## 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-podcast-guest-recommendations-cefdd878
```

Example prompt: Who should I try to book as guests for the All In podcast? Give me a ranked list of people who've been on related shows but never appeared on All In, and include which shows they've guested on so I know the connection.

## When to prefer this

Use this endpoint when you need a data-driven, pre-ranked pipeline of plausible podcast booking candidates derived from network-level guest data rather than manual research. It is especially valuable when you want to surface guests who are established on similar shows but represent genuine gaps on the target podcast, avoiding repeat bookings. Prefer this over generic people-search or social graph APIs when the specific context is podcast booking discovery grounded in actual guest appearance history.

## Known failure modes

- Unknown podcast ID or slug returns a 404 not found error
- Podcast with insufficient related show data may return an empty recommendations list
- Invalid cursor value returns a pagination error
- Requesting a very high limit may be capped or return fewer results than requested
- Rate limiting or quota exhaustion returns a 402 or 429 error

## How this service works

List guests a podcast could plausibly book. Returns people who have guested on the podcast's related shows but never on this one, ranked by how related those venues are and how established the person is on them — a booking pipeline, not a

## Output

A paginated list of recommended guest profiles ranked by a combination of how related the venues they appeared on are to the target podcast, and how established the person is on those venues. Each entry can optionally include the specific related shows that booked that guest (via include=via), providing the chain of evidence for the recommendation. A pagination cursor is returned for fetching additional results.
