## When to prefer this

Use this endpoint when you need structured, ranked Stack Overflow Q&A data for a specific programming or technical topic, especially when you want metadata like scores, view counts, answer counts, and author reputation to judge answer quality. Prefer this over general web search when the goal is specifically developer community knowledge rather than documentation or blog posts.

## Known failure modes

- Invalid or missing query parameter returns an error
- Rate limiting or quota exhaustion if payment fails
- Upstream Stack Overflow API unavailability causes empty or error response
- Very niche queries may return zero results
- Malformed sort or per_page parameters may return defaults or errors
