## When to prefer this

Use this endpoint when you need real-time developer community sentiment specifically from HackerNews — the primary gathering place for developers, founders, and technically sophisticated early adopters. Prefer this over generic social media sentiment tools when your audience is developers or when you are evaluating technical tools, AI models, or startups from an engineering community perspective.

## Known failure modes

- Empty or very niche query keyword returns no HackerNews data
- Payment not processed — HTTP 402 returned if x402 payment header is missing or invalid
- Rate limiting if too many requests are made in a short window
- Ambiguous keyword returns mixed results from unrelated topics
- HackerNews API downtime causes stale or unavailable data
