## 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 clonecho-ebook-search-f876f2dd -d '<json body>'
```

Example prompt: Can you search for ebooks about 'dune' and show me the authors, genres, prices, and ratings for what comes up?

## When to prefer this

Use this endpoint when an agent needs to search for eBook metadata (author, genre, price, rating) by a keyword or title term. Prefer this over Project Gutenberg search when the user needs commercial ebook metadata including pricing and ratings, not just public-domain books.

## Known failure modes

- Missing required ?term= query parameter returns an error or empty result
- Term with no matching books returns an empty result set
- Payment of $0.02 USDC not provided results in 402 Payment Required
- Malformed or overly long search term may return an error
- Service downtime returns 5xx error

## How this service works

MEDIA: eBooks — author, genre, price, rating (?term=dune, required). Returns JSON.

## Output

A JSON array of eBook records, each containing fields such as title, author, genre, price, and rating — all matching the provided search term.
