## 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 mesh-agentdiet-dev-hackernews-developer-ecosystem-real-time-sentiment-64377025 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around Anthropic's Claude — are developers excited, skeptical, or mixed?

## When to prefer this

Choose this endpoint when you need real-time developer community pulse specifically from HackerNews — the canonical source for technical founders, engineers, and early adopters. It is ideal for tracking how a new framework, AI model, startup, or library is being received in the developer ecosystem, especially when you need velocity (trending speed) not just static search results. Prefer this over general web search when the target audience is developers and technical decision-makers.

## Known failure modes

- Empty or too-generic query string returns low-signal results
- Very niche or brand-new topics may return sparse HackerNews data
- Rate-limited or temporarily unavailable HackerNews upstream may return stale results
- Payment failure (x402) prevents execution if USDC balance is insufficient
- Ambiguous query keyword (e.g. 'go') may surface unrelated discussions
