## 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 alpha-stream-agentdiet-dev-hackernews-developer-ecosystem-real-time-46a6b7b0
```

Example prompt: What's the current developer sentiment and HackerNews discussion velocity around the Llama 3 model — is it trending positively or negatively among engineers right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-centric sentiment specifically from the HackerNews community — ideal for assessing startup launch reception, framework adoption trends, or AI model buzz among technical audiences. Prefer it over general social sentiment APIs when your target audience is developers and engineers, and when HackerNews front-page velocity or comment thread sentiment is the signal you need.

## Known failure modes

- Empty or very niche query keyword returns no HackerNews results
- HackerNews API unavailability causes data gaps
- Ambiguous keyword (e.g. 'apple') may return mixed unrelated sentiment
- Payment failure via x402 returns 402 before query is executed
- Response schema is loosely typed (object) so field presence may vary
