## 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-fa5c32c6
```

Example prompt: What's the current HackerNews developer sentiment and front-page velocity for the Rust programming language — are developers hyped, skeptical, or neutral about it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — particularly for technology evaluation, startup buzz monitoring, framework adoption signals, or AI model reception. Prefer this over generic social sentiment APIs when the target audience is developers and engineers, as HackerNews is uniquely concentrated with that demographic. Best used for quick pulse checks before product launches, competitive analyses, or investment research into tech-adjacent topics.

## Known failure modes

- Empty or overly generic query returns low-signal or no matching discussions
- HackerNews API rate limits or downtime may cause stale or missing results
- Rare or very niche topics may yield insufficient data for meaningful sentiment
- Ambiguous query terms (e.g. 'Apple') may conflate unrelated discussions
- Payment failure (HTTP 402) if USDC balance is insufficient for the $0.01 per-call fee
