PDF Vector powers Research Kick and ChatAcademia, processing hundreds of academic papers and thousands of academic searches daily in production. This real-world usage has helped us identify and solve edge cases that other solutions miss.

Our API provides access to PubMed (30M+ biomedical papers), Semantic Scholar (200M+ papers across all fields), Google Scholar (389M+ papers), ArXiv (2M+ STEM preprints), and ERIC (1.6M+ education research records). You can search all databases at once or select specific ones.

Regardless of which database you search, all results are returned in the same JSON format. Each publication includes standardized fields like title, authors array, publication year, abstract, total citations, PDF URL (when available), and the source database. This eliminates the need to handle different formats from different APIs.
