## 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 onchain-risk-agentdiet-dev-hackernews-developer-ecosystem-real-time-85f17570
```

Example prompt: What's the current HackerNews sentiment around Llama 3 — are developers excited or skeptical, and how fast is it moving on the front page?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the primary forum for startup founders, engineers, and YC-ecosystem participants. It is ideal for tracking how technical audiences react to new AI models, frameworks, libraries, or startup launches, especially when front-page velocity and live discussion depth matter more than broad social media coverage.

## Known failure modes

- Empty or too-generic query string returns low-signal results
- Topic with no recent HackerNews coverage may return sparse or null sentiment data
- Rate limiting or payment failure (HTTP 402) if x402 USDC payment is not properly configured
- HackerNews API downtime may cause delayed or stale results
- Ambiguous query keywords (e.g. 'apple') may return mixed or irrelevant results
