Question

PHP

Hello everyone!) Can a site developer find out on which site his api is used?

Answer 1

If the JS in the tags is not an error, but something like JSONP is used, then it's easy. For users, referrer transmission is almost always enabled - everything will settle in the logs.
If the server apishka - then only the ip of the host in the logs. This is not enough to find out the domain name, but if you really want to, you can try to find out something - write to the hoster, for example.

Answer 2

Naturally, api requests are processed on its own server
