## 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-works-fae3dbc4
```

Example prompt: Can you pull up the full metadata for the book with Open Library work ID OL82563W — I need the title, authors, subjects, and description?

## When to prefer this

Use this endpoint when you have a specific Open Library work ID (OL…W format) and need structured bibliographic metadata about that work. Prefer this over general book search APIs when you already know the identifier and want canonical Open Library data, or when enriching a dataset with standardized bibliographic fields.

## Known failure modes

- Invalid or non-existent work ID returns a 404 or empty result
- Payment failure (x402) if USDC is not properly sent with the request
- Rate limiting if too many requests are made in a short period
- Incomplete data if the Open Library record for that work is sparse
