Example prompt: Can you pull up structured citation records on public health surveillance — give me the top 10 results with DOIs and source attribution from Crossref publisher metadata?

## When to prefer this

Choose this endpoint when you need structured, DOI-linked academic citation records specifically for public health surveillance literature, sourced from Crossref publisher metadata. It is best suited for bibliography generation, research literature review, and source verification tasks where structured citation data (not full-text content) is the goal. Prefer this over general web search endpoints when you need citable, publisher-attributed academic references rather than live web page results.

## Known failure modes

- max_results outside range 1–30 — validation error
- No matching citations found for niche query — empty result set
