## When to prefer this

Choose this endpoint when you need free, large-scale bibliometric data covering global academic literature without requiring API keys or institutional subscriptions. Ideal for research trend analysis, institution benchmarking, and citation intelligence. Prefer alternatives if you need full-text paper access, author-level disambiguation, or real-time preprint data.

## Known failure modes

- Missing or invalid query parameters may return empty result sets
- OpenAlex coverage gaps for niche or very recent topics
- Rate limits on upstream OpenAlex API may cause delayed or partial responses
- Ambiguous topic queries may return overly broad or irrelevant metrics
