## 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 capi2-web-lookup-21566292 -d '<json body>'
```

Example prompt: Fetch the live page at https://example.com/about and pull out the passages most relevant to 'founding team and company history', up to 200000 bytes.

## When to prefer this

Choose this endpoint when you need to read the live, current content of a specific public URL and want relevance-ranked passages relative to a question or keyword — particularly useful in x402 micropayment agent pipelines where you pay per call. Prefer it over a general web search when you already know the URL and want structured passage extraction rather than a list of search results.

## Known failure modes

- URL is not publicly accessible (returns non-200 status)
- URL points to binary or non-text content (low-quality passage extraction)
- Page requires JavaScript rendering (static fetch may miss dynamic content)
- max_bytes too small to capture meaningful content
- Network timeout or server unreachable on Render infrastructure

## How this service works

Paid x402 utilities and live intelligence for autonomous agents: hashing/encoding plus public web lookup, domain intelligence, API discovery audit, evidence extraction and x402 health.

## Output

Returns a JSON object containing the page title, HTTP status code, content type, and an array of ranked text passages each with its text and relevance score relative to the optional query.
