Columbia Academic Commons is one of 10 APIs that [Columbia University](https://apis.io/providers/columbia/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Research Repository, Institutional Repository, Open Access, Hyrax, and Blacklight.

Columbia University's institutional research repository, holding the scholarly output, theses and research data of the university. Unusually for this cohort it is NOT a vendor tenancy: it runs on Hyrax/Blacklight — open-source repository software the Libraries help maintain — on Columbia's own host and hardware, with Columbia's own DOIs. The repository is therefore institution-operated in full. It could not be verified on this run: every request, including the OAI-PMH path and including requests presenting full browser headers, returns an Anubis proof-of-work interstitial with HTTP 200 and a bot-check body. No contract, schema or OAI Identify response is claimed for it, and no scored pointer is emitted to the host, because an Anubis-challenged host is indistinguishable from a soft-404 to an automated prober.
