The /ISO3166Alpha3Country API provides a comprehensive list of all countries in the ISO 3166 Alpha-3 format. This API is essential for populating country selection fields in the frontend applications, ensuring consistency and compliance with international standards.

Functionality:

• Retrieve Country List: The API returns a list of countries using the three-letter ISO 3166-1 Alpha-3 code, which is the international standard for representing country names.
• Front-End Integration: The country list retrieved from this API can be directly used in drop-down menus, forms, and any other front-end elements where users need to select their country.
