## 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 free-work-by-id-0103ed68
```

Example prompt: Can you pull up all the download links and rights status for Gutenberg book 1342 — I want to know what formats are available and when the links were last verified?

## When to prefer this

Use this endpoint when you already have a specific Gutenberg number, LibriVox ID, or Internet Archive identifier and need the full, verified download link set with rights metadata — rather than running a broader search. It is the right choice after a search step returns an ID, or when a user already knows the exact work they want.

## Known failure modes

- Unknown or invalid ID returns no results or a 404-style error
- Misformatted ID prefix (e.g. missing 'gutenberg:' namespace) may fail to resolve
- Stale or broken download links if the last-verified date is old
- Paid endpoint — insufficient USDC balance causes payment failure before lookup
- Works removed from source catalogues may return empty link sets

## How this service works

One catalogued work by id with every download link and its rights status, last-verified date and source page. Use after a search, or with a known Gutenberg number (gutenberg:1342), LibriVox id (librivox:47) or Internet Archive identifier. $0.01 per lookup.

## Output

A structured record for the requested work including: all available download links with their formats (epub, Kindle, mp3, etc.), the rights/license status of the work, the date the links were last verified, and the URL of the original source page (Gutenberg, LibriVox, or Internet Archive).
