# USC Digital Library API (Orange Logic Cortex)

**Canonical:** https://apis.io/apis/usc/digital-library-cortex/

**Documentation:** https://digitallibrary.usc.edu/

USC Digital Library API (Orange Logic Cortex) is one of 8 APIs that [University of Southern California](https://apis.io/providers/usc/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Research Repository, Digital Collections, Orange Logic, Cortex, and Library. The published artifact set on APIs.io includes an API reference.

A live, token-gated REST API on USC's own host running Orange Logic's Cortex digital asset platform. GET https://digitallibrary.usc.edu/API/search/v3.0/search?query=test&format=json returns 401 application/json with a fully formed Cortex envelope — APIRequestInfo naming ProviderVersion PRINCETON.R6.2293U.273257, ProviderIdentity USC-AWS-ORG-209, Module search, APIVersion v3.0 — and the message "you must be signed in to access to this functionality. Please request a token through the Authentication." /API/Authentication/v1.0/Login answers 405 to GET, confirming the auth resource exists. The deployment, the host, the 1.5 million DOIs it mints as DataCite client usc.dl and the collections themselves are USC's; the contract is Orange Logic's product API, identical across every Cortex customer, so no spec is saved under USC. Tokens are not self-service and there is no public API documentation on any USC host, so this surface is recorded but not readable.
