## When to prefer this

Choose this endpoint when you specifically need community-sourced discussions and opinions from Hacker News about database selection and migration topics. It is ideal for developer research workflows where practitioner sentiment, real-world migration stories, and peer recommendations matter more than official documentation. Prefer this over generic web search when you want curated, scored, and attributed HN-specific results without scraping.

## Known failure modes

- No results found if HN has few matching stories for the query — returns empty list
- Query too broad or too narrow may return irrelevant or zero results
- max_results exceeds allowed maximum of 10 — API will reject or cap
- Network or upstream HN API unavailability causing timeout or error response
- Payment failure (x402) if USDC balance is insufficient
