specific access rights for various resources.
- This ensures fine-grained control over who can view, modify, or manage APIs
and related resources.
### 🪪 **Detailed Access Control**
- Downstream APIs can receive user profile information from Mycelium, allowing
them to customize responses based on the user's role and permissions.
### **Endpoints protection by role**
- Downstream APIs can be protected by role and specific permissions, ensuring
that only users with the appropriate access level can interact with them.

unauthorized access to downstream services.
