CNDA — Central Neuroimaging Data Archive (XNAT) is one of 10 APIs that [Washington University in St. Louis](https://apis.io/providers/washington-university-in-st-louis/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Neuroimaging, Research Computing, XNAT, Research Data, and Gated. The published artifact set on APIs.io includes authentication docs.

WashU's neuroimaging data archive, running XNAT — imaging informatics software that originated at the university's own Neuroinformatics Research Group. cnda.wustl.edu resolves inside WashU's network and the platform genuinely is the institution's. It is recorded without a contract because none is publicly readable: every path probed, including the XNAT REST root /data/version and the OpenAPI document at /xapi/swagger.json, returns the same 23,725-byte login page at /app/template/Login.vm with HTTP 200. That is a soft-200 gate — a success code wrapping a sign-in form — and it is recorded as such rather than counted as an available API.
