## 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 scrapfly-book-search-api-83b08a71 -d '<json body>'
```

Example prompt: Search for the top 5 books about machine learning and give me a list with authors and titles.

## When to prefer this

Choose this endpoint when you need to search for books by title, author, or topic and receive structured metadata. It is especially useful for agents building reading lists, doing bibliographic research, or powering book recommendation features. Prefer this over general web scraping endpoints when the specific target domain is books and you want pre-structured results rather than raw HTML.

## Known failure modes

- Missing required 'query' field returns a validation error
- Empty or vague query may return no results or low-relevance books
- Network or upstream scraping failure may return success: false
- Rate limiting or payment failure via x402 may block the request
- Requesting a very large 'num' value may time out or return partial results
