## 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 domain-osint-agentdiet-dev-hackernews-developer-ecosystem-real-time-b4de2f88
```

Example prompt: What's the current developer sentiment and HackerNews discussion velocity around 'Deno' — are developers excited, critical, or indifferent about it right now?

## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical signal for technical and startup ecosystem opinion. Prefer this over Twitter/Reddit sentiment APIs when your target audience is developers, engineers, or technical founders, and over static trend databases when recency and velocity matter. Especially useful for pre-launch research, competitive intelligence on technical tools, or monitoring community reaction to a release.

## Known failure modes

- Empty or very niche query returns no matching HackerNews discussions
- HackerNews API rate limiting may delay or block data retrieval
- Highly generic queries (e.g. 'software') may return low-signal broad results
- Payment failure via x402 returns 402 status without executing the query
- Misspelled or poorly formed query keyword yields no useful sentiment data
