## 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 engedi-book-lookup-by-open-library-work-id-ad31789f
```

Example prompt: Can you pull up the book details for Open Library Work ID OL45804W — I need the title, author, and any other metadata available?

## When to prefer this

Use this endpoint when you have a specific Open Library Work ID (OLID) and need to retrieve structured book metadata programmatically, especially in agent workflows that already know the OLID. Prefer this over general web search when you need clean, structured book data rather than unstructured HTML, and when you want a pay-per-call model without subscription overhead.

## Known failure modes

- Invalid or malformed OLID returns an error or empty data object
- Book not found in Open Library returns success:false or empty data
- Network timeout from upstream Open Library API
- Payment not received (402 response before data is returned)
- Stale cache data if Open Library record was recently updated
