# Using Tools to Call the API Server

After the program starts, we can use tools such as Postman to debug CLTPlatform. Below is a simple example of calling an interface.

After opening Postman, fill in the request information for the test interface as shown below. Click Send, and if you see information returned, it indicates that the server has started successfully.

# Calling the Server via Command Line

Alternatively, you can simply use the command line to make a network request to check if the server has started.
