## 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-f69e3307 -d '<json body>'
```

Example prompt: What's the current HackerNews sentiment and front-page velocity for Rust — are developers excited about it, and how actively is it being discussed right now?

## When to prefer this

Choose this endpoint when you need real-time, live developer community sentiment specifically from HackerNews — the canonical source for technical founders, engineers, and early adopters. Prefer this over generic social sentiment APIs when your audience is the developer/startup/hacker ecosystem, or when you need front-page velocity as a signal of trending traction among technical users.

## Known failure modes

- Empty or missing query string returns a validation error
- Very niche or obscure topic with no HackerNews coverage may return sparse or empty results
- Payment required (HTTP 402) if x402 micropayment header is not included or invalid
- Rate limiting or upstream HackerNews API outage may cause delayed or failed responses
- Non-English or highly abbreviated query terms may produce poor sentiment coverage
