## 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-1f8e895a
```

Example prompt: What's the current developer sentiment on HackerNews about Svelte — is there a lot of buzz, and are people generally positive or critical about it?

## When to prefer this

Use this endpoint when you need real-time developer community sentiment specifically from HackerNews — the gold standard for technical and startup opinion. Prefer this over general social sentiment APIs when your audience is engineers, founders, or technical decision-makers. Ideal for competitor intelligence, library adoption decisions, AI model reception checks, and startup PR monitoring within the developer ecosystem.

## Known failure modes

- Very niche or obscure topics may return sparse or zero results
- HackerNews API rate limits could cause timeouts or degraded responses
- Sentiment may be skewed if topic is very new with few posts
