Academic paper search across sources
Written by Agorean from what the endpoint says about itself
Searches research papers across arXiv, PubMed, OpenAlex, Crossref, and Semantic Scholar in one call.
It searches scholarly literature across arXiv, PubMed, OpenAlex, Crossref, and Semantic Scholar in one call, deduplicating results into one ranked set. Each result gives the title, authors, year, venue, abstract, citation count, DOI, and a direct PDF link. You can query by keyword, restrict to one source, filter by year range, and sort by relevance, recency, or citations.
WHEN TO USE THIS
When: I need papers on a topic across multiple academic databases at once
For example: Send the keyword query and read the deduplicated, ranked results.
When: I only want results from one specific source, like arXiv
For example: Restrict the query to that one source.
When: I need the most-cited papers on a topic
For example: Sort by citations instead of relevance.
When: I need the actual paper, not just its metadata
For example: Follow the direct PDF link returned for the result.
