## 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 x402-web-search-search-fetch-extract-css-selector-f660cd71
```

Example prompt: Search for 'best electric SUVs 2025' in the general category, fetch up to 3 result pages, and extract all 'table tr' elements from each page so I can compare specs side by side.

## When to prefer this

Choose this endpoint when you need both search result discovery AND structured data extraction from those pages in a single API call, eliminating the need for a separate fetch/scrape step. It is ideal when the target data is addressable by a CSS selector (tables, headings, links, list items). Prefer it over a plain search endpoint when you need page content, and over a raw fetch endpoint when you don't know the URLs in advance.

## Known failure modes

- CSS selector returns no matches on some pages (empty array for that result)
- Page behind JavaScript wall returns incomplete or empty text
- Query returns fewer than requested results if index coverage is low
- max_chars truncation may cut off content needed from long pages
- Rate limit or payment failure if x402 micropayment is not properly signed
- Pages with bot-blocking return 403 or empty body

## How this service works

Search, fetch and extract in one call: top results with page text and the elements matching a CSS selector.

## Output

Returns a combined response containing: the ranked search result URLs and metadata, the extracted readable text of each fetched page (truncated to max_chars), and the list of DOM elements matching the provided CSS selector found on each page.
