## 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-search-list-13eab1c2
```

Example prompt: Can you find me the top 10 most popular English-language technology podcasts that don't have ads? Sort them by popularity.

## When to prefer this

Use this endpoint when you need to discover, search, or enumerate podcasts from the Particle Pro catalog — especially when fuzzy name matching, topic filtering, language filtering, or ad-presence filtering is required. Prefer this over generic podcast directories when you need rich metadata like popularity percentiles, match quality signals, and suitability tiers. Use the q parameter for forgiving name-based search and topic_id for category browsing.

## Known failure modes

- Invalid or unknown cursor returns an error or empty results
- Filtering by slug with a non-existent slug returns an empty list
- Sparse episode coverage causes ad-free filter to exclude some legitimate shows
- Very broad queries with no q or topic_id default to popularity ordering which may not be what user expected
- Language code typos or unsupported values may return no results or an error

## How this service works

List and search podcasts. Returns a paginated list of podcasts, with filters for topic, language, suitability tier, popularity, and format.

## Output

A paginated list of podcast objects, each including the podcast name, stable slug, popularity percentile, language, topic tags, suitability tier, ad presence flag, format, match quality (name vs description match), and a cursor for fetching the next page.

The search is forgiving: it handles typos, missing or extra words ('offline jon favreau' finds Offline with Jon Favreau), a name plus qualifiers ('equity techcrunch'), and pasted episode titles ('Ferrari | Acquired' finds Acquired). The best matches come first, and each result's match_quality tells you how confident the match is — including when a show matched only through its description (match_quality=description) rather than its name."
