The University of Indonesia Library online public access catalogue, served at lib.ui.ac.id (lontar.ui.ac.id redirects to it), title "OPAC - Universitas Indonesia Library". LONTAR is library software developed at UI and run on UI infrastructure. The catalogue is a human-facing web application: no OAI-PMH provider, SRU/Z39.50 endpoint, JSON export or machine-readable contract was found on the host, so it is recorded as an institution-operated surface with no API, not as an API.
