What is query language? SQL is Structured Query Language and you use it to query your database for data you are interested in. It does not have to do anything with your API. If you ever were working with big XML files you probably used XQuery or XPath, query languages designed to XML for data. There are specialized languages that are designed to work with APIs to query them for data. For example, you probably heard about GraphQL or even used it when you were working with some API.
