## 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 pagebrief-url-summarizer-d7d37ce8
```

Example prompt: Can you give me a structured brief of this article — title, up to 3 summary bullets, and the key facts: https://www.wired.com/story/openai-gpt4-launch/

## When to prefer this

Choose PageBrief when you need a fast, low-cost ($0.01) structured digest of a single public URL — especially when you want a consistent schema (title + bullets + key facts + links) rather than raw HTML or markdown. Ideal for agent workflows that need to quickly triage or summarize web content without building a custom scraper. Prefer this over general LLM-based summarization when you want a structured, schema-consistent output and pay-per-use pricing with no monthly commitment.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error or empty content
- Page has no extractable text (e.g. purely JavaScript-rendered SPA) — may return empty bullets or facts
- Invalid URL format — returns validation error
- URL returns non-200 HTTP status — brief may fail or return partial data
- Rate limiting or network timeout on the target URL — call may fail or return incomplete results

## How this service works
