## 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-107b90bd -d '<json body>'
```

Example prompt: What's the current developer sentiment and HackerNews discussion velocity for Remix.js — are people excited about it or is it losing steam?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — particularly useful for tracking how a framework, startup, library, or AI model is perceived by the technical community at this moment. Prefer it over general web search sentiment tools when the target audience is specifically developers and the HackerNews community, or when front-page velocity and discussion thread depth matter as signal quality indicators.

## Known failure modes

- Empty or overly generic query returns low-signal results with no actionable sentiment
- Very niche or obscure topics may return sparse HackerNews data
- Rate limiting or upstream HackerNews/Algolia API unavailability may cause timeouts
- Payment failure via x402 protocol results in 402 response before execution
- Idempotency-Key collision may return cached prior result unexpectedly
