How to parse text on a page generated by js using JS or PHP?

Question

PHP

There is an online translator deepl.com. You need to send a request for translation using PHP or JavaScript and somehow pick up the translation. The request itself can be sent by referring to the link:

https://www.deepl.com/translator#en/es/Hello world



where
- "#en/es" - indicates the direction of translation
- "/Hello world" - the text to be translated

As a result, when we access this link through the browser, we get an HTML page that does not contain a translation in its body (in the HTML code of the page itself) (the text itself that we can see in the browser). It is loaded with JS scripts. If I track requests in the "Network" tab in the developer console, then I find the last request (XHR type) that makes some kind of js script (utils.chunk.$f32843.js initiator:https://www2.deepl.com/jsonrpc and in the response JSON arrives in which there is a translation.



Now the main question: Is it possible (and if so, how) to get this translation text (for example, get this JSON response) using a PHP or JS script. If it's not difficult, I'll be grateful if you give an example code in PHP or JS.
