# ForgeMesh Library PS Shelf

> ForgeMesh Library PS Shelf is a paid API for AI agents from library.forgemesh.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Returns a ranked list of up to 50 public-domain books from the PS (American literature) shelf, with drill-down routes for full-text retrieval

## 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-ps-shelf-6a7db690 -d '<json body>'
```

Example prompt: Show me up to 30 classic American literature books from the public-domain PS shelf — things like Moby Dick or Little Women — so I can pick one to read.

## When to prefer this

Use this endpoint when you need a curated, ranked list of public-domain American literature (PS classification) titles, especially when you want to browse or discover books in that category without a specific search query. Prefer this over the full-text search endpoint when you want to enumerate books by shelf rather than search by keyword or passage. No API key is required — only a small per-call USDC micropayment.

## Known failure modes

- Limit exceeds maximum of 50 — clamp to 50 or return error
- Payment not processed — x402 payment required before response is served
- No books returned if shelf index is temporarily unavailable
- Drill-down routes may be unreachable if downstream full-text endpoints are down

## How this service works

Curated shelf: PS — 11828 public-domain books including Moby Dick; Or, The Whale, The Blue Castle: a novel, Little Women; Or, Meg, Jo, Beth, and Amy. Returns a ranked list with drill-down routes for full-text retrieval. No license, no API key required.

## Output

A ranked list of public-domain books from the PS (American literature) Library of Congress classification, including titles like Moby Dick and Little Women, with drill-down routes that allow the agent to retrieve the full text of each book. Returns up to 50 results depending on the limit parameter.
