## 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 json-repair-agentdiet-dev-hackernews-developer-ecosystem-real-time-7b0733a7
```

Example prompt: What's the current developer sentiment and HackerNews buzz around Bun.js — is it trending, and are developers mostly positive or skeptical about it?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — ideal for tracking how engineers and technical founders perceive a technology, startup, or AI model. Prefer this over general web sentiment APIs when the HackerNews developer demographic is your target signal, or when front-page velocity and discussion momentum are relevant metrics.

## Known failure modes

- Empty or too-short query string returns a validation error
- Obscure or very niche topics may return sparse or no HackerNews data
- HackerNews API rate limits or downtime may cause fetch failures or stale results
- Ambiguous keywords (e.g. 'apple') may return mixed or irrelevant sentiment data
- Payment failure via x402 returns HTTP 402 before any data is served
