## 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 mcp-compiler-agentdiet-dev-hackernews-developer-ecosystem-real-time-c96de03c
```

Example prompt: What's the current developer sentiment on HackerNews for Next.js — are engineers excited about it, frustrated, or indifferent?

## When to prefer this

Choose this endpoint when you need real-time, developer-centric sentiment specifically from HackerNews — the primary community for technical founders, engineers, and early adopters. Prefer it over general social sentiment APIs when the target audience is developers and the goal is understanding grassroots technical reception rather than mainstream consumer opinion.

## Known failure modes

- Empty or too-short query string returns validation error
- Topic with no HackerNews presence returns sparse or empty results
- Rate limiting or payment failure (HTTP 402) if x402 payment not processed
- Ambiguous keyword may surface unrelated discussions
- Transient HackerNews API unavailability causes upstream timeout
