What Semantic Scholar API does
The Semantic Scholar API, also called the Academic Graph API, is a REST API for finding and exploring scientific publication data. It is built for developers who create research tools and applications. The Academic Graph service returns on authors, papers, citations, venues and SPECTER2 embeddings, linked to Semantic Scholar pages. A Recommendations service suggests papers similar to a given paper, and a Datasets service provides download links for datasets built from the graph, including S2AG and the S2ORC corpus for NLP and text mining. Most endpoints work without a key under a shared rate limit, a requested API key gives higher limits, and the datasets are described as free and open.
