## 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-guest-brand-suitability-profile-94639946
```

Example prompt: Can you pull up the IAB brand-suitability profile for podcast guest 'joe-rogan' on Particle Pro — I want to see how his appearances break down across brand-safety tiers and which content categories keep getting flagged?

## When to prefer this

Use this endpoint when you need to evaluate a podcast guest's aggregate brand-suitability risk based on their full appearance history across shows, rather than assessing a single episode or show. It is ideal for pre-campaign due diligence, advertiser compliance checks, or influencer vetting workflows where IAB Tech Lab tier compliance is a requirement.

## Known failure modes

- Unknown guest ID or slug returns a 404 not found error
- Malformed or unencoded UUID in path returns a 400 bad request
- Guest has no analyzed podcast appearances, resulting in empty or null distribution
- Insufficient credits or failed x402 payment returns a 402 payment required error
- Rate limiting or quota exceeded returns a 429 too many requests error

## Output
