## 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 x402broker-com-hackernews-developer-ecosystem-real-time-sentiment-pulse-f75d3ef4
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around 'Llama 3' — are developers excited, skeptical, or mixed?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal for technical founder and early-adopter opinion. Prefer this over generic social sentiment APIs when your audience is developers, engineers, or startup founders, and when HackerNews front-page velocity is a meaningful signal (e.g. evaluating a new open-source library, AI model, or startup's community traction).

## Known failure modes

- Empty or too-broad query returns noisy or irrelevant results
- Obscure or very new topics may return no HackerNews discussions
- HackerNews API downtime may cause fetch failures or stale data
- Rate limiting or payment failure (HTTP 402) if x402 payment is not properly handled
- Misspelled or abbreviated topic names may miss relevant threads
