## 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 open-library-book-search-71d073bf
```

Example prompt: Search Open Library for 'The Great Gatsby' and give me the title, authors, first publish year, edition count, ISBNs, and cover image for the top results.

## When to prefer this

Use this endpoint when you need quick bibliographic metadata — title, authors, ISBNs, edition count, cover — for books indexed in Open Library. Prefer this over general web search when structured book data (especially ISBNs or edition counts) is required. Best for discovery and reading list building rather than full book content retrieval.

## Known failure modes

- No results found for obscure or misspelled queries
- Missing fields (e.g. no cover or no ISBNs) for lesser-known books in Open Library
- Query too vague returns unrelated books
- Payment failure or 402 response if x402 payment is not handled
- Rate limiting or timeouts from the upstream Open Library API
