## When to prefer this

Prefer this over generic search APIs when you specifically want Crossref-sourced bibliographic records with DOI links.

## Known failure modes

- Query returns zero results if the topic is too niche or misspelled
- max_results exceeding 30 returns a validation error
- Crossref metadata may be incomplete or missing for some DOIs
- Slow or unavailable upstream Crossref data may cause timeouts or empty responses
