## 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 rotary-agency-books-api-72d0bc63
```

Example prompt: Can you look up book information for 'The Great Gatsby' — I need the author, publication year, and any available metadata about it?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call book metadata lookups without committing to a subscription service. Best suited for agents that need occasional book data enrichment at $0.002/call rather than high-volume or real-time inventory APIs. Avoid if you need authoritative library-grade data with guaranteed schema stability.

## Known failure modes

- Book not found in data source returns empty or null result
- Malformed query parameters may return an error response
- Payment failure (402) if USDC micropayment not completed
- Rate limiting or timeout if upstream data source is unavailable
- Ambiguous title/author may return unexpected results
