Is it possible to add a site with auth0 API?

OVERVIEW
Our company provides a service that allows the creation of service with no code. As one of its features, we would like to be able to set up social login for our community, and we are considering using your company as one of the means to do so.
So my question is, is it possible to add a site with auth0 API?

DETAILS
Our service provides multiple URLs for new user registration and user login screens.
As an example
https://aaa.xxxx.com/view/signin
https://bbb.xxxx.com/view/signin
https://aaa.bbb.co.jp/view/signin

In this case, is it possible to register or delete the domain to be used via API?
We would like to link our application with auth0 service at the timing when we set SNS authentication ON/OFF in our application.
If we try to achieve the same thing with another company’s service that implements social login, we need to add the URL from the admin screen of that service.
We would like to avoid having to make additional settings on the administration screen each time the number of clients increases.
If a client starts using our service and enables social login on our admin screen, we want to automatically enable social login on that domain as well.

SUMMARY
What we want to do
Start using our service → Enable social login on the client side admin screen of our service → Enable end users to use social login

What we do not want to do
Start using our service → Add URL to the social login service’s admin screen → Enable social login on the client-side admin screen → Enable end users to use social login
