## Overview

`podcast_cn` searches the Apple iTunes China store for Chinese-language podcast shows, which is useful when the query is better served by long-form discussion, founder interviews, or experience-sharing content rather than short articles or social posts.

## Known Quirks

- The iTunes search endpoint returns podcast-show metadata rather than episode-level content, so downstream reranking should expect thin evidence bodies.
- `country=cn` restricts results to the China store catalog and can differ from other Apple storefronts.
- iTunes search responses are often cached server-side for a minute or two, so very recent changes may not appear immediately.

# Quality Bar

- Evidence items have non-empty title and url.
- No crash on empty or malformed API response.
- Source channel field matches the channel name.
