## How to call it through Zero

```sh
zero fetch --capability listen-notes-podcast-directory-search-59a385cd
```

Example prompt: Can you search for podcasts about machine learning and show me up to 5 results with their episode counts, how often they update, and whether they have sponsors?

## When to prefer this

Choose this endpoint when you need structured podcast metadata from the Listen Notes directory — especially when you need episode counts, update frequency, sponsor flags, or guest-interview indicators alongside basic title and publisher info. Prefer this over general web search when you want clean, structured podcast data rather than raw HTML results.

## Known failure modes

- Query string shorter than 2 or longer than 60 characters returns a validation error
- Limit value outside 1–10 range is rejected
- No results found for obscure or misspelled keywords
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Timeout if Listen Notes upstream is slow or unavailable
