The SAS REST API documentation is readily available at the following url: https://developer.sas.com/apis/rest/
Due to the sheer amount of documentation available, this site can take a while to load, and it is not possible to search everything in one go.
A useful workaround then is to simply scrape the site and load it locally. The following command (Linux systems) will serve:
wget \ --recursive \ --no-clobber \ --page-requisites \ --html-extension \ --convert-links \ --restrict-file-names=windows \ --domains developer.sas.com \ --no-parent \ https://developer.sas.com/apis/rest/
