## 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 forms-term-context-excerpts-4c23a9c4 -d '<json body>'
```

Example prompt: Find where the word 'shipping' appears in context within the checkout form (id='checkout-form') on https://example.com/checkout — pull out the surrounding text snippets from those form elements.

## When to prefer this

Choose this endpoint when you need to find and extract contextual text snippets around a specific term within HTML form elements, using static HTML parsing without JavaScript execution. It is purpose-built for forms (not arbitrary page content) and is cost-efficient at $0.01 per call. Prefer it over general web scrapers when the target content is specifically inside form tags and you need term-in-context excerpts rather than full-page extraction.

## Known failure modes

- URL is unreachable or returns a non-200 status — no content extracted
- Page requires JavaScript rendering — static parser returns empty or incomplete results
- Term not found in any form element — returns empty excerpts
- HTML exceeds 100,000 character limit — request rejected
- Term parameter missing or too short — validation error
- Attribute pattern does not match allowed format — validation error
