CDISC Analysis Results Standard (ARS) API is one of 10 APIs that [Cdisc](https://apis.io/providers/cdisc/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Analysis Results, Clinical Trials, and Standards. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and a support channel.

The Analysis Results Standard surface of the CDISC Library API — 17 read operations that expose published ARS packages and their reporting events: planned analyses, analysis sets, data subsets, groupings, statistical methods and their operations, outputs, displays and categorizations. Served from the same production host and behind the same api-key as the rest of the CDISC Library.
