## 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 workflows-agentdiet-dev-hackernews-developer-ecosystem-real-time-b4f501ca
```

Example prompt: Can you check what developers on HackerNews are saying about LangChain right now — I want to know the sentiment and how fast it's trending?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment from HackerNews specifically, including front-page velocity and discussion momentum — rather than general web sentiment or social media analysis. Ideal for evaluating new frameworks, tracking startup buzz, or assessing AI model reception within the technical developer ecosystem.

## Known failure modes

- Empty or ambiguous query keyword returns no meaningful sentiment data
- HackerNews API downtime causes fetch failure or stale data
- Niche or very new topics may yield insufficient discussion volume for reliable sentiment
- Payment failure (402) if x402 micropayment is not properly handled
- Query too broad (e.g. 'software') returns noisy, low-signal results
