## 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-4d54e923
```

Example prompt: What's the current HackerNews sentiment and discussion velocity around Next.js — are developers excited, critical, or indifferent right now?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment rather than general social media sentiment — particularly for technical topics like programming languages, frameworks, developer tools, AI models, and startups where HackerNews is a leading indicator of technical adoption and reputation.

## Known failure modes

- Empty or too-generic query returns low-confidence or empty results
- HackerNews API downstream outage causes no data returned
- Very niche or misspelled topic returns no matching discussions
- Payment failure via x402 results in 402 response before data is served
- Rate limiting if the endpoint is called too frequently
