## 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 scout-dx-hugen-tokyo-45897549
```

Example prompt: Can you scout Hacker News for recent discussions about LLM agent frameworks and surface the most relevant posts or signals?

## When to prefer this

Use this endpoint when you need programmatic access to Hacker News community discussions, signals, or posts for a given topic, and you are operating in an x402-compatible payment environment on Base or Solana. Prefer this over general web search when HN community sentiment or developer discourse is specifically desired.

## Known failure modes

- Payment not provided or invalid x402 header — 402 Payment Required
- No matching HN content found for query — empty or null results
- Query parameter missing — 400 Bad Request
- Network or upstream HN data unavailability — 503 or timeout

## How this service works

## Output
