## 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 sec-intel-agentdiet-dev-hackernews-developer-ecosystem-real-time-55c9830a -d '<json body>'
```

Example prompt: What's the live HackerNews sentiment around Next.js right now — is the dev community excited, skeptical, or mixed?

## When to prefer this

Use this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — the canonical forum for developers, founders, and tech enthusiasts. Prefer this over generic social media sentiment tools when the audience is specifically developers or when evaluating technical frameworks, open-source libraries, AI models, or developer-focused startups. Ideal when you need front-page velocity and discussion momentum, not just keyword volume.

## Known failure modes

- Empty or too-short query string returns validation error (minLength:1 violated)
- Topic with very little HackerNews coverage may return sparse or no sentiment data
- HackerNews API downtime or rate limiting may cause upstream failures
- Ambiguous keywords (e.g. common English words) may return noisy or irrelevant results
- Payment failure via x402 results in 402 response before any data is returned
