## 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 hn-pulse-agentdiet-dev-hackernews-developer-sentiment-pulse-802d9946
```

Example prompt: What's the current developer sentiment on HackerNews about LangChain — are people excited or critical, and how fast is it trending on the front page?

## When to prefer this

Choose this endpoint when you specifically need real-time developer community sentiment from HackerNews — the primary signal source for technical audience opinion — rather than broad social media sentiment. Best for evaluating tech stacks, monitoring startup reception, tracking AI model launches, or competitive developer ecosystem analysis where HN is the authoritative community.

## Known failure modes

- HackerNews topic too niche to surface meaningful sentiment
- Rate limiting or payment failure returns HTTP 402
- Newly coined terms not yet discussed on HackerNews yield sparse data
- Query keyword ambiguous across multiple products returns mixed signal
