## 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 web-page-brief-evidence-7b5bdb43
```

Example prompt: Can you fetch https://www.bbc.com/news/science-56837908 and give me a structured brief with the key claims, named entities, sentiment, and the exact quotes that back each claim?

## When to prefer this

Choose this endpoint when you need not just a summary but evidence-backed, source-quoted claims extracted from a single public web page. It is ideal for fact-checking, research briefs, competitive intelligence, and content analysis workflows where traceability of claims to their exact source text is required. Prefer the deep variant (web-page-brief-deep) when multi-page crawling or a larger model is needed.

## Known failure modes

- URL is behind a paywall or login — content cannot be fetched, returns error
- URL is invalid or unreachable — returns fetch failure
- Page contains only images or JavaScript-rendered content with no accessible text — summary may be empty or incomplete
- Rate limiting or timeout from the target server — returns timeout error
- Unsupported content type (e.g. PDF without text layer) — may return partial or empty results

## How this service works

Turn a web page URL into a structured, evidence-backed brief: clean content summary, key points, named entities, sentiment, and claims each quoted with its evidence and source URL. Convierte una URL en un informe estructurado con evidencia: resumen del contenido, puntos clave, entidades, sentimiento y afirmaciones, cada una con su cita textual y su URL de origen.

## Output

A structured JSON object containing: a clean content summary of the page, a list of key points, named entities (people, organizations, locations), overall sentiment, and a list of claims each paired with the exact quoted text from the source page and the source URL.
