Example prompt: Search Crossref for reported research funders on public health surveillance and give me up to 15 results with their DOI references and funder attribution.

## When to prefer this

Choose this endpoint when you need structured, citable funder attribution data for public health surveillance literature sourced from Crossref, especially when DOI references and publisher-level metadata are required. Prefer this over general web searches when you need machine-readable bibliometric funder data rather than narrative funding summaries.

## Known failure modes

- Query returns no results if search terms are too narrow or obscure
- Crossref metadata may be incomplete for some publications, resulting in missing funder fields
- max_results parameter out of range (must be 1–30) returns a validation error
- Malformed or overly long query string (>200 characters) may be rejected
- Upstream Crossref API unavailability causes service failure
