zero fetch --capability whale-momentum-agentdiet-dev-hackernews-developer-ecosystem-real-time-16807087
```

Example prompt: What's the current developer sentiment and front-page velocity on HackerNews for 'Bun' — is it gaining traction or losing steam among developers right now?

## When to prefer this

Choose this endpoint when you need real-time developer community reaction — not lagging social media or blog roundups — specifically from the HackerNews audience (engineers, founders, early adopters). It is best suited for gauging technical consensus, controversy, or momentum around frameworks, libraries, AI models, and developer-facing startups. Prefer it over general web sentiment tools when the target audience is specifically the technical/developer demographic that congregates on HackerNews.

## Known failure modes

- Empty or ambiguous query string returns no meaningful sentiment data
- HackerNews API rate limits or downtime cause stale or missing results
- Niche or very new topics may have insufficient discussion volume for reliable sentiment
- Misspelled or overly broad keywords may return unrelated discussions
- Payment failure via x402 returns HTTP 402 before any data is returned
