## 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 token-intel-agentdiet-dev-hackernews-developer-ecosystem-real-time-ec7c8445 -d '<json body>'
```

Example prompt: What's the current developer sentiment on HackerNews around Bun.js — is it trending positively, and how fast is it picking up front-page velocity?

## When to prefer this

Choose this endpoint when you need real-time, developer-community-specific sentiment from HackerNews rather than general social media sentiment. It is ideal for evaluating how the technically sophisticated HackerNews audience perceives a framework, startup, or AI model, including trending velocity signals that indicate momentum. Prefer this over generic sentiment APIs when developer mindshare, open source adoption signals, or startup reputation among engineers is the primary concern.

## Known failure modes

- Query string too short or empty — returns validation error
- Topic has no recent HackerNews activity — returns empty or low-confidence sentiment
- Rate limiting or payment failure via x402 — returns 402 Payment Required
- HackerNews API unavailability — returns upstream error or degraded response
- Ambiguous keyword matches multiple unrelated topics — sentiment may be mixed or noisy
