## 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-essays-3fd5bc59
```

Example prompt: Fetch all the full essays from PennyPress for me — I want the complete Markdown text, titles, and word counts for each one.

## When to prefer this

Choose this endpoint when you need the full text of all essays from the PennyPress publication and are willing to pay $0.15 USDC via x402 micropayment. Prefer it over preview or listing endpoints when complete Markdown content is required for reading, summarization, or archiving purposes.

## Known failure modes

- Payment not completed — 402 response returned, content withheld until x402 payment of $0.15 USDC is made
- No essays available — empty array returned if publication has no content
- Network timeout — slow response if server is under load
- Malformed response — missing required fields like slug, title, or content if server has data issues

## How this service works

A repository of essays on freedom, truth, and the structures around us, in machine-readable form. Free for humans. Pennies for machines.

## Output

An array of essay objects, each containing a slug, title, full Markdown content, word count, description, type, format, and price — plus a top-level publication name, format, and price field. Content is the complete essay text delivered after the micropayment is processed.
