There is no such file. Which wordpress plugin are you using?
It isn’t a file but interface to get structured information from a site in a text form. It’s called REST API.
It can be disabled by some of your plugins.
You can take a look at Tools > Site Health to see if it’s working correctly.

“?rest_route=/” is the alternative url for “wp-json/”
And by the look at screenshot it’s working. Possibly you need to fix something else for this plugin to work.
