## 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`):

## When to prefer this

Use this endpoint when you need to rank or compare podcasts within a single publisher's portfolio by advertising intensity. Ideal for media buyers researching which shows in a network carry the most ad load, or for competitive intelligence analysts auditing a publisher's monetization. Prefer this over a general podcast search when you already know the publisher and want ad-volume-sorted results scoped to their catalog.

## Known failure modes

- Unknown or invalid publisher slug/ID returns 404 or empty results
- Malformed cursor parameter causes pagination error
- Missing required path parameter 'id' returns 400 bad request
- Rate limit exceeded or payment failure returns 402 or 429
- Publisher exists but has no tracked advertising data returns empty list
