## 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 x402-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-67e971e4
```

Example prompt: Can you check what HackerNews developers are currently saying about LangChain — I want to know the sentiment, how fast it's trending on the front page, and any notable discussion threads?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment and discussion velocity from HackerNews — particularly for evaluating technology adoption, startup reception, or AI model perception among technical audiences. Prefer it over general social media sentiment tools when the target audience is specifically software developers and the HackerNews community.

## Known failure modes

- Empty or whitespace query string returns a validation error
- Very niche or obscure keyword may return no results or low-confidence sentiment
- HackerNews rate limits or API downtime may cause upstream fetch failures
- Highly ambiguous single-letter or stop-word queries may produce irrelevant results
- Payment failure (HTTP 402) if x402 USDC micropayment is not processed correctly
