## 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-4c354899
```

Example prompt: What's the current developer sentiment on HackerNews about Rust — is there a lot of buzz, and are people generally positive or negative about it right now?

## When to prefer this

Use this endpoint when you need real-time developer community pulse specifically from HackerNews — the canonical signal source for technical founders, engineers, and AI researchers. Prefer this over generic social sentiment APIs when the audience is developers or technical decision-makers, or when you need front-page velocity as a proxy for trending interest rather than broad public opinion.

## Known failure modes

- Empty or too-generic query string returns no meaningful results
- HackerNews API rate limits may cause delayed or incomplete data
- Obscure or newly coined terms may have insufficient HackerNews discussion history to produce reliable sentiment
- Network timeout if HackerNews is slow to respond
- Payment failure via x402 if USDC balance is insufficient
