Yes, you can look up research papers using a DOI, arXiv ID, PMID, OpenAlex ID, Semantic Scholar ID, ORCID, or ISSN. The system accepts these various identifier formats to retrieve structured results and raw API responses from the queried databases.

Yes, you need API keys to access some academic databases like Semantic Scholar, CORE, NCBI, and OpenAlex. These keys are required dependencies for retrieving metadata, checking open access status, and generating citation graphs from the queried sources.

The best way to find open access copies is to search databases like Unpaywall and OpenAlex. The system checks the availability of open access copies and retrieves the full text when available, returning the open access status alongside the structured metadata.

Academic citation graph searches work by querying databases like Semantic Scholar and OpenAlex to map citation networks. This allows you to explore related studies and find papers by specific authors, returning structured citation data and raw API responses.

Your paper lookup returns both structured results and raw API responses to provide complete transparency. The structured metadata includes citation graphs and open access status, while the raw responses offer the direct database output for advanced analysis.
