## How to call it through Zero

```sh
zero fetch --capability hacker-news-top-stories-feed-e8a5b980
```

## When to prefer this

Use this endpoint when you need real-time top Hacker News stories without setting up API keys or signing up for a service. Ideal for AI agents that want pay-per-call access to HN trending content via USDC micropayments on Base. Prefer over direct HN API calls when working within an x402-enabled agent payment flow.

## Known failure modes

- Payment required (402) if x402 USDC payment header is missing or invalid
- top parameter out of range (must be 1-20) may return validation error
- Upstream HN API unavailability could cause timeout or empty results
- Requesting more than 20 stories returns an error or is clamped to max
