## 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 doab-directory-of-open-access-books-search-6c5ae62d
```

Example prompt: Search the Directory of Open Access Books for peer-reviewed books about digital humanities and give me the first 10 results with their titles, authors, abstracts, and links to the DOAB records.

## When to prefer this

Choose this endpoint when you need to discover peer-reviewed, open access academic books from the DOAB index — the authoritative global directory for open access books. Prefer this over general web search when you need structured metadata (handle, abstract, authors, publication date) specifically for scholarly books that are freely and legally available. It is ideal for literature reviews, research assistance, academic citation discovery, or surfacing free educational texts.

## Known failure modes

- Missing required 'query' parameter returns an error
- Very broad queries return thousands of results requiring pagination
- Obscure or misspelled keywords may return zero results
- DOAB index may lag behind newly published books
- Page number beyond total pages returns empty book array

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

Returns a paginated JSON response containing the search query, total number of matching books, current page, whether more results exist, the source URL used, a check timestamp, and an array of book records each with title, authors, published date, last updated date, abstract excerpt, DOAB handle, and full DOAB record URL.
