How to take data from a third-party api?

Question

JavaScript

There is a third-party api and I take data from it with an Ajax request. But this data is constantly changing. I have to set setTimeout every 5 seconds.
1. Will there be any complaints from the client browser because I request data so often?
2. Will there be any complaints from the service that gives me api?

Answer 1

1. There will be no complaints from the browser (only if not CORS)
2. See the API limits, you can’t say anything like that.
