## 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 nova-structured-data-extractor-e1f3dd6c -d '<json body>'
```

Example prompt: Can you grab the structured content from https://example.com/article — I need the page title, headings, links, and main text all in one clean JSON output?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) structured extraction of a single public webpage into clean JSON fields including text, links, headings, title, canonical URL, and description. It is ideal for agents that need to parse webpage content without setting up their own scraping infrastructure. Prefer alternatives if you need JavaScript-rendered content, bulk crawling of entire sites, or screenshot/visual capture of pages.

## Known failure modes

- URL is not publicly accessible or returns a non-200 HTTP status — extraction will fail or return empty fields
- URL points to a login-gated or paywalled page — content will be incomplete or missing
- URL resolves to a non-HTML resource (PDF, image, etc.) — structured fields may be empty or malformed
- Malformed or invalid URL input — request will be rejected
- Page uses heavy JavaScript rendering — server-side extraction may miss dynamically loaded content
