paper-lookup

To search academic papers across multiple databases simultaneously, use a keyword query to retrieve metadata and citations from up to 10 scholarly sources including PubMed, arXiv, and Semantic Scholar via their REST APIs.

Yes, you can find a specific scholarly article by its DOI. The lookup tool queries databases like Crossref and Unpaywall to retrieve exact paper metadata and full text links.

Yes, you need multiple API keys to retrieve scholarly literature metadata. The tool requires authentication with various academic databases via their REST APIs to facilitate successful literature review queries.

Supported academic databases for scholarly literature search include PubMed, PMC, bioRxiv, arXiv, OpenAlex, Crossref, Semantic Scholar, CORE, and Unpaywall, accessed via their REST APIs.

The best way to retrieve full text and citations from bioRxiv or arXiv is to use a multi-database search command with your target keywords, which queries these specific servers via REST API to return matching papers.

A key limitation when retrieving metadata from multiple academic databases is the strict requirement for valid API keys for each source, without which authentication fails and the scholarly literature query returns no results.
