How do I use OKX API?

You can start using OKX APIs once created them!
For public REST APIs, you can just test them out in your browser, e.g. https://www.okx.com/api/v5/public/instruments?instType=SPOT.
For private REST APIs or WebSocket APIs, we recommend using tools like Jupyter Notebook, Postman, etc.

What's the difference between REST API and WebSocket API?

REST APIs require an HTTP request to be sent for every response you get. It's the best when you just want the current state of a resource and do not want or require ongoing updates, e.g. symbol data.
WebSocket APIs do not follow a request-response message pattern.
Once a TCP connection has been established, the WebSocket channel can send updates continuously without receiving another request. WebSocket APIs are the best when you want ongoing updates whenever they are available, e.g. market data.
