Can HTTP GET requests be considered safe for repeated execution without changing the result?

An HTTP GET request is considered idempotent and safe in the sense that it is intended to retrieve data without changing the server's state. Repeating a GET request should not alter the result or the resource's state.

However, in practice, this depends on the server implementation. If the server correctly follows standards, GET requests should have no side effects and can be safely repeated.

Example of a GET request in Node.js using fetch:

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data));

Repeating such a request will not change the server's state and will return the same data (unless it has changed on the server side).
