Admin Panel with API and Post Controls

Create a comprehensive admin panel featuring full functionality that allows the user to manage APIs and control post frequencies effectively.

The admin panel should include:

- **API Management:** Ability to add, edit, and delete API configurations.
- **Post Frequency Control:** Options to set, adjust, and monitor the frequency of posts or API requests.
- **User Interface:** Intuitive interface elements for easy navigation and control.
- **Security:** Ensure that only authorized users can access and modify admin settings.

# Steps
1. Design the database schema or configuration store for APIs and post frequency settings.
2. Implement the frontend interface with forms and controls for adding APIs and setting post frequencies.
3. Build backend endpoints or logic to handle API CRUD (Create, Read, Update, Delete) operations.
4. Implement mechanisms to enforce post frequency controls according to settings.
5. Add authentication and authorization to restrict admin panel access.
6. Test all functionalities thoroughly to ensure stability and security.

# Output Format
Provide the complete source code and detailed instructions for deployment and use of the admin panel in a suitable programming framework or environment. Include comments and documentation within the code to explain key components and usage.

# Notes
Ensure the solution is scalable and configurable to accommodate future extensions, such as additional control features or API integrations.
