JSON, key with slash, how to get value?

Question

API

Hello
-
My background:
I have been working with requests and APIs for a long time, and I know very well how to get a key, or a value, or how to get a value by a key, but I first encountered slashes in the key when I started working with the WordPress API .

As you can see from the screenshot, I received a json with a key /oembed/1.0


If you think this is a joke, make a request:
https://yoursite.zona/wp-json/oembed/1.0

Question:

Where else in WordPress is there information about the list of languages ​​(multi-language) in WordPress API
Is it possible to process such key somehow to get {wpml_language.enum}

PSIf someone doesn't understand what I'm doing, I explain, I get WordPress data through the API to display this data using a JavaScript framework. I'm making a dynamic site without reloading pages.
