## 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 forgemesh-library-harvard-classics-shelf-2ae8e6aa -d '<json body>'

Example prompt: Can you pull up the Harvard Classics shelf and show me the top 30 books available, with links to read them in full?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of the Harvard Classics specifically — 48 well-known public-domain works including Pride and Prejudice, The Scarlet Letter, and Don Quixote — with direct routes to full text. Prefer this over sibling shelves (gothic horror, politics, tragedies, etc.) when the user wants the broad canonical Harvard Classics collection rather than a genre-specific subset. No API key required, making it ideal for quick agent-accessible literary lookups.

## Known failure modes

- Requesting more than 50 books returns only the maximum 50
- Invalid limit type (non-integer) may cause a validation error
- Service unavailability returns a non-200 response with no book data
- Payment of 0.003 USDC not processed correctly via x402 results in 402 Payment Required
