## 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 cravvoul-url-summarizer-d8012ef1 -d '<json body>'
```

Example prompt: Can you summarize the content at https://example.com/article-about-ai for me, keeping the summary under 300 words?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-use web page summary without managing API keys or subscriptions. It is ideal for one-off summarization tasks where the agent needs to quickly digest a URL's content and relay it to the user. Prefer it over heavier scraping pipelines when only a text summary is needed, not raw HTML or structured data extraction.

## Known failure modes

- URL is unreachable or returns a non-200 status — success: false, no summary data
- URL points to a non-text resource (PDF, image, video) — may return empty or malformed summary
- maxLength too small to produce a meaningful summary — truncated or error response
- Payment not processed via x402 — request rejected before processing
- URL is paywalled or requires authentication — content may be incomplete or inaccessible
