## 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 particle-pro-list-podcast-guests-278d0e9a
```

Example prompt: Pull up the full guest roster for the 'How I Built This' podcast — show me the first 25 guests grouped by person.

## When to prefer this

Use this endpoint when you need a comprehensive, paginated list of all past guests for a specific podcast grouped by person — ideal for guest research, booking intelligence, or competitive analysis. Prefer this over the 'plausible future guests' endpoint when you need historical appearance data rather than booking recommendations.

## Known failure modes

- Invalid or non-existent podcast ID/slug returns a 404 error
- Expired or invalid pagination cursor returns an error or unexpected results
- Podcast with no identified guests returns an empty list
- Rate limiting or payment failure (x402) blocks the request
- Malformed query parameters (e.g. non-integer limit) result in a validation error
