## 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-podcasts-a-guest-has-appeared-on-2bbbc0f8
```

Example prompt: Which podcasts has Lex Fridman appeared on as a guest? Use his person slug and show me how many times he appeared on each, along with the first and last appearance dates and any brand-safety or bias ratings for those shows.

## When to prefer this

Use this endpoint when you need a comprehensive view of all podcasts a specific person has guested on, especially when appearance frequency, timeline data, and podcast-level brand-safety or bias attributes are important. Prefer this over episode-level endpoints when you want aggregated per-show statistics rather than individual episode details.

## Known failure modes

- Unknown or invalid guest ID returns a 404 not found error
- Malformed pagination cursor returns a 400 bad request error
- Guest with no recorded podcast appearances returns an empty list
- Rate limiting or payment failure returns a 402 or 429 error
- Invalid limit parameter returns a validation error

## How this service works

List podcasts a guest has appeared on. Returns the distinct set of podcasts a guest has appeared on, with per-podcast appearance counts, first/last appearance dates, and the podcast's brand-safety and bias attributes when evaluated.

## Output

A paginated list of distinct podcasts the specified guest has appeared on, each entry including the podcast name/ID, total appearance count on that show, first and last appearance dates, and evaluated brand-safety and political bias attributes for the podcast. Also includes a pagination cursor for retrieving subsequent pages.
