## 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 domain-osint-agentdiet-dev-hackernews-developer-ecosystem-real-time-95290122 -d '<json body>'
```

Example prompt: What's the current developer sentiment around Llama 3 on HackerNews — is the community excited, skeptical, or mostly quiet about it?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal for technical opinion leaders. Prefer this over generic social sentiment APIs when your audience is developers, engineers, or startup founders, or when evaluating the technical reception of a framework, AI model, or B2B SaaS product. Especially useful for live PR monitoring around launches, competitive intelligence on developer tooling, or tracking front-page velocity of emerging technologies.

## Known failure modes

- Empty or too-generic query keyword returning noisy or irrelevant results
- HackerNews Algolia API downtime causing stale or unavailable data
- Very niche or newly coined terms returning zero matching discussions
- Payment failure via x402 preventing request execution
- Rate limiting if the same idempotency key is reused incorrectly
