What is an API?

Last updated on May 08, 2023

An API (Application Programming Interface) is a software architecture that allows computer systems to interact with each other. In every piece of software you use, there is some way of API integration. By using API's developers can save hundreds of hours because they 'plug in' to the work another developer previously did.


REST (Representational State Transfer) is a certain standardised API and a way to exchange data with other systems in a structured way. Typically, data is transferred via a REST API via JSON. Refer below for an example of our API.

### GET https://api.proxeuse.com/ping
  "status": "success",
  "code": 200,
  "message": "pong",
  "data": {
    "ip": "",
    "method": "GET",
    "input": [],
    "headers": []

The above result is a result of a simple HTTP GET request to the endpoint found at https://api.proxeuse.com/ping. Feel free to try it out yourself! We have many open APIs, which you can read more about here.
