CodeSystem Concept Lookup

Given a code/system, or a Coding, get additional details about the concept, including definition, status, designations, and properties. One of the products of this operation is a full decomposition of a code from a structure terminology
In Aidbox, this is essentially the same as search Concept by system and code
GET [base]/fhir/CodeSystem/$lookup?system=http://loinc.org&code=1963-8
equals to
GET [base]/Concept?system=http://loinc.org&code=1963-8
The only difference is the response format.
With Concept Search you can do even more than just getting one concept. For example, you can search and filter by any concept elements.
POST [base]/CodeSystem/$lookup
More info can be found in the official doc.
