Hello!

There is a small service that has a calculator.

You need to somehow allow users to install this calculator on the site.
But that they could do this only after registering, and having received a certain code for a certain site.

Tell me, maybe there are ready-made solutions, or in which direction to dig? I haven’t come across this at all before, I don’t even know where to start ;(

Thank you in advance!

You can make a calculator in JS so that it sends requests to your server and receives the result of the calculation in response. In this case, to fulfill a cross-domain request from your server, you will need to send the "Access-Control-Allow-Origin" header indicating the domain from which the request came, otherwise the client browser will not show it - cross-domain request security policy. And you benefit - you can collect query statistics.
That. when registering, you will give the client a code with some kind of key, which on your server can be unambiguously converted into one of the registered domains. And if there is one, you will return "Access-Control-Allow-Origin: tot_domen.tld" in the response headers

Well, here is the solution, as already mentioned above. When registering a user, ask for his website, solve it in the system, write a js script and send requests from it to your server, granting permission to the specific domain from which the request is coming. In short: js calculator script and php api.
You can try just an iframe, but this will probably be some kind of mockery
