## How to call it through Zero

```sh
zero fetch --capability particle-pro-stories-list-c0c0559c
```

Example prompt: Pull the first page of clustered news stories from Particle Pro so I can see what the top trending topics are right now.

## When to prefer this

Use this endpoint when you need a high-level feed of clustered, deduplicated news stories rather than raw individual articles. Prefer this over the articles endpoint when you want topic-level groupings rather than individual article-level detail. Ideal for news briefings, trend monitoring, and content curation workflows where topic clustering adds value.

## Known failure modes

- Invalid pagination parameters return a 400 error
- Exceeding rate limits or insufficient USDC balance returns a 402 payment required error
- Network or server errors return 500-level responses
- Empty result set if no stories are currently available
- Malformed cursor or page token leads to pagination errors
