What kind of service/API is it?

I am still for an answer from IT. But I went to their resource and did a lookup over browser for a cuid and it gave me back a table with a unique UID and GID 

If I can consume that through an API and query username and get UID/GID, is there a SSSD can make the same call to generate UID/GID for linux?
