## 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 token-intel-agentdiet-dev-hackernews-developer-ecosystem-real-time-90c507c7
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around Next.js — are developers excited or critical about it right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-centric sentiment specifically from the HackerNews community — ideal for tracking startup launches, framework adoption, AI model reception, or YC-adjacent tech buzz. Prefer this over generic social sentiment APIs when the target audience is technical developers and founders rather than mainstream consumers.

## Known failure modes

- Empty or too-generic query returns low-signal or empty results
- Topic with no recent HackerNews activity returns minimal data
- Rate limiting or payment failure (HTTP 402) if USDC payment not attached
- Ambiguous keyword (e.g. 'apple') may conflate unrelated topics
- Service downtime or upstream HackerNews API unavailability
