## 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 defi-yield-agentdiet-dev-hackernews-developer-ecosystem-real-time-04a4df2d
```

Example prompt: Can you pull the live HackerNews sentiment and front-page discussion velocity for 'Bun' — I want to know how the developer community is currently feeling about it?

## When to prefer this

Use this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — particularly for evaluating startup launches, framework adoption trends, AI model reception, or open-source library momentum. Prefer this over general web sentiment tools when the target audience is specifically the technical/developer community and HN front-page velocity is a meaningful signal.

## Known failure modes

- Empty or no results if the query keyword has no recent HackerNews coverage
- Ambiguous keywords may match unintended discussions (e.g. 'Apple' matching fruit vs tech company)
- Rate limiting or payment failure on the x402 micropayment layer
- Stale or low-signal results if the topic is niche and infrequently discussed
- Generic response schema with no guaranteed field structure returned
