## 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 pennypress-full-glossary-c70c2b44
```

Example prompt: Pull the full glossary from PennyPress so I can see every term, its definition, part of speech, and any example sentences the publication includes.

## When to prefer this

Choose this endpoint when you need the complete, authoritative glossary from PennyPress in a single call — including all terms, definitions, slugs, and publication metadata. Prefer this over a per-term lookup when you need to index or display the full vocabulary of the publication at once.

## Known failure modes

- Payment not provided or insufficient — endpoint requires $0.25 USDC via x402 protocol
- Invalid HTTP method used — only GET, HEAD, DELETE are accepted
- Service unavailable or glossary not yet populated — returns empty terms array
- Network timeout if the glossary is large

## How this service works

The complete Penny Press glossary in a single JSON response: every author's definition, as used across the essays. Delivered after one payment instead of per-term.

## Output

A JSON object containing the publication name, price, format, and an array of glossary terms. Each term includes: term name, URL slug, author's definition (gloss), optional example sentence, optional part of speech, and optional list of article references (appears_in).
