## 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 cravvol-url-summarizer-8af6e10f -d '<json body>'
```

Example prompt: Can you summarize the content of https://www.bbc.com/news/technology-68123456 in no more than 150 words?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use web page summary without any API key setup or subscription. Ideal for agents that occasionally need to digest external URLs without committing to a scraping platform contract. Best for single-URL summarization tasks where brevity and low friction matter more than deep structured extraction.

## Known failure modes

- URL is unreachable or returns a non-200 status — summarization fails, success: false
- URL points to non-textual content (PDF, image, video) — may return empty or malformed summary
- maxLength too restrictive — summary may be truncated or incomplete
- Payment via x402 fails or insufficient USDC balance — request not processed
- Rate limiting or Vercel timeout if the target page is slow to load
