# National University of Singapore

**APIs profiled:** 8

The National University of Singapore is Singapore's flagship public research university, ranked eighth in the QS World University Rankings 2025, and it is a near-perfect illustration of why a university is a federation of buyers rather than a producer. NUS operates exactly one substantial machine-readable API surface of its own: the federated identity service at vafs.nus.edu.sg, which publishes a live OpenID Connect discovery document, a JWKS, and signed SAML 2.0 metadata for entityID https://vafs.nus.edu.sg/adfs/services/trust, and which registers NUS as an identity provider in the Singapore Access Federation. Everything else that looks like an NUS API belongs to a platform NUS rents — ScholarBank@NUS is Atmire's DSpace, the learning management system is Instructure's Canvas, the blogs are CampusPress, the library guides are Springshare. NUS has an API gateway hostname at api.nus.edu.sg on a certificate issued to the university, and it returns HTTP 500 on every path. The campus shuttle bus API at nnextbus.nus.edu.sg is genuinely NUS's and genuinely live, but sits behind HTTP Basic credentials the university does not issue publicly. Most strikingly, NUS's own course vocabulary — modules, modular credits, prerequisite trees — has no public machine-readable expression from the university at all; the only OpenAPI describing NUS course data is published by NUSMods, a student organisation, from a non-NUS domain. There is no NUS developer portal, no institution-wide GitHub organisation, no public open-data portal, no llms.txt, and no self-service registration path to any NUS API.
