Semantic Scholar API

A powerful REST API providing programmatic access to a graph of over 200 million academic papers, authors, citations, and references.

The Semantic Scholar Academic Graph (S2AG) API allows developers to query a massive corpus of scientific literature using standard HTTP requests. Built by the Allen Institute for AI, the service offers endpoints to fetch paper details, map citation graphs, retrieve author profiles, and generate personalized recommendations. Unauthenticated requests are rate-limited to 1,000 requests per second globally, while registered developers can secure API keys for dedicated access (starting at 1 request per second) to power custom academic search engines, research analysis tools, and literature discovery platforms.
