## 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 santos-ai-website-intelligence-summarize-api-ab3d2549
```

Example prompt: Can you summarize the content at https://stripe.com/pricing and pull out the key facts about their pricing tiers?

## When to prefer this

Choose this endpoint when you need a structured, machine-readable summary of any public webpage — especially when you want key facts and named entities extracted alongside the prose summary. Ideal for research workflows, competitive intelligence, or when an agent needs to quickly digest web content without full scraping infrastructure. The optional focus parameter makes it especially useful when you only care about a specific topic (e.g. pricing, security, features) on a given page.

## Known failure modes

- Non-HTML URLs (PDFs, images, JSON files) may not be supported
- Private or paywalled pages will fail or return incomplete content
- Pages with heavy JavaScript rendering may yield incomplete HTML
- HTTP 4xx/5xx from the target URL will be reflected in http_status
- Very long pages may be truncated before summarization
- Rate limiting or payment failure returns 402
