Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-analyzed-podcasts-for-publisher-cbc7577b
```

Example prompt: Show me all of NPR's podcasts that have been bias-analyzed, filtered to only LEFT and LEANS_LEFT buckets, sorted by lean score from most to least left-leaning, using the US political framework.

## When to prefer this

Use this endpoint when you need to enumerate and filter a specific publisher's podcast catalog by political bias metrics — especially when you know the publisher slug (e.g. 'npr', 'iheartpodcasts') and need paginated, filterable bias data. Prefer this over a general podcast search when the publisher scope is fixed and bias bucketing or lean score sorting is the primary dimension of interest.

## Known failure modes

- Unknown publisher ID/slug returns 404 or empty result set
- Invalid bias bucket value in filter returns 400 validation error
- Unsupported political_context enum value returns 400
- Expired or invalid pagination cursor returns 400 or resets pagination
- Publisher has no analyzed podcasts, returning empty list with no cursor
- Rate limiting or payment failure returns 402 or 429

## How this service works

List analyzed podcasts for a publisher. Returns a paginated list of the publisher's analyzed podcasts with their latest bias analysis attached.

## Output

A paginated JSON list of the publisher's podcasts, each entry including the podcast name, its latest bias label (e.g. LEFT, CENTER, NOT_POLITICAL), lean score on a -3 to +3 scale, the political context framework used, and the timestamp of the most recent analysis. A pagination cursor is included for fetching subsequent pages.
