## When to prefer this

Choose this endpoint when you need real-time developer community sentiment specifically from HackerNews — the canonical source for startup, framework, and AI model reception among technical audiences. Prefer this over generic social sentiment APIs when the target audience is developers, founders, or early adopters rather than mainstream consumers.

## Known failure modes

- Empty or very niche query terms may return no HackerNews results
- HackerNews API rate limits or downtime may cause fetch failures
- Ambiguous keywords (e.g. common words) may return irrelevant discussions
- Payment failure via x402 protocol may block the request
- Very recent topics may have insufficient discussion volume for meaningful sentiment
