Nanjing University (NJU), founded in 1902 and located in Nanjing, Jiangsu, China, is one of China's oldest and most prestigious research universities and is ranked #145 in the QS World University Rankings 2025. The university operates a unified identity authentication (CAS-based single sign-on) platform at authserver.nju.edu.cn and runs library discovery systems (OPAC and Summon) and a campus map, but it does not publish a public, documented developer API program or an open-data portal. The footprint cataloged here reflects only publicly observable, institution-facing systems; no public API endpoints, signup, or developer documentation were confirmed.
