## 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 onchain-risk-agentdiet-dev-hackernews-developer-ecosystem-real-time-9b143fb2 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and front-page velocity around Deno — are developers excited about it, skeptical, or mostly ignoring it?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment rather than general social media sentiment. It is ideal for gauging how technical audiences on HackerNews are reacting to a framework, startup, or AI model — especially when front-page velocity and discussion depth matter more than follower counts or likes. Prefer this over Twitter/X sentiment tools when the target audience is specifically software engineers and technical founders.

## Known failure modes

- Empty or ambiguous query returns no meaningful results
- Niche or newly coined technology names may yield sparse or no HackerNews data
- Payment failure via x402 protocol results in 402 response before processing
- HackerNews API downtime may cause delayed or incomplete results
- Very broad queries (e.g. 'AI') may return noisy, unfocused sentiment data
