## 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-4ab61e8d
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around LangChain — are developers excited about it or is there a backlash forming?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment from HackerNews specifically — particularly useful for gauging grassroots tech opinion on frameworks, AI models, startups, or libraries before adoption or investment decisions. Prefer this over generic social sentiment tools when the target audience is specifically developers and technical practitioners, and when HackerNews front-page velocity is a meaningful signal for your use case.

## Known failure modes

- Missing or empty 'query' parameter returns a 400 validation error
- HackerNews upstream API unavailability causes delayed or failed responses
- Very niche or obscure topics may return sparse or no discussion data
- Payment failure via x402 returns a 402 Payment Required response
- Ambiguous single-word queries may return mixed results across unrelated topics
