I can't manage to use Firefly API

Hello everyone,

I am trying to figure out why I cannot an Adobe project using the Firefly API. Some context:

I only paid for Firefly when creating my account. I try to follow these steps https://developer.adobe.com/firefly-services/docs/guides/get-started/, creating a project and then adding the Firefly services API. However, when I try the API seems unavailable. Looking for the API on the catalog, it shows this message:

I can only see 1 API on the admin console:

How can I enable the Firefly API? Am I supposed to have access, and if not, how can I have it?
