The FHIR specification defines the $lookup and $expand operations supported by FHIR terminology services for looking up codes and expanding value sets, respectively.
To make it easier to work with the FHIR terminology operations, I've created this FHIR Terminology Service Client. It allows you to execute the terminology operations against FHIR servers without having to manually construct the requests. It therefore simplifies the interaction with the terminology services and lets you more easily navigate and explore the terminologies.
