## 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-list-publisher-podcasts-with-suitability-verdicts-61fc396f
```

Example prompt: Pull up the brand safety verdicts for all podcasts from publisher 'wondery', sorted by highest risk first, and flag any that are UNSAFE or have non-NONE exposure in the hate_speech_aggression category.

## When to prefer this

Use this endpoint when you need to audit or filter a specific publisher's entire podcast catalog for brand safety — especially when you require IAB/GARM-tier labels, GARM category-level exposure details, treatment type, and prevalence thresholds. Prefer this over a general podcast search when the publisher is already known and you want a structured safety verdict per show rather than keyword-based discovery.

## Known failure modes

- Invalid or unknown publisher ID returns 404 not found
- Invalid tier or category enum value returns 400 bad request
- Expired or invalid pagination cursor returns 400 or empty result
- No podcasts yet analyzed for the publisher returns empty list
- treatment or min_prevalence filters ignored if category is not also specified
- Rate limiting or payment failure returns 402 payment required

## How this service works

List a publisher's podcasts with their suitability verdicts. Returns a paginated list of the publisher's analyzed podcasts decorated with their latest IAB/GARM tier, confidence, evaluated-at timestamp, and any non-NONE category exposures (flagged

## Output

A paginated list of podcast records, each including the podcast name and ID, its latest IAB/GARM suitability tier (e.g. SAFE, SENSITIVE, UNSAFE), a confidence score, the timestamp of the most recent evaluation, and any GARM category exposures with treatment type and prevalence level. A pagination cursor is included for retrieving subsequent pages.
