## 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-com-book-metadata-title-3feb736f
```

Example prompt: Can you pull up the metadata for the book 'The Pragmatic Programmer' — I need author, publisher, and any other details you can find?

## When to prefer this

Choose this endpoint when you have a specific book title and need structured bibliographic metadata without needing to perform a broader search. It is best for direct title-to-metadata lookups rather than fuzzy or keyword-based searches — use the sibling book-metadata-search endpoint for discovery scenarios.

## Known failure modes

- Book title not found returns empty result or 404
- Ambiguous titles may return metadata for the wrong edition or a different book with a similar name
- URL-encoded special characters in titles may cause parsing errors
- Rate limiting or payment failures result in 402 or 429 errors
