendering is not required and you want context windows around a specific keyword rather than full textarea dumps.

## Known failure modes

- No textarea found matching the given attribute/value combination — returns empty result
- Term not found in any matched textarea content — returns empty excerpts
- URL is inaccessible or returns non-200 status — request fails
- JavaScript-rendered content is not captured since only static HTML is parsed
- HTML input exceeds 100,000 character limit — rejected
- Term parameter missing or empty — rejected by schema validation
