Europe PMC as an API, powered by EMBL-EBI — an open repository of biomedical and life-sciences literature covering 45 million+ abstracts and 9 million+ full-text articles drawn from PubMed, PubMed Central, preprint servers (bioRxiv and medRxiv), patents and Agricola. Search the literature with rich field syntax (by author, title, journal, MeSH term, publication year or open-access status), ordering results by relevance, date or citation count, and optionally restricting to preprints only; read an article's full metadata and abstract — its authors, journal, volume and pages, DOI, PubMed and PMC identifiers, MeSH terms, keywords, funding grants and links to the free full text; and walk the citation network in both directions: the articles that cite a given paper, and the works that paper itself references. Together these let you measure scholarly impact, build citation graphs, track a research topic across preprints and peer-reviewed papers, and feed evidence into bibliometric, systematic-review and research-intelligence tools. Article identifiers are PubMed ids (numeric), PMC ids (PMC…) or preprint ids (PPR…); the source defaults to PubMed (MED). Data from EMBL-EBI Europe PMC.

Look up an InterPro entry — a family, domain, repeat, conserved/binding/active site or post-translational modification — with its description, Gene Ontology terms and the member-database signatures that define it; search entries by name and type; read a protein's metadata; and, most usefully, list the InterPro entries found on a protein together with their start–end positions, so you can see a protein's domain architecture. Ideal for protein annotation and function prediction, comparative genomics, structural-biology and bioinformatics pipelines, and research and teaching tools. Entry ids are IPR followed by six digits; protein ids are UniProt accessions. Data from EMBL-EBI.
