## 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-4cd6d5fc

Example prompt: What's the live HackerNews sentiment and front-page velocity right now for 'Anthropic' — are developers bullish or critical?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — as opposed to general social media sentiment tools — for technical topics like frameworks, AI models, libraries, or developer-focused startups. It is ideal when the target audience is software engineers and the signal source (HackerNews front-page velocity and discussion threads) is specifically relevant to your use case.

## Known failure modes

- Empty or too-broad query returns low-signal or noisy results
- Keyword not found in recent HackerNews activity returns empty or minimal results
- Payment failure (HTTP 402) if x402 USDC payment is not provided or insufficient
- Rate limiting or upstream HackerNews API unavailability causes timeout or error
- Highly generic keywords (e.g. 'AI') may return overwhelming undifferentiated results
