## 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 exchangerebel-book-metadata-search-067d0e9f
```

Example prompt: Can you search for book metadata on 'The Name of the Wind' and give me the author, publisher, ISBN, and a description?

## When to prefer this

Choose this endpoint when you need to look up or enrich book metadata by title, author, or keyword — especially useful for cataloging, reading apps, or bibliographic research. Prefer it over general web search when you need structured, machine-readable book data rather than raw HTML or unstructured text.

## Known failure modes

- No results found for obscure or misspelled titles — returns empty result set
- Ambiguous queries may return irrelevant books if terms are too generic
- Missing metadata fields for older or less-documented books
- Rate limiting or payment failure if x402 payment is not properly handled
- Malformed query parameters may result in 400 Bad Request
