## 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-podcast-advertising-leaderboard-preview-80bcf2fb
```

Example prompt: Show me the top 10 podcast advertising sponsors from the past 7 days ranked by podcast reach, and tell me how each one's rank has shifted compared to 30 days ago.

## When to prefer this

Use this endpoint when you need a quick, pre-computed snapshot of the top 10 podcast advertisers without pagination or filtering — ideal for dashboards, briefings, or trend monitoring. Prefer it over full list endpoints when you only need the leaderboard preview with rank movement context.

- Invalid metric enum value returns a 400 error
- No data available for the trailing window returns an empty or partial list
- Rate limiting or payment failure returns a 402 or 429 error
