## 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 whale-momentum-agentdiet-dev-hackernews-developer-ecosystem-real-time-8e09a70a
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around 'Anthropic' right now — are developers excited or skeptical?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical source for technically sophisticated developer opinion. Prefer this over generic social media sentiment tools when the target audience is developers, engineers, or startup founders, and when HackerNews front-page velocity and discussion depth matter more than broad social reach.

## Known failure modes

- Empty or whitespace query string returns a validation error
- Very niche or obscure keyword may return sparse or no results
- Rate limits or upstream HackerNews API unavailability may cause timeouts
- Payment failure (HTTP 402) if x402 micropayment is not properly handled
- Ambiguous keywords may return mixed or irrelevant discussions
