## 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-science-periodicals-shelf-924b7a32 -d '<json body>'

Example prompt: Can you pull up the list of public-domain science periodicals from the ForgeMesh library — show me up to 30 results so I can find an old issue of Lippincott's Magazine?

## When to prefer this

Choose this endpoint when you need to discover or browse a curated collection of public-domain science periodicals, especially 19th-century magazines like Lippincott's. It is best for listing and navigating available titles rather than full-text search (use the sibling full-text search endpoint for passage-level queries). No API key is required and cost is minimal at $0.003 USDC per call.

## Known failure modes

- Limit parameter exceeds 50 — API may reject or cap the result
- No results returned if corpus index is unavailable
- Payment failure if x402 USDC transaction is not completed
- Slow or empty response if the underlying library index has not been populated for this shelf
