## When to prefer this

Choose this endpoint when you need structured bibliographic metadata (authors, DOI, citation counts, abstracts) for academic papers across any discipline, especially when you want open-access PDF links or need to sort results by citation impact or recency. It covers 250M+ works via OpenAlex, making it broader than discipline-specific databases. Prefer it over general web search when you need structured scholarly metadata rather than free-form text results.

## Known failure modes

- Empty results if query is too narrow or uses jargon not indexed by OpenAlex
- No open-access PDF link if paper is paywalled and no OA version exists
- Abstract may be missing for older or less-indexed papers
- sort parameter ignored if invalid value provided (defaults to relevance)
- limit must be 1-25; values outside range may return errors or be clamped
- from_year filter may exclude relevant cross-disciplinary works if year is set too restrictively

## How this service works

Academic paper search across 250M+ works (OpenAlex): title, authors, year, venue, DOI, open-access PDF link, citation count and abstract. Sort by relevance, most recent or most cited.

## Output

Returns a list of academic paper records, each containing title, author list, publication year, venue/journal name, DOI, open-access PDF URL (if available), citation count, and abstract — drawn from the OpenAlex database of 250M+ scholarly works, ranked by relevance, recency, or citation count.
