## When to prefer this

Choose this endpoint when you need real-time trending topic discovery specifically on Bluesky (AT Protocol), especially when you want direct feed URLs to navigate to each trend. Prefer this over scraping Bluesky directly or using Twitter/X trending APIs when your use case is Bluesky-native content discovery.

## Known failure modes

- Bluesky public API unavailable or rate-limited — upstream fetch fails
- limit parameter out of range or non-integer — may return validation error or default count
- No trending topics available at the moment — returns empty topics array
- Network timeout reaching Bluesky AT Protocol endpoints
