## 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 x402-audit-agentdiet-dev-hackernews-developer-ecosystem-real-time-d548b2c9 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews about Deno — are there active front-page discussions, and is the community buzz positive or negative?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — the canonical source for technical founder and engineer opinion. Prefer it over general web sentiment tools when the target audience is developers, when you care about front-page velocity as a proxy for trending topics, or when evaluating a framework, AI model, or startup's reception in the technical community. It is particularly well-suited for investment research, developer relations monitoring, and competitive intelligence in the tech ecosystem.

## Known failure modes

- Empty or too-broad query returns low-signal or no matching discussions
- Very niche or obscure topic may return sparse results if HackerNews has little coverage
- Network or upstream HackerNews Algolia API outage causes service unavailability
- Malformed or missing 'query' field returns a 400-level validation error
- Payment failure via x402 protocol results in 402 response and no data returned
