NTNU API Gateway (api.ntnu.no) is one of 7 APIs that [Norwegian University of Science and Technology](https://apis.io/providers/ntnu/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Gated, Identity, and Integration. The published artifact set on APIs.io includes authentication docs.

api.ntnu.no is an NTNU-operated API gateway serving internal and partner integrations. It is live and institution-run — responses carry NTNU's own X-TIA-Processed-by frontend-auth header — but every request is redirected to Feide (auth.dataporten.no) for OAuth2 authorization with scope "openid userid-feide profile" before any resource is reachable. No public API reference, OpenAPI description, scope catalog or self-service registration was found on any NTNU host; /docs, /openapi.json and /status all return the same Feide account-chooser page. Recorded as a real institution-operated surface whose contract is not published.
