## 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-episodes-41cd1262
```

Example prompt: Can you pull up the last 20 episodes of the All-In podcast published after January 1, 2024, and filter for any titles mentioning 'AI'?

## When to prefer this

Use this endpoint when you need to enumerate or browse episodes of a known podcast by its slug or ID, optionally filtered by title keyword or publication date. Prefer this over a full-text search endpoint when you know the specific show and want a structured episode list rather than content-level search results.

## Known failure modes

- Invalid or unknown podcast slug/ID returns a 404 or empty result set
- Malformed ISO 8601 date strings in published_after or published_before cause a 400 error
- Expired or invalid pagination cursor returns an error or unexpected results
- Exceeding rate limits or insufficient USDC balance causes a 402 payment required error
- Empty result set when no episodes match the title filter or date range

## How this service works

List episodes for a podcast. Returns a paginated list of episodes for a specific podcast, identified by slug (e.g., 'all-in') or ID.

## Output

A paginated list of podcast episodes for the specified show, each with metadata such as title and publication date, along with an opaque cursor for fetching the next page of results.
