## 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-publishers-208af885
```

Example prompt: Show me the top 10 podcast publishers on Particle Pro sorted by catalog size — I want to see which networks have the biggest podcast libraries.

## When to prefer this

Use this endpoint when you need to discover or enumerate podcast publishers/networks rather than individual podcasts or episodes. It is the right choice for directory-style browsing, finding which publisher owns a given network name, or ranking publishers by catalog breadth. Prefer over episode- or show-level endpoints when the user's goal is publisher-level discovery.

## Known failure modes

- Invalid sort parameter value returns a 400 error
- Invalid or expired pagination cursor returns an error or empty result
- Very broad or empty query with high limit may return large payloads or timeout
- No publishers matching the search query returns an empty list

## How this service works

List podcast publishers. Returns a paginated list of podcast publishers, ordered by catalog size (largest first, the default) or alphabetically by name.

## Output

A paginated JSON list of podcast publisher records ordered by catalog size or name, each containing publisher identity fields (name, slug) and podcast count. Includes an opaque cursor for fetching subsequent pages.
