## 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-9c0379ab
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for 'Deno' — are developers excited, skeptical, or indifferent right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical source for technical founder and engineer opinion. Prefer this over general social media sentiment tools when your audience is developers, CTOs, or technical investors who weight HackerNews consensus heavily. Ideal for pre-investment due diligence on startups, framework/library adoption research, or monitoring how a new AI model or product launch is being received by the developer ecosystem.

## Known failure modes

- Empty or overly generic query returns low-signal or no results
- Obscure or niche topics may have insufficient HackerNews coverage for meaningful sentiment
- Payment failure (HTTP 402) if x402 USDC payment is not properly handled
- Rate limiting or timeout if HackerNews API is slow or unavailable
- Query keyword too broad (e.g. 'AI') returns overwhelming noise without actionable signal
