## 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 cve-intel-agentdiet-dev-hackernews-developer-ecosystem-real-time-106784f1 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Bun' — are developers excited, skeptical, or just ignoring it?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — the authoritative signal for engineering and technical founder audiences. Prefer this over general social sentiment APIs when your topic is a framework, open-source library, AI model, or dev-focused startup, and you need front-page velocity (trending speed) in addition to opinion tone. Not suitable for Twitter/Reddit sentiment or non-technical audience signals.

## Known failure modes

- Empty or ambiguous query string returns no meaningful results
- Very niche or misspelled topic keyword yields sparse data
- HackerNews API or scraping layer is temporarily unavailable, causing a timeout or 5xx error
- Payment failure (402) if x402 USDC balance is insufficient
- Topic has no recent HackerNews activity, resulting in low-confidence sentiment output
