## 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-33b031ac
```

Example prompt: What's the current developer sentiment on HackerNews for 'Deno' — is it getting positive buzz, negative pushback, or mostly ignored right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-centric sentiment specifically from the HackerNews community — ideal for gauging how technical audiences perceive a framework, startup, or AI model. Prefer this over general social media sentiment tools when the target audience is software engineers and technical founders, or when HackerNews front-page velocity is a relevant signal for your use case.

## Known failure modes

- Empty or too-short query string returns validation error
- No HackerNews discussions found for obscure or misspelled keyword returns empty/low-confidence result
- Rate limiting or upstream HackerNews API unavailability may cause timeout or degraded response
- Payment failure via x402 protocol blocks the request before processing
- Very broad queries (e.g. 'AI') may return noisy or low-specificity sentiment
