## 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-publisher-advertising-profile-526f3dbf
```

Example prompt: Pull up the advertising profile for iHeartPodcasts — I want to see their total ads, unique sponsors, episode reach, host-read vs pre-recorded breakdown, and top sponsors across all their podcasts.

## When to prefer this

Use this endpoint when you need rolled-up advertising analytics across an entire podcast publisher's portfolio rather than episode- or show-level data. It is ideal for media buyers evaluating publisher reach, brand safety researchers assessing sponsorship patterns, or competitive intelligence workflows comparing publisher ad inventories. Prefer this over individual podcast endpoints when the goal is publisher-level aggregation.

## Known failure modes

- Invalid or unknown publisher slug/ID returns 404 not found
- Publisher exists but has no analyzed podcast data returns empty or zero-value metrics
- Malformed path parameter causes 400 bad request
- Payment not included or insufficient causes 402 payment required
- Rate limiting or quota exceeded returns 429 too many requests
