## 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 the-phoblographer-content-url-list-e19d67f8
```

Example prompt: Can you pull the full list of available The Phoblographer articles from the Proofivy library, including their slugs and last updated dates?

## When to prefer this

Use this endpoint when you need to discover all available The Phoblographer articles indexed by Proofivy before fetching individual article content. It is the correct starting point for any workflow that enumerates or monitors The Phoblographer content catalog specifically, rather than CryptoSlate or other publishers served by sibling endpoints.

## Known failure modes

- Payment not fulfilled via x402 protocol returns a 402 Payment Required response
- Network timeout if the library server is unavailable
- Empty content_urls array if no Phoblographer content is currently indexed
- Invalid HTTP method (non-GET) returns an error
