NTHU Library Discovery (Primo VE tenant) is one of 4 APIs that [National Tsing Hua University](https://apis.io/providers/nthu/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Library, Discovery, and SAML. The published artifact set on APIs.io includes API documentation.

NTHU Library's discovery service on Ex Libris Primo VE. Notable for what it reveals rather than what it offers: its sign-in link declares authenticationProfile=NTHU_SAML and auth=SAML, which is the only public evidence that NTHU operates its own SAML identity provider. The Primo public PNX search API was probed and returned HTTP 400 for an unauthenticated caller, and the corresponding OAI endpoint returns the same 403 as the research portal.
