[Cloud]Basic question about what I can do with EquinixFabric API.

For example, if I want to use Equinix Fabric to set up and operate AWS, is it possible to use the EquinixFabric API for management within AWS (EC2 startup, life-and-death monitoring, etc.)?
Or is it necessary to use APIs provided by AWS?
When using multiple Azure and GCP, it is a concern to use the API provided by each.
Thank you.
