## 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 articles-structured-extraction-2214e5ea -d '<json body>'
```

Example prompt: Can you extract the article content from https://example.com/news/story and find elements with the attribute 'data-kind' equal to 'body', searching for the term 'article'?

## When to prefer this

Choose this endpoint when you need to extract structured content from a single, publicly accessible article page or known HTML snippet using attribute-based element targeting. It is best suited for static pages that do not require JavaScript rendering or authentication. Prefer this over general-purpose scrapers when you need fine-grained control via attribute name and value matching, and when you want a bounded, cost-predictable single-extraction result at $0.01 USDC per call.

## Known failure modes

- URL is behind authentication or a paywall — endpoint cannot bypass login
- Page requires JavaScript rendering to load content — static parser returns empty or incomplete results
- URL is unreachable or returns a non-200 HTTP status
- HTML input exceeds 100,000 character limit
- No elements match the given attribute/attribute_value/term combination — empty extraction result
- Malformed HTML input causes parsing errors
- attribute parameter does not match the required pattern (must start with a letter, alphanumeric+special chars only)

## How this service works

Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded structured extraction result.

## Output
