When utilizing a library that offers a LINQ-compatible API for querying the service, it is possible to use LINQ to get data from a Web API or other RESTful service. A few libraries, such LINQ to Twitter and LINQ to REST, are available that offer this feature.   Here's an illustration of how to use the LINQ and LINQ to REST libraries to obtain data from a Web API:  var client = new RestClient("https://api.example.com");
var request = new RestRequest("users", Method.GET);
var query = from user in client.Execute>(request).Data.AsQueryable()
where user.Age > 30
select user;
var users = query.ToList();  The request to the RESTful service in this example is sent using the RestClient class. The endpoint and the request method are specified using the RestRequest class (in this case, the "users" endpoint and the GET method). When the client has finished processing the request, it provides an object that may be further queried by converting it to an IQueryableT> object using the AsQueryable() method.   You can filter the returned data and receive a list of people who are older than 30 by using a LINQ query operator, in this case a Where operator. In a similar vein, libraries like Flurl and Refit offer capabilities for LINQ access to the RESTful service.   It's important to note that the intricacy of the RESTful service and the results it delivers may make the querying challenging and necessitate the use of additional custom code and handling.
