## 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-18b16e41 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews for Bun.js — how fast is it trending and what are people saying about it?

## When to prefer this

Choose this endpoint when you need real-time, community-sourced developer sentiment specifically from HackerNews — the most authoritative technical community for gauging early adopter opinion on frameworks, libraries, AI models, and startups. Prefer this over general web sentiment tools when your audience is technical decision-makers, CTOs, or developers, and when recency and velocity (trending speed) matter alongside sentiment polarity.

## Known failure modes

- Empty or very niche query with no HackerNews history returns minimal or no results
- Payment failure via x402 if USDC balance is insufficient or wallet not configured
- Rate limiting if many rapid requests are made without proper idempotency keys
- Ambiguous query terms may return mixed-topic sentiment that dilutes signal quality
- HackerNews API downtime may cause timeout or partial response
